Meng, Na, Nagy, Stefan, Yao, Danfeng, Zhuang, Wenjie, Arango-Argoty, Gustavo.  2018.  Secure Coding Practices in Java: Challenges and Vulnerabilities. 2018 IEEE/ACM 40th International Conference on Software Engineering (ICSE). :372-383.

The Java platform and its third-party libraries provide useful features to facilitate secure coding. However, misusing them can cost developers time and effort, as well as introduce security vulnerabilities in software. We conducted an empirical study on StackOverflow posts, aiming to understand developers' concerns on Java secure coding, their programming obstacles, and insecure coding practices. We observed a wide adoption of the authentication and authorization features provided by Spring Security - a third-party framework designed to secure enterprise applications. We found that programming challenges are usually related to APIs or libraries, including the complicated cross-language data handling of cryptography APIs, and the complex Java-based or XML-based approaches to configure Spring Security. In addition, we reported multiple security vulnerabilities in the suggested code of accepted answers on the StackOverflow forum. The vulnerabilities included disabling the default protection against Cross-Site Request Forgery (CSRF) attacks, breaking SSL/TLS security through bypassing certificate validation, and using insecure cryptographic hash functions. Our findings reveal the insufficiency of secure coding assistance and documentation, as well as the huge gap between security theory and coding practices.

Ghose, Nirnimesh, Lazos, Loukas, Li, Ming.  2018.  Secure Device Bootstrapping Without Secrets Resistant to Signal Manipulation Attacks. 2018 IEEE Symposium on Security and Privacy (SP). :819-835.
In this paper, we address the fundamental problem of securely bootstrapping a group of wireless devices to a hub, when none of the devices share prior associations (secrets) with the hub or between them. This scenario aligns with the secure deployment of body area networks, IoT, medical devices, industrial automation sensors, autonomous vehicles, and others. We develop VERSE, a physical-layer group message integrity verification primitive that effectively detects advanced wireless signal manipulations that can be used to launch man-in-the-middle (MitM) attacks over wireless. Without using shared secrets to establish authenticated channels, such attacks are notoriously difficult to thwart and can undermine the authentication and key establishment processes. VERSE exploits the existence of multiple devices to verify the integrity of the messages exchanged within the group. We then use VERSE to build a bootstrapping protocol, which securely introduces new devices to the network. Compared to the state-of-the-art, VERSE achieves in-band message integrity verification during secure pairing using only the RF modality without relying on out-of-band channels or extensive human involvement. It guarantees security even when the adversary is capable of fully controlling the wireless channel by annihilating and injecting wireless signals. We study the limits of such advanced wireless attacks and prove that the introduction of multiple legitimate devices can be leveraged to increase the security of the pairing process. We validate our claims via theoretical analysis and extensive experimentations on the USRP platform. We further discuss various implementation aspects such as the effect of time synchronization between devices and the effects of multipath and interference. Note that the elimination of shared secrets, default passwords, and public key infrastructures effectively addresses the related key management challenges when these are considered at scale.

Alzahrani, A. A. K., Alfosail, M. K., Aldossary, M. M., Almuhaidib, M. M., Alqahtani, S. T., Saqib, N. A., Alissa, K. A., Almubairik, N. A..  2018.  Secure Sign: Signing Document Online. 2018 21st Saudi Computer Society National Computer Conference (NCC). :1–3.
The use of technology is increasing nowadays. On the other hand, most governments and legal offices still do not use technology to implement simple things such as signing a document because they still rely on face-to-face to ensure the authenticity of the signatory. Several challenges may come while signing documents online such as, how to authenticate the signing parties and how to ensure that signing parties will not deny their signatures in future? These challenges are addressed by SecureSign system that attach the signatories' identity with their fingerprints. SecureSign was implemented in C\# and Microsoft SQL Server Management Studio, with integrating fingerprint reader and electronic signature tablet. The SecureSign system achieves the main security goals which are confidentiality, authentication, non-repudiation and integrity. It will have an impact on society and business environments positively as it will reduce fraud and forgery, and help in controlling the process of signing either in contracts or confidential papers. SecureSign have Successfully achieved confidentiality by encrypting data using AES algorithm, authentication by using user fingerprint, nonrepudiation by associating the user ID with his fingerprint, and integrity by embedding QR barcode within the document and hashing its content.
Janjua, K., Ali, W..  2018.  Enhanced Secure Mechanism for Virtual Machine Migration in Clouds. 2018 International Conference on Frontiers of Information Technology (FIT). :135–140.
Live VM migration is the most vulnerable process in cloud federations for DDOS attacks, loss of data integrity, confidentiality, unauthorized access and injection of malicious viruses on VM disk images. We have scrutinized following set of crucial security features which are; authorization, confidentiality, replay protection (accountability), integrity, mutual authentication and source non-repudiation (availability) to cater different threats and vulnerabilities during live VM migration. The investigated threats and vulnerabilities are catered and implemented in a proposed solution, presented in this paper. Six security features-authorization, confidentiality, replay protection, integrity, mutual authentication and source non-repudiation are focused and modular implementation has been done. Solution is validated in AVISPA tool in modules for threats for all the notorious security requirements and no outbreak were seen.
Detken, K., Jahnke, M., Humann, M., Rollgen, B..  2018.  Integrity and Non-Repudiation of VoIP Streams with TPM2.0 over Wi-Fi Networks. 2018 IEEE 4th International Symposium on Wireless Systems within the International Conferences on Intelligent Data Acquisition and Advanced Computing Systems (IDAACS-SWS). :82–87.
The complete digitization of telecommunications allows new attack scenarios, which have not been possible with legacy phone technologies before. The reason is that physical access to legacy phone technologies was necessary. Regarding internet-based communication like voice over the internet protocol (VoIP), which can be established between random nodes, eavesdropping can happen everywhere and much easier. Additionally, injection of undesirable communication like SPAM or SPIT in digital networks is simpler, too. Encryption is not sufficient because it is also necessary to know which participants are talking to each other. For that reason, the research project INTEGER has been started with the main goals of providing secure authentication and integrity of a VoIP communication by using a digital signature. The basis of this approach is the Trusted Platform Module (TPM) of the Trusted Computing Group (TCG) which works as a hardware-based trusted anchor. The TPM will be used inside of wireless IP devices with VoIP softphones. The question is if it is possible to fulfill the main goals of the project in wireless scenarios with Wi-Fi technologies. That is what this contribution aims to clarify.

Wang, S., Zhu, S., Zhang, Y..  2018.  Blockchain-Based Mutual Authentication Security Protocol for Distributed RFID Systems. 2018 IEEE Symposium on Computers and Communications (ISCC). :00074–00077.

Since radio frequency identification (RFID) technology has been used in various scenarios such as supply chain, access control system and credit card, tremendous efforts have been made to improve the authentication between tags and readers to prevent potential attacks. Though effective in certain circumstances, these existing methods usually require a server to maintain a database of identity related information for every tag, which makes the system vulnerable to the SQL injection attack and not suitable for distributed environment. To address these problems, we now propose a novel blockchain-based mutual authentication security protocol. In this new scheme, there is no need for the trusted third parties to provide security and privacy for the system. Authentication is executed as an unmodifiable transaction based on blockchain rather than database, which applies to distributed RFID systems with high security demand and relatively low real-time requirement. Analysis shows that our protocol is logically correct and can prevent multiple attacks.

Ahmed, Hamdi Abdurhman, Jang, Jong Wook.  2018.  Document Certificate Authentication System Using Digitally Signed QR Code Tag. Proceedings of the 12th International Conference on Ubiquitous Information Management and Communication. :65:1–65:5.
Now a day document such as Degree certificate can be easily forged fully or partially modifying obtained score result like GPA (Grade Point Average). Digital signature are used to detect unauthorized modification to data and to authenticate the identity of signatory. The Quick Response (QR) code was designed for storage information and high-speed readability. This paper proposed a method that QR code will contain a digital signature with the student data such as degree holder's name, major program, GPA obtained and more, which will be signed by Higher Educational Institute (HEI). In order to use this system, all HEI have to register in central system, the central system provide another system that will deploy in each HEI. All digitally signed certificate generating process are offline. To verify the digital signature signed with QR code, we developed specific smart phone application which will scan and authenticate the certificate without the need to address the certificate issuing institution and gaining access to user's security credentials.
Moon, J., Lee, Y., Yang, H., Song, T., Won, D..  2018.  Cryptanalysis of a privacy-preserving and provable user authentication scheme for wireless sensor networks based on Internet of Things security. 2018 International Conference on Information Networking (ICOIN). :432–437.
User authentication in wireless sensor networks is more complex than normal networks due to sensor network characteristics such as unmanned operation, limited resources, and unreliable communication. For this reason, various authentication protocols have been presented to provide secure and efficient communication. In 2017, Wu et al. presented a provable and privacy-preserving user authentication protocol for wireless sensor networks. Unfortunately, we found that Wu et al.'s protocol was still vulnerable against user impersonation attack, and had a problem in the password change phase. We show how an attacker can impersonate an other user and why the password change phase is ineffective.
Duan, Li, Li, Yong, Liao, Lijun.  2018.  Flexible Certificate Revocation List for Efficient Authentication in IoT. Proceedings of the 8th International Conference on the Internet of Things. :7:1–7:8.

When relying on public key infrastructure (PKI) for authentication, whether a party can be trusted primarily depends on its certificate status. Bob's certificate status can be retrieved by Alice through her interaction with Certificate Authority (CA) in the PKI. More specifically, Alice can download Certificate Revocation List (CRL) and then check whether the serial number of the Bob's certificate appears in this list. If not found, Alice knows that Bob can be trusted. Once downloaded, a CRL can be used offline for arbitrary many times till it expires, which saves the bandwidth to an extreme. However, if the number of revoked certificates becomes too large, the size of the CRL will exceed the RAM of Alice's device. This conflict between bandwidth and RAM consumption becomes even more challenging for the Internet-of-Things (IoT), since the IoT end-devices is usually constrained by both factors. To solve this problem in PKI-based authentication in IoT, we proposed two novel lightweight CRL protocols with maximum flexibility tailored for constrained IoT end-devices. The first one is based on generalized Merkle hash tree and the second is based on Bloom filter. We also provided quantitative theorems for CRL parameter configuration, which help strike perfect balance among bandwidth, RAM usage and security in various practical IoT scenarios. Furthermore, we thoroughly evaluated the proposed CRL protocols and exhibited their outstanding efficiency in terms of RAM and bandwidth consumption. In addition, our formal treatment of the security of a CRL protocol can also be of independent interest.

The target of security protection of the power distribution automation system (the distribution system for short) is to ensure the security of communication between the distribution terminal (terminal for short) and the distribution master station (master system for short). The encryption and authentication gateway (VPN gateway for short) for distribution system enhances the network layer communication security between the terminal and the VPN gateway. The distribution application layer encryption authentication device (master cipher machine for short) ensures the confidentiality and integrity of data transmission in application layer, and realizes the identity authentication between the master station and the terminal. All these measures are used to prevent malicious damage and attack to the master system by forging terminal identity, replay attack and other illegal operations, in order to prevent the resulting distribution network system accidents. Based on the security protection scheme of the power distribution automation system, this paper carries out the development of multi-chip encapsulation, develops IPSec Protocols software within the security chip, and realizes dual encryption and authentication function in IP layer and application layer supporting the national cryptographic algorithm.

Blockchain normalizes applications that run on the internet through the standardization of decentralized data structure, computational requirements and trust in transactions. This new standard has now spawned hundreds of legitimate internet applications in addition to the cryptocurrency revolution. This next frontier that standardizes internet applications will dramatically increase productivity to levels never seen before, especially when applied to Internet of Things (IoT) applications. The blockchain framework relies on cryptographic private keys to sign digital data as its foundational principle. Without the security of private keys to sign data blocks, there can be no trust in blockchain. Central storage of these keys for managing IoT machines and users, while convenient to implement, will be highly detrimental to the assumed safety and security of this next frontier. In this paper, we will introduce decentralized and device agnostic cryptographic signing solutions suitable for securing users and machines in blockchain and IoT applications.

Anomaly detection on security logs is receiving more and more attention. Authentication events are an important component of security logs, and being able to produce trustful and accurate predictions minimizes the effort of cyber-experts to stop false attacks. Observed events are classified into Normal, for legitimate user behavior, and Malicious, for malevolent actions. These classes are consistently excessively imbalanced which makes the classification problem harder; in the commonly used Los Alamos dataset, the malicious class comprises only 0.00033% of the total. This work proposes a novel method to extract advanced composite features, and a supervised learning technique for classifying authentication logs trustfully; the models are Random Forest, LogitBoost, Logistic Regression, and ultimately Majority Voting which leverages the predictions of the previous models and gives the final prediction for each authentication event. We measure the performance of our experiments by using the False Negative Rate and False Positive Rate. In overall we achieve 0 False Negative Rate (i.e. no attack was missed), and on average a False Positive Rate of 0.0019.

Cho, Joo Yeon, Szyrkowiec, Thomas.  2018.  Practical Authentication and Access Control for Software-Defined Networking over Optical Networks. Proceedings of the 2018 Workshop on Security in Softwarized Networks: Prospects and Challenges. :8-13.

A framework of Software-Defined Networking (SDN) provides a centralized and integrated method to manage and control modern optical networks. Unfortunately, the centralized and programmable structure of SDN introduces several new security threats, which may allow an adversary to take over the entire operation of the network. In this paper, we investigate the potential security threats of SDN over optical networks and propose a mutual authentication and a fine-grained access control mechanism, which are essential to avoid an unauthorized access to the network. The proposed schemes are based only on cryptographic hash functions and do not require an installation of the complicated cryptographic library such as SSL. Unlike conventional authentication and access control schemes, the proposed schemes are flexible, compact and, in addition, are resistant to quantum computer attacks, which may become critical in the near future.

This computer era leads human to interact with computers and networks but there is no such solution to get rid of security problems. Securities threats misleads internet, we are sometimes losing our hope and reliability with many server based access. Even though many more crypto algorithms are coming for integrity and authentic data in computer access still there is a non reliable threat penetrates inconsistent vulnerabilities in networks. These vulnerable sites are taking control over the user's computer and doing harmful actions without user's privileges. Though Firewalls and protocols may support our browsers via setting certain rules, still our system couldn't support for data reliability and confidentiality. Since these problems are based on network access, lets we consider TCP/IP parameters as a dataset for analysis. By doing preprocess of TCP/IP packets we can build sovereign model on data set and clump cluster. Further the data set gets classified into regular traffic pattern and anonymous pattern using KNN classification algorithm. Based on obtained pattern for normal and threats data sets, security devices and system will set rules and guidelines to learn by it to take needed stroke. This paper analysis the computer to learn security actions from the given data sets which already exist in the previous happens.

Hmouda, E., Li, W..  2018.  Detection and Prevention of Attacks in MANETs by Improving the EAACK Protocol. SoutheastCon 2018. :1–7.

Mobile Ad Hoc Networks are dynamic in nature and have no rigid or reliable network infrastructure by their very definition. They are expected to be self-governed and have dynamic wireless links which are not entirely reliable in terms of connectivity and security. Several factors could cause their degradation, such as attacks by malicious and selfish nodes which result in data carrying packets being dropped which in turn could cause breaks in communication between nodes in the network. This paper aims to address the issue of remedy and mitigation of the damage caused by packet drops. We proposed an improvement on the EAACK protocol to reduce the network overhead packet delivery ratio by using hybrid cryptography techniques DES due to its higher efficiency in block encryption, and RSA due to its management in key cipher. Comparing to the existing approaches, our simulated results show that hybrid cryptography techniques provide higher malicious behavior detection rates, and improve the performance. This research can also lead to more future efforts in using hybrid encryption based authentication techniques for attack detection/prevention in MANETs.

Sutradhar, M. R., Sultana, N., Dey, H., Arif, H..  2018.  A New Version of Kerberos Authentication Protocol Using ECC and Threshold Cryptography for Cloud Security. 2018 Joint 7th International Conference on Informatics, Electronics Vision (ICIEV) and 2018 2nd International Conference on Imaging, Vision Pattern Recognition (icIVPR). :239–244.

Dependency on cloud computing are increasing day by day due to its beneficial aspects. As day by day we are relying on cloud computing, the securities issues are coming up. There are lots of security protocols but now-a-days those protocol are not secured enough to provide a high security. One of those protocols which were once highly secured, is Kerberos authentication protocol. With the advancement of technology, Kerberos authentication protocol is no longer as secured as it was before. Many authors have thought about the improvement of Kerberos authentication protocol and consequently they have proposed different types of protocol models by using a renowned public key cryptography named RSA cryptography. Though RSA cryptography is good to some extent but this cryptography has some flaws that make this cryptography less secured as well as less efficient. In this paper, we are combining Elliptic Curve Cryptography (ECC) as well as Threshold Cryptography to create a new version of Kerberos authentication protocol. Our proposed model will provide secure transaction of data which will not only be hard to break but also increase memory efficiency, cost efficiency, and reduce the burden of computation.

Dey, H., Islam, R., Arif, H..  2019.  An Integrated Model To Make Cloud Authentication And Multi-Tenancy More Secure. 2019 International Conference on Robotics,Electrical and Signal Processing Techniques (ICREST). :502–506.

Cloud Computing is an important term of modern technology. The usefulness of Cloud is increasing day by day and simultaneously more and more security problems are arising as well. Two of the major threats of Cloud are improper authentication and multi-tenancy. According to the specialists both pros and cons belong to multi-tenancy. There are security protocols available but it is difficult to claim these protocols are perfect and ensure complete protection. The purpose of this paper is to propose an integrated model to ensure better Cloud security for Authentication and multi-tenancy. Multi-tenancy means sharing of resources and virtualization among clients. Since multi-tenancy allows multiple users to access same resources simultaneously, there is high probability of accessing confidential data without proper privileges. Our model includes Kerberos authentication protocol to enhance authentication security. During our research on Kerberos we have found some flaws in terms of encryption method which have been mentioned in couple of IEEE conference papers. Pondering about this complication we have elected Elliptic Curve Cryptography. On the other hand, to attenuate arose risks due to multi-tenancy we are proposing a Resource Allocation Manager Unit, a Control Database and Resource Allocation Map. This part of the model will perpetuate resource allocation for the users.

Prabha, K. M., Saraswathi, D. P. Vidhya.  2018.  TIGER HASH KERBEROS BIOMETRIC BLOWFISH USER AUTHENTICATION FOR SECURED DATA ACCESS IN CLOUD. 2018 2nd International Conference on 2018 2nd International Conference on I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC)I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC). :145–151.

Cloud computing is a standard architecture for providing computing services among servers and cloud user (CU) for preserving data from unauthorized users. Therefore, the user authentication is more reliable to ensure cloud services accessed only by a genuine user. To improve the authentication accuracy, Tiger Hash-based Kerberos Biometric Blowfish Authentication (TH-KBBA) Mechanism is introduced for accessing data from server. It comprises three steps, namely Registration, Authentication and Ticket Granting. In the Registration process, client enrolls user details and stores on cloud server (CS) using tiger hashing function. User ID and password is given by CS after registration. When client wants to access data from CS, authentication server (AS) verifies user identity by sending a message. When authenticity is verified, AS accepts user as authenticated user and convinces CS that user is authentic. For convincing process, AS generates a ticket and encrypted using Blowfish encryption. Encrypted ticket is sent back to user. Then, CU sends message to server containing users ID and encrypted ticket. Finally, the server decrypts ticket using blowfish decryption and verifies the user ID. If these two ID gets matched, the CS grants requested data to the user. Experimental evaluation of TH-KBBA mechanism and existing methods are carried out with different factors such as Authentication accuracy, authentications time and confidentiality rate with respect to a number of CUs and data.

Kurera, C., Navoda, D..  2018.  Node-to-Node Secure Data Transmission Protocol for Low-power IoT Devices. 2018 18th International Conference on Advances in ICT for Emerging Regions (ICTer). :1–7.

Through the internet and local networks, IoT devices exchange data. Most of the IoT devices are low-power devices, meaning that they are designed to use less electric power. To secure data transmission, it is required to encrypt the messages. Encryption and decryption of messages are computationally expensive activities, thus require considerable amount of processing and memory power which is not affordable to low-power IoT devices. Therefore, not all secure transmission protocols are low-power IoT devices friendly. This study proposes a secure data transmission protocol for low-power IoT devices. The design inherits some features in Kerberos and onetime password concepts. The protocol is designed for devices which are connected to each other, as in a fully connected network topology. The protocol uses symmetric key cryptography under the assumption of that the device specific keys are never being transmitted over the network. It resists DoS, message replay and Man-of-the-middle attacks while facilitating the key security concepts such as Authenticity, Confidentiality and Integrity. The designed protocol uses less number of encryption/decryption cycles and maintain session based strong authentication to facilitate secure data transmission among nodes.

F, A. K., Mhaibes, H. Imad.  2018.  A New Initial Authentication Scheme for Kerberos 5 Based on Biometric Data and Virtual Password. 2018 International Conference on Advanced Science and Engineering (ICOASE). :280–285.

Kerberos is a third party and widely used authentication protocol, in which it enables computers to connect securely using a single sign-on over an insecure channel. It proves the identity of clients and encrypts all the communications between them to ensure data privacy and integrity. Typically, Kerberos composes of three communication phases to establish a secure session between any two clients. The authentication is based on a password-based scheme, in which it is a secret long-term key shared between the client and the Kerberos. Therefore, Kerberos suffers from a password-guessing attack, the main drawback of Kerberos. In this paper, we overcome this limitation by modifying the first initial phase using the virtual password and biometric data. In addition, the proposed protocol provides a strong authentication scenario against multiple types of attacks.

Ma, Y., Ning, H..  2018.  The improvement of wireless LAN security authentication mechanism based on Kerberos. 2018 International Conference on Electronics Technology (ICET). :392–397.

In order to solve the problem of vulnerable password guessing attacks caused by dictionary attacks, replay attacks in the authentication process, and man-in-the-middle attacks in the existing wireless local area network in terms of security authentication, we make some improvements to the 802.1X / EAP authentication protocol based on the study of the current IEEE802.11i security protocol with high security. After introducing the idea of Kerberos protocol authentication and applying the idea in the authentication process of 802.1X / EAP, a new protocol of Kerberos extensible authentication protocol (KEAP) is proposed. Firstly, the protocol introduces an asymmetric key encryption method, uses public key encryption during data transmission, and the receiver uses the corresponding private key for decryption. With unidirectional characteristics and high security, the encryption can avoid password guessing attacks caused by dictionary attacks as much as possible. Secondly, aiming at the problem that the request message sent from the client to the authentication server is vulnerable to replay attacks, the protocol uses a combination of the message sequence number and the random number, and the message serial number is added to the request message sent from the client to the authentication server. And establish a list database for storing message serial number and random number in the authentication server. After receiving a transfer message, the serial number and the random number are extracted and compared with the values in the list database to distinguish whether it is a retransmission message. Finally, the protocol introduces a keychain mechanism and uses an irreversible Hash function to encrypt the final authentication result, thereby effectively solving the man-in-the-middle attack by the pretender. The experiment uses the OPNET 14.5 simulation platform to model the KEAP protocol and simulate simulation attacks, and compares it with the current more common EAP-TLS authentication protocol. Experimental results show that the average traffic of the KEAP protocol is at least 14.74% higher than the EAP-TLS authentication protocol, and the average bit error rate is reduced by at least 24.00%.

This paper presents a novel research model of identity and the use of this model to answer some interesting research questions. Information travels in the cyber world, not only bringing us convenience and prosperity but also jeopardy. Protecting this information has been a commonly discussed issue in recent years. One type of this information is Personally Identifiable Information (PII), often used to perform personal authentication. People often give PIIs to organizations, e.g., when applying for a new job or filling out a new application on a website. While the use of such PII might be necessary for authentication, giving PII increases the risk of its exposure to criminals. We introduce two innovative approaches based on our model of identity to help evaluate and find an optimal set of PIIs that satisfy authentication purposes but minimize risk of exposure. Our model paves the way for more informed selection of PIIs by organizations that collect them as well as by users who offer PIIs to these organizations.
Celia, L., Cungang, Y..  2018.  (WIP) Authenticated Key Management Protocols for Internet of Things. 2018 IEEE International Congress on Internet of Things (ICIOT). :126–129.

The Internet of Things (IoT) provides transparent and seamless incorporation of heterogeneous and different end systems. It has been widely used in many applications such as smart homes. However, people may resist the IOT as long as there is no public confidence that it will not cause any serious threats to their privacy. Effective secure key management for things authentication is the prerequisite of security operations. In this paper, we present an interactive key management protocol and a non-interactive key management protocol to minimize the communication cost of the things. The security analysis show that the proposed schemes are resilient to various types of attacks.

In this paper, we consider ways of organizing group authentication, as well as the features of constructing the isogeny of elliptic curves. The work includes the study of isogeny graphs and their application in postquantum systems. A hierarchical group authentication scheme has been developed using transformations based on the search for isogeny of elliptic curves.

Lu, X., Wan, X., Xiao, L., Tang, Y., Zhuang, W..  2018.  Learning-Based Rogue Edge Detection in VANETs with Ambient Radio Signals. 2018 IEEE International Conference on Communications (ICC). :1-6.
Edge computing for mobile devices in vehicular ad hoc networks (VANETs) has to address rogue edge attacks, in which a rogue edge node claims to be the serving edge in the vehicle to steal user secrets and help launch other attacks such as man-in-the-middle attacks. Rogue edge detection in VANETs is more challenging than the spoofing detection in indoor wireless networks due to the high mobility of onboard units (OBUs) and the large-scale network infrastructure with roadside units (RSUs). In this paper, we propose a physical (PHY)- layer rogue edge detection scheme for VANETs according to the shared ambient radio signals observed during the same moving trace of the mobile device and the serving edge in the same vehicle. In this scheme, the edge node under test has to send the physical properties of the ambient radio signals, including the received signal strength indicator (RSSI) of the ambient signals with the corresponding source media access control (MAC) address during a given time slot. The mobile device can choose to compare the received ambient signal properties and its own record or apply the RSSI of the received signals to detect rogue edge attacks, and determines test threshold in the detection. We adopt a reinforcement learning technique to enable the mobile device to achieve the optimal detection policy in the dynamic VANET without being aware of the VANET model and the attack model. Simulation results show that the Q-learning based detection scheme can significantly reduce the detection error rate and increase the utility compared with existing schemes.
