Krohmer, D., Schotten, H. D..  2020.  Decentralized Identifier Distribution for Moving Target Defense and Beyond. 2020 International Conference on Cyber Situational Awareness, Data Analytics and Assessment (CyberSA). :1—8.

In this work, we propose a novel approach for decentralized identifier distribution and synchronization in networks. The protocol generates network entity identifiers composed of timestamps and cryptographically secure random values with a significant reduction of collision probability. The distribution is inspired by Unique Universal Identifiers and Timestamp-based Concurrency Control algorithms originating from database applications. We defined fundamental requirements for the distribution, including: uniqueness, accuracy of distribution, optimal timing behavior, scalability, small impact on network load for different operation modes and overall compliance to common network security objectives. An implementation of the proposed approach is evaluated and the results are presented. Originally designed for a domain of proactive defense strategies known as Moving Target Defense, the general architecture of the protocol enables arbitrary applications where identifier distributions in networks have to be decentralized, rapid and secure.

The presence of security vulnerabilities in automotive networks has already been shown by various publications in recent years. Due to the specification of the Controller Area Network (CAN) as a broadcast medium without security mechanisms, attackers are able to read transmitted messages without being noticed and to inject malicious messages. In order to detect potential attackers within a network or software system as early as possible, Intrusion Detection Systems (IDSs) are prevalent. Many approaches for vehicles are based on techniques which are able to detect deviations from specified CAN network behaviour regarding protocol or payload properties. However, it is challenging to detect attackers who secretly connect to CAN networks and do not actively participate in bus traffic. In this paper, we present an approach that is capable of successfully detecting unknown CAN devices and determining the distance (cable length) between the attacker device and our sensing unit based on Time Domain Reflectometry (TDR) technique. We evaluated our approach on a real vehicle network.
Babkin, Sergey, Epishkina, Anna.  2019.  Authentication Protocols Based on One-Time Passwords. 2019 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus). :1794–1798.
Nowadays one-time passwords are used in a lot of areas of information technologies including e-commerce. A few vulnerabilities in authentication protocols based on one-time passwords are widely known. In current work, we analyze authentication protocols based on one-time passwords and their vulnerabilities. Both simple and complicated protocols which are implementing cryptographic algorithms are reviewed. For example, an analysis of relatively old Lamport's hash-chain protocol is provided. At the same time, we examine HOTP and TOTP protocols which are actively used nowadays. The main result of the work are conclusions about the security of reviewed protocols based on one-time passwords.

Jain, Jay Kumar, Chauhan, Dipti.  2019.  Analytical Study on Mobile Ad Hoc Networks for IPV6. 2019 4th International Conference on Internet of Things: Smart Innovation and Usages (IoT-SIU). :1–6.
The ongoing progressions in wireless innovation have lead to the advancement of another remote framework called Mobile Ad hoc Networks. The Mobile Ad hoc Network is a self arranging system of wireless gadgets associated by wireless connections. The traditional protocol, for example, TCP/IP has restricted use in Mobile impromptu systems in light of the absence of portability and assets. This has lead to the improvement of many steering conventions, for example, proactive, receptive and half breed. One intriguing examination zone in MANET is steering. Steering in the MANETs is a testing assignment and has gotten a colossal measure of consideration from examines. An uncommon consideration is paid on to feature the combination of MANET with the critical highlights of IPv6, for example, coordinated security, start to finish correspondence. This has prompted advancement of various directing conventions for MANETs, and every creator of each developed convention contends that the technique proposed gives an improvement over various distinctive systems considered in the writing for a given system situation. In this way, it is very hard to figure out which conventions may perform best under various diverse system situations, for example, expanding hub thickness and traffic. In this paper, we give the ongoing expository investigation on MANETs for IPV6 systems.
Eugster, P., Marson, G. A., Poettering, B..  2018.  A Cryptographic Look at Multi-party Channels. 2018 IEEE 31st Computer Security Foundations Symposium (CSF). :31–45.
Cryptographic channels aim to enable authenticated and confidential communication over the Internet. The general understanding seems to be that providing security in the sense of authenticated encryption for every (unidirectional) point-to-point link suffices to achieve this goal. As recently shown (in FSE17/ToSC17), however, the security properties of the unidirectional links do not extend, in general, to the bidirectional channel as a whole. Intuitively, the reason for this is that the increased interaction in bidirectional communication can be exploited by an adversary. The same applies, a fortiori, in a multi-party setting where several users operate concurrently and the communication develops in more directions. In the cryptographic literature, however, the targeted goals for group communication in terms of channel security are still unexplored. Applying the methodology of provable security, we fill this gap by defining exact (game-based) authenticity and confidentiality goals for broadcast communication, and showing how to achieve them. Importantly, our security notions also account for the causal dependencies between exchanged messages, thus naturally extending the bidirectional case where causal relationships are automatically captured by preserving the sending order. On the constructive side we propose a modular and yet efficient protocol that, assuming only point-to-point links between users, leverages (non-cryptographic) broadcast and standard cryptographic primitives to a full-fledged broadcast channel that provably meets the security notions we put forth.

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.

Mobile Ad-hoc Network (MANET) is a prominent technology in the wireless networking field in which the movables nodes operates in distributed manner and collaborates with each other in order to provide the multi-hop communication between the source and destination nodes. Generally, the main assumption considered in the MANET is that each node is trusted node. However, in the real scenario, there are some unreliable nodes which perform black hole attack in which the misbehaving nodes attract all the traffic towards itself by giving false information of having the minimum path towards the destination with a very high destination sequence number and drops all the data packets. In the paper, we have presented different categories for black hole attack mitigation techniques and also presented the summary of various techniques along with its drawbacks that need to be considered while designing an efficient protocol.

Antignac, Thibaud, Mukelabai, Mukelabai, Schneider, Gerardo.  2017.  Specification, Design, and Verification of an Accountability-aware Surveillance Protocol. Proceedings of the Symposium on Applied Computing. :1372–1378.

Though controversial, surveillance activities are more and more performed for security reasons. However, such activities are extremely privacy-intrusive. This is seen as a necessary side-effect to ensure the success of such operations. In this paper, we propose an accountability-aware protocol designed for surveillance purposes. It relies on a strong incentive for a surveillance organisation to register its activity to a data protection authority. We first elicit a list of account-ability requirements, we provide an architecture showing the interaction of the different involved parties, and we propose an accountability-aware protocol which is formally specified in the applied pi calculus. We use the ProVerif tool to automatically verify that the protocol respects confidentiality, integrity and authentication properties.

Schiavone, E., Ceccarelli, A., Bondavalli, A..  2017.  Continuous Biometric Verification for Non-Repudiation of Remote Services. Proceedings of the 12th International Conference on Availability, Reliability and Security. :4:1–4:10.
As our society massively relies on ICT, security services are becoming essential to protect users and entities involved. Amongst such services, non-repudiation provides evidences of actions, protects against their denial, and helps solving disputes between parties. For example, it prevents denial of past behaviors as having sent or received messages. Noteworthy, if the information flow is continuous, evidences should be produced for the entirety of the flow and not only at specific points. Further, non-repudiation should be guaranteed by mechanisms that do not reduce the usability of the system or application. To meet these challenges, in this paper, we propose two solutions for non-repudiation of remote services based on multi-biometric continuous authentication. We present an application scenario that discusses how users and service providers are protected with such solutions. We also discuss the technological readiness of biometrics for non-repudiation services: the outcome is that, under specific assumptions, it is actually ready.
Andy, S., Rahardjo, B., Hanindhito, B..  2017.  Attack scenarios and security analysis of MQTT communication protocol in IoT system. 2017 4th International Conference on Electrical Engineering, Computer Science and Informatics (EECSI). :1–6.
Various communication protocols are currently used in the Internet of Things (IoT) devices. One of the protocols that are already standardized by ISO is MQTT protocol (ISO / IEC 20922: 2016). Many IoT developers use this protocol because of its minimal bandwidth requirement and low memory consumption. Sometimes, IoT device sends confidential data that should only be accessed by authorized people or devices. Unfortunately, the MQTT protocol only provides authentication for the security mechanism which, by default, does not encrypt the data in transit thus data privacy, authentication, and data integrity become problems in MQTT implementation. This paper discusses several reasons on why there are many IoT system that does not implement adequate security mechanism. Next, it also demonstrates and analyzes how we can attack this protocol easily using several attack scenarios. Finally, after the vulnerabilities of this protocol have been examined, we can improve our security awareness especially in MQTT protocol and then implement security mechanism in our MQTT system to prevent such attack.

In smart factories and smart homes, devices such as smart sensors are connected to the Internet. Independent of the context in which such a smart sensor is deployed, the possibility to change its configuration parameters in a secure way is essential. Existing solutions do provide only minimal security or do not allow to transfer arbitrary configuration data. In this paper, we present an NFC- and QR-code based configuration interface for smart sensors which improves the security and practicability of the configuration altering process while introducing as little overhead as possible. We present a protocol for configuration as well as a hardware extension including a dedicated security controller (SC) for smart sensors. For customers, no additional hardware other than a commercially available smartphone will be necessary which makes the proposed approach highly applicable for smart factory and smart home contexts alike.

Radio Frequency IDentification(RFID) is one of the most important sensing techniques for Internet of Things(IoT) and RFID systems have been applied to various different fields. But an RFID system usually uses open wireless radio wave to communicate and this will lead to a serious threat to its privacy and security. The current popular RFID tags are some low-cost passive tags. Their computation and storage resources are very limited. It is not feasible for them to complete some complicated cryptographic operations. So it is very difficult to protect the security and privacy of an RFID system. Lightweight authentication protocol is considered as an effective approach. Many typical authentication protocols usually use Hash functions so that they require more computation and storage resources. Based on CRC function, we propose a lightweight RFID authentication protocol, which needs less computation and storage resources than Hash functions. This protocol exploits an on-chip CRC function and a pseudorandom number generator to ensure the anonymity and freshness of communications between reader and tag. It provides forward security and confidential communication. It can prevent eavesdropping, location trace, replay attack, spoofing and DOS-attack effectively. It is very suitable to be applied to RFID systems.

Bing, Y., Baolong, L., Hua, C..  2017.  Review on RFID Identity Authentication Protocols Based on Hash Function. 2017 International Conference on Computer Network, Electronic and Automation (ICCNEA). :20–27.

Radio frequency identification (RFID) is one of the key technologies of Internet of Things, which have many security issues in an open environment. In order to solve the communication problem between RFID tags and readers, security protocols has been improved constantly as the first choice. But the form of attack is also changing constantly with the development of technology. In this paper we classify the security protocols and introduce some problems in the recent security protocols.

Fournet, Cédric.  2016.  Verified Secure Implementations for the HTTPS Ecosystem: Invited Talk. Proceedings of the 2016 ACM Workshop on Programming Languages and Analysis for Security. :89–89.

The HTTPS ecosystem, including the SSL/TLS protocol, the X.509 public-key infrastructure, and their cryptographic libraries, is the standardized foundation of Internet Security. Despite 20 years of progress and extensions, however, its practical security remains controversial, as witnessed by recent efforts to improve its design and implementations, as well as recent disclosures of attacks against its deployments. The Everest project is a collaboration between Microsoft Research, INRIA, and the community at large that aims at modelling, programming, and verifying the main HTTPS components with strong machine-checked security guarantees, down to core system and cryptographic assumptions. Although HTTPS involves a relatively small amount of code, it requires efficient low-level programming and intricate proofs of functional correctness and security. To this end, we are also improving our verifications tools (F*, Dafny, Lean, Z3) and developing new ones. In my talk, I will present our project, review our experience with miTLS, a verified reference implementation of TLS coded in F*, and describe current work towards verified, secure, efficient HTTPS.

Li, Gaochao, Xu, Xiaolin, Li, Qingshan.  2015.  LADP: A lightweight authentication and delegation protocol for RFID tags. 2015 Seventh International Conference on Ubiquitous and Future Networks. :860–865.

In recent years, the issues of RFID security and privacy are a concern. To prevent the tag is cloned, physically unclonable function (PUF) has been proposed. In each PUF-enabled tag, the responses of PUF depend on the structural disorder that cannot be cloned or reproduced. Therefore, many responses need to store in the database in the initial phase of many authentication protocols. In the supply chain, the owners of the PUF-enabled Tags change frequently, many authentication and delegation protocols are proposed. In this paper, a new lightweight authentication and delegation protocol for RFID tags (LADP) is proposed. The new protocol does not require pre-stored many PUF's responses in the database. When the authentication messages are exchanged, the next response of PUF is passed to the reader secretly. In the transfer process of ownership, the new owner will not get the information of the interaction of the original owner. It can protect the privacy of the original owner. Meanwhile, the original owner cannot continue to access or track the tag. It can protect the privacy of the new owner. In terms of efficiency, the new protocol replaces the pseudorandom number generator with the randomness of PUF that suitable for use in the low-cost tags. The cost of computation and communication are reduced and superior to other protocols.

Networked systems have adapted Radio Frequency identification technology (RFID) to automate their business process. The Networked RFID Systems (NRS) has some unique characteristics which raise new privacy and security concerns for organizations and their NRS systems. The businesses are always having new realization of business needs using NRS. One of the most recent business realization of NRS implementation on large scale distributed systems (such as Internet of Things (IoT), supply chain) is to ensure visibility and traceability of the object throughout the chain. However, this requires assurance of security and privacy to ensure lawful business operation. In this paper, we are proposing a secure tracker protocol that will ensure not only visibility and traceability of the object but also genuineness of the object and its travel path on-site. The proposed protocol is using Physically Unclonable Function (PUF), Diffie-Hellman algorithm and simple cryptographic primitives to protect privacy of the partners, injection of fake objects, non-repudiation, and unclonability. The tag only performs a simple mathematical computation (such as combination, PUF and division) that makes the proposed protocol suitable to passive tags. To verify our security claims, we performed experiment on Security Protocol Description Language (SPDL) model of the proposed protocol using automated claim verification tool Scyther. Our experiment not only verified our claims but also helped us to eliminate possible attacks identified by Scyther.

The ownership transfer of RFID tag means a tagged product changes control over the supply chain. Recently, Doss et al. proposed two secure RFID tag ownership transfer (RFID-OT) protocols based on quadratic residues. However, we find that they are vulnerable to the desynchronization attack. The attack is probabilistic. As the parameters in the protocols are adopted, the successful probability is 93.75%. We also show that the use of the pseudonym of the tag h(TID) and the new secret key KTID are not feasible. In order to solve these problems, we propose the improved schemes. Security analysis shows that the new protocols can resist in the desynchronization attack and other attacks. By optimizing the performance of the new protocols, it is more practical and feasible in the large-scale deployment of RFID tags.

M. Moradi, F. Qian, Q. Xu, Z. M. Mao, D. Bethea, M. K. Reiter.  2015.  "Caesar: high-speed and memory-efficient forwarding engine for future internet architecture". 2015 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS). :171-182.

In response to the critical challenges of the current Internet architecture and its protocols, a set of so-called clean slate designs has been proposed. Common among them is an addressing scheme that separates location and identity with self-certifying, flat and non-aggregatable address components. Each component is long, reaching a few kilobits, and would consume an amount of fast memory in data plane devices (e.g., routers) that is far beyond existing capacities. To address this challenge, we present Caesar, a high-speed and length-agnostic forwarding engine for future border routers, performing most of the lookups within three fast memory accesses. To compress forwarding states, Caesar constructs scalable and reliable Bloom filters in Ternary Content Addressable Memory (TCAM). To guarantee correctness, Caesar detects false positives at high speed and develops a blacklisting approach to handling them. In addition, we optimize our design by introducing a hashing scheme that reduces the number of hash computations from k to log(k) per lookup based on hash coding theory. We handle routing updates while keeping filters highly utilized in address removals. We perform extensive analysis and simulations using real traffic and routing traces to demonstrate the benefits of our design. Our evaluation shows that Caesar is more energy-efficient and less expensive (in terms of total cost) compared to optimized IPv6 TCAM-based solutions by up to 67% and 43% respectively. In addition, the total cost of our design is approximately the same for various address lengths.

Emfinger, W., Karsai, G..  2015.  Modeling Network Medium Access Protocols for Network Quality of Service Analysis. Real-Time Distributed Computing (ISORC), 2015 IEEE 18th International Symposium on. :292-295.

Design-time analysis and verification of distributed real-time embedded systems necessitates the modeling of the time-varying performance of the network and comparing that to application requirements. Earlier work has shown how to build a system network model that abstracted away the network's physical medium and protocols which govern its access and multiplexing. In this work we show how to apply a network medium channel access protocol, such as Time-Division Multiple Access (TDMA), to our network analysis methods and use the results to show that the abstracted model without the explicit model of the protocol is valid.

Gandino, F., Montrucchio, B., Rebaudengo, M..  2014.  Key Management for Static Wireless Sensor Networks With Node Adding. Industrial Informatics, IEEE Transactions on. 10:1133-1143.

Wireless sensor networks offer benefits in several applications but are vulnerable to various security threats, such as eavesdropping and hardware tampering. In order to reach secure communications among nodes, many approaches employ symmetric encryption. Several key management schemes have been proposed in order to establish symmetric keys. The paper presents an innovative key management scheme called random seed distribution with transitory master key, which adopts the random distribution of secret material and a transitory master key used to generate pairwise keys. The proposed approach addresses the main drawbacks of the previous approaches based on these techniques. Moreover, it overperforms the state-of-the-art protocols by providing always a high security level.

Bande, V., Pop, S., Pitica, D..  2014.  Smart diagnose procedure for data acquisition systems inside dams. Design and Technology in Electronic Packaging (SIITME), 2014 IEEE 20th International Symposium for. :179-182.

This scientific paper reveals an intelligent system for data acquisition for dam monitoring and diagnose. This system is built around the RS485 communication standard and uses its own communication protocol [2]. The aim of the system is to monitor all signal levels inside the communication bus, respectively to detect the out of action data loggers. The diagnose test extracts the following functional parameters: supply voltage and the absolute value and common mode value for differential signals used in data transmission (denoted with “A” and “B”). Analyzing this acquired information, it's possible to find short-circuits or open-circuits across the communication bus. The measurement and signal processing functions, for flaws, are implemented inside the system's central processing unit. The next testing step is finding the out of action data loggers and is being made by trying to communicate with every data logger inside the network. The lack of any response from a data logger is interpreted as an error and using the code of the data logger's microcontroller, it is possible to find its exact position inside the dam infrastructure. The novelty of this procedure is the fact that it completely automates the diagnose procedure, which, until now, was made visually by checking every data logger.

Gerdes, S., Bergmann, O., Bormann, C..  2014.  Delegated Authenticated Authorization for Constrained Environments. Network Protocols (ICNP), 2014 IEEE 22nd International Conference on. :654-659.

Smart objects are small devices with limited system resources, typically made to fulfill a single simple task. By connecting smart objects and thus forming an Internet of Things, the devices can interact with each other and their users and support a new range of applications. Due to the limitations of smart objects, common security mechanisms are not easily applicable. Small message sizes and the lack of processing power severely limit the devices' ability to perform cryptographic operations. This paper introduces a protocol for delegating client authentication and authorization in a constrained environment. The protocol describes how to establish a secure channel based on symmetric cryptography between resource-constrained nodes in a cross-domain setting. A resource-constrained node can use this protocol to delegate authentication of communication peers and management of authorization information to a trusted host with less severe limitations regarding processing power and memory.
