Abstract: In 2014, Choi proposed a security enhanced anonymous multi-server authenticated key agreement scheme using smart card and biometrics and claimed that their scheme could overcome all of security issues in Chuang-Chen’s scheme, such as impersonation attack, smart card loss attack, denial of service attack and perfect forward secrecy. Unfortunately, we discover that Choi’s proposed scheme is not only still vulnerable to smart card loss attack and lack of perfect forward secrecy, but also contains a flaw in design for authentication phase after our analysis in detail. In order to solve these security issues, we propose an enhanced secure anonymous authentication scheme with key agreement based on smart cards and biometrics for multi-server environments in this paper. According to our performance and security analysis, it can prove that our proposed scheme is more efficiency and security in comparison to previous schemes.

Abstract: The development of kinds of mobile device is a nonlinear but in a tremendous hopping way. The security of wireless LAN is far more important, and its mainly present protection is the WPA & WPA2 protocol which is a complex tough algorithm. This exploratory study shows that there is a security gap by the social human factors which are the weak passwords. Traditionally, brute force password attack is using the dictionary files that is aimless and extremely labor work. Now, we proposed 10 rule-based methods which are globally inclusive and culturally exclusive and prove the insecurity of WPA & WPA2 by 100 empirical and valuable real wireless encrypted packets of WPA & WPA2. The evidence shows that there is a 68% of cracking rate and then do the passwords patterns analysis as well.

Abstract: In data analysis, it is always a tough task to strike the balance between the privacy and the applicability of the data. Due to the demand for individual privacy, the data are being more or less obscured before being released or outsourced to avoid possible privacy leakage. This process is so called de-identification. To discuss a de-identification policy, the most important two aspects should be the re-identification risk and the information loss. In this paper, we introduce a novel policy searching method to efficiently find out proper de-identification policies according to acceptable re-identification risk while retaining the information resided in the data. With the UCI Machine Learning Repository as our real world dataset, the re-identification risk can therefore be able to reflect the true risk of the de-identified data under the de-identification policies. Moreover, using the proposed algorithm, one can then efficiently acquire policies with higher information entropy.

Abstract: In IoT/Cloud environments, to provide an efficient and flexible payment service is very important since the client/device may not have a large storage and computation capability to finish the payment process. In these environments, any thin client/device may issue a service request to the cloud. For the fast progress of smartphone systems, a smartphone can help the client/device to finish the payment process with the help of the carrier. Although the smart phone may have more storage and computation capability than the client/device, the computation ability is also restricted. In this paper, in order to provide an efficient payment and authentication service framework in the IOT/Cloud environments, we propose a secure and efficient smartphone payment scheme in IoT/Cloud environments. Our proposed scheme can satisfy the properties including low communication and computation cost, no time synchronization problem, unforgeability, non-repudiation, and integrity. Also our scheme can achieve the security requirements including mutual authentication, session key agreement, and preventing all various well-known attacks.

Abstract: A mobile ad hoc network (MANET) is composed of multiple wireless mobile devices in which an infrastructure less network with dynamic topology is built based on wireless communication technologies. Novel applications such as location-based services and personal communication Apps used by mobile users with handheld wireless devices utilize MANET environments. In consequence, communication anonymity and message security have become critical issues for MANET environments. In this study, a novel secure routing protocol with communication anonymity, named as Hash-based Anonymous Secure Routing (HASR) protocol, is proposed to support identity anonymity, location anonymity and route anonymity, and defend against major security threats such as replay attack, spoofing, route maintenance attack, and denial of service (DoS) attack. Security analyses show that HASR can achieve both communication anonymity and message security with efficient performance in MANET environments.

Abstract: Anonymous channels guaranteeing anonymity of senders such as Tor are effective for whistle-blowing and other privacy sensitive scenarios. However, there is a risk of being abused for illegal activities. As a countermeasure to illegal activities using an anonymous channel, it is natural to construct an accountable anonymous channel which can revoke anonymity of senders when an unlawful message was sent out from them. In this paper, we point out that an accountable anonymous channel THEMIS does not provide anonymity in a perfect way and there is a possibility that attackers can identify senders even if messages are not malicious. Feasibility of tracing senders is analyzed by using simulation. Moreover, we give a simple remedy of the flaw in THEMIS.

Abstract: Network systems are becoming the core components of technical information infrastructures. The protection of network systems from malicious attacks is an urgent priority in our society. However, considering that all security threats are very complicated, easily missed, and error-prone, dealing with network vulnerabilities has brought about enormous challenges to network management. Therefore, one reasonable solution for a risk analysis is delegating an analysis of a network system to third parties that have more professional knowledge regarding a risk analysis. Highly confidential data such as the network configuration and vulnerabilities, as well as each hosts, are needed when delegating a risk analysis to a third party. Such confidential data may cause information leakage if no protection is provided. In this paper, we proposed a risk analysis system based on a rule-based risk analysis method. The prototype system was developed using Fairplay MP, a secure multi-party computation system, and was evaluated for a small network environment.

Abstract: Distributed attacks have reportedly caused the most serious losses in the modern cyber environment. Thus, how to avoid and detect distributed attacks has become one of the most important topics in the cyber security community. Of many approaches for avoiding and detecting cyber-attacks, behavior-based method has been attracting great attentions from many researchers and developers. It is well known that, for behavior-based cyber-attack detections, the algorithm for extracting normal modes from historic traffic is critically important. In this paper, after the newest algorithms for extracting normal behavior mode from historic traffics are discussed, a novel algorithm is proposed. Its efficiency is examined by experiments using dark net traffic data.

Abstract: With the progress of information technology, the computer crimes are emerging in an endless stream. It is because of the user’s privacy should be protected, when the user submit a service request to the service provider, both of them should check the identity of the other, and then build a shared key to accomplish the service request. In this paper, we adopt the identity-based cryptosystem and the elliptic curve cryptosystem to design a privacy-preserved key agreement with user authentication. This protocol can achieve several properties: mutual authentication, deniability, and forward secrecy. Besides, the performance of the proposed protocol based on RSA is better than previous studies.

Abstract: Watermark-based copyright protection techniques have been investigated for more than two decades in the signal processing and the digital rights management communities. Most efforts have been devoted on hiding the watermark and increasing the robustness of the embedded watermark under common signal processing operations and geometric transformations. In this paper, we build our scheme based on these previous well developed signal processing techniques but focus on how to employ unpredictable signature-seeded pseudo random bit sequence to make the false negative watermark detection rate computationally negligible. The ultimate goal is to resolve the ownership dispute of an exhibited digital media under adversarial watermark removal attacks.

Abstract: In recent years people in modern societies have heavily relied on their own intelligent mobile devices such as smartphones and tablets to get personal services and improve work efficiency. In consequence, quick and simple authentication mechanisms along with energy saving consideration are generally adopted by these smart handheld devices such as screen auto-lock schemes. When a smart device activates its screen lock mode to protect user privacy and data security on this device, its screen auto-lock scheme will be executed at the same time. Device user can setup the length of time period to control when to activate the screen lock mode of a smart device. However, it causes inconvenience for device users when a short time period is set for invoking screen auto-lock. How to get balance between security and convenience for individual users to use their own smart devices has become an interesting issue. In this paper, an intelligent display (screen) auto-lock scheme is proposed for mobile users. It can dynamically adjust the unlock time period setting of an auto-lock scheme based on derived knowledge from past user behaviors.

Adachi, T.; Omote, K., “An Approach to Predict Drive-by-Download Attacks by Vulnerability Evaluation and Opcode,” in Information Security (AsiaJCIS), 2015 10th Asia Joint Conference on, vol., no., pp. 145–151, 24–26 May 2015. doi:10.1109/AsiaJCIS.2015.17
Abstract: Drive-by-download attacks exploit vulnerabilities in Web browsers, and users are unnoticeably downloading malware which accesses to the compromised Web sites. A number of detection approaches and tools against such attacks have been proposed so far. Especially, it is becoming easy to specify vulnerabilities of attacks, because researchers well analyze the trend of various attacks. Unfortunately, in the previous schemes, vulnerability information has not been used in the detection/prediction approaches of drive-by-download attacks. In this paper, we propose a prediction approach of “malware downloading” during drive-by-download attacks (approach-I), which uses vulnerability information. Our experimental results show our approach-I achieves the prediction rate (accuracy) of 92%, FNR of 15% and FPR of 1.0% using Naive Bayes. Furthermore, we propose an enhanced approach (approach-II) which embeds Opcode analysis (dynamic analysis) into our approach-I (static approach). We implement our approach-I and II, and compare the three approaches (approach-I, II and Opcode approaches) using the same datasets in our experiment. As a result, our approach-II has the prediction rate of 92%, and improves FNR to 11% using Random Forest, compared with our approach-I.

Abstract: Malware proliferation has become a serious threat to the Internet in recent years. Most of the current malware are subspecies of existing malware that have been automatically generated by illegal tools. To conduct an efficient analysis of malware, estimating their functions in advance is effective when we give priority to analyze. However, estimating malware functions has been difficult due to the increasing sophistication of malware. Although various approaches for malware detection and classification have been considered, the classification accuracy is still low. In this paper, we propose a new classification method which estimates malware’s functions from APIs observed by dynamic analysis on a host. We examining whether the proposed method can correctly classify unknown malware based on function by machine learning. The results show that the our new method can classify each malware’s function with an average accuracy of 83.4%.

Chih-Hung Hsieh; Yu-Siang Shen; Chao-Wen Li; Jain-Shing Wu, “iF2: An Interpretable Fuzzy Rule Filter for Web Log Post-Compromised Malicious Activity Monitoring,” in Information Security (AsiaJCIS), 2015 10th Asia Joint Conference on, vol., no., pp. 130–137, 24–26 May 2015. doi:10.1109/AsiaJCIS.2015.19
Abstract: To alleviate the loads of tracking web log file by human effort, machine learning methods are now commonly used to analyze log data and to identify the pattern of malicious activities. Traditional kernel based techniques, like the neural network and the support vector machine (SVM), typically can deliver higher prediction accuracy. However, the user of a kernel based techniques normally cannot get an overall picture about the distribution of the data set. On the other hand, logic based techniques, such as the decision tree and the rule-based algorithm, feature the advantage of presenting a good summary about the distinctive characteristics of different classes of data such that they are more suitable to generate interpretable feedbacks to domain experts. In this study, a real web-access log dataset from a certain organization was collected. An efficient interpretable fuzzy rule filter (iF2) was proposed as a filter to analyze the data and to detect suspicious internet addresses from the normal ones. The historical information of each internet address recorded in web log file is summarized as multiple statistics. And the design process of iF2 is elaborately modeled as a parameter optimization problem which simultaneously considers 1) maximizing prediction accuracy, 2) minimizing number of used rules, and 3) minimizing number of selected statistics. Experimental results show that the fuzzy rule filter constructed with the proposed approach is capable of delivering superior prediction accuracy in comparison with the conventional logic based classifiers and the expectation maximization based kernel algorithm. On the other hand, though it cannot match the prediction accuracy delivered by the SVM, however, when facing real web log file where the ratio of positive and negative cases is extremely unbalanced, the proposed iF2 of having optimization flexibility results in a better recall rate and enjoys one major advantage due to providing the user with an overall picture of the underlying distributions.

Abstract: Fail-stop signatures (FSS) provide the security for a signer against a computationally unbounded adversary by enabling the signer to provide a proof of forgery. Conventional FSS schemes are for a single-signer setting, but in the real world, there is a case where a countersignature of multiple signers (e.g. A signature between a bank, a user, and a consumer) is required. In this work, we propose a framework of FSS capturing a multi-signer setting and call the primitive fail-stop multisignatures (FSMS). We propose a generic construction of FSMS via the bundling homomorphisms proposed by Pfitzmann and then propose a provably secure instantiation of the FSMS scheme from the factoring assumption. Our proposed schemes can be also extended to fail-stop aggregate signatures (FSAS).

Abstract: Near Field Communication (NFC) technology is one of the most promising technologies in the field of mobile application services recently. The integration of NFC technology and smart mobile device (e.g., smart phones, tablet PC and etc.) stimulates the daily increasing popularity of NFC-based mobile applications which having proliferated in the mobile society. However, this proliferation of NFC-based mobile services in a mobile environment can cause another security threat in the field of mobile application services. Recently, mobile phishing and smishing are one of the most serious security issues in the mobile application services. And, the NFC tag-based mobile services (i.e. NFC tag based services) also have the same problem because an NFC tag have security vulnerabilities. Actually, NFC-enabled device can communicate with NFC tag using specified data format, be called NFC Data Exchange Format (NDEF). The NDEF message is composed one or more NDEF records such as text, URI, Smart post (text and URL) and so on. Therefore, if an attacker overwrite the NDEF message in a tag or replace a NFC tag with hacked tag, they might deliver a mobile malware to an NFC-enabled device. In this paper, a secure and lightweight authentication protocols for NFC tag based services is proposed which effectively achieves security with preventing spoofing, DoS, data modification and phishing attack. And, this authentication protocols are also requires less memory storage and computational power for low-cost NFC tags.

Abstract: Cloud computing has been developed rapidly in recent years, and offers novel concepts and innovations in computer use. The applications of cloud computing are that people can put their data on cloud and also can designate a proxy to help them to execute a number of tasks in certain situations. The proxy re-encryption which is a cryptographic primitive has been proposed to solve this problem. In the proxy re-encryption system, when a user (e.g., Alice) wants to send a cipher text that is encrypted by her public key and stored in the cloud to another user (e.g., Bob), she can designate a proxy to transform the cipher text into a different cipher text that can be decrypted by Bob’s private key. Recently, Fan et al. proposed an attribute-based encryption scheme with dynamic membership. However, we found that their scheme may be flawed. In this paper we will modify Fan et al.’s scheme to fix the flaw. Based on our modified scheme and the proxy re-encryption, we also propose an attribute-based proxy re-encryption under bilinear pairing. Furthermore, the proposed scheme has rich access policies and dynamic membership.

Abstract: Radio Frequency Identification (RFID) ownership transfer protocol aims at securely updating RFID tag’s internal state and key such that only the current owner of a tag is allowed to access the tag when it is transferred from one owner to the next.

Abstract: The most common method of tampering with a digital image is copy-move forgery, in which a part of an image is duplicated and used to substitute another part of the same image at a different location. In this paper, we present an efficient and robust method to detect such artifacts. First, the tampered image is segmented into overlapping fixed-size blocks, and the Gabor filter is applied to each block. Thus, the image of Gabor magnitude represents each block. Secondly, statistical features are extracted from the histogram of orientated Gabor magnitude (HOGM) of overlapping blocks, and reduced features are generated for similarity measurement. Finally, feature vectors are sorted lexicographically, and duplicated image blocks are identified by finding similarity block pairs after suitable post-processing. Experimental results demonstrate that the proposed method can detect multiple examples of copy-move forgery and locate precisely the duplicated regions, even when dealing with images distorted by translation, rotation, JPEG compression, blurring, and brightness adjustment.
