“…We analyze the security of Wei et al's protocol and find a security defect in the IBS scheme [1] on which the protocol depends. Then, we analyze the impact of the security defect in the IBS on the protocol [1] and find that an RSU node can get the private keys of the OBU nodes with which it communicates through the common modulus attack. Moreover, we prove that the common modulus attack is feasible and effective in practice from the theory and experiments.…”

“…Moreover, we prove that the common modulus attack is feasible and effective in practice from the theory and experiments. Next, we propose an improved IBS scheme to replace Wei et al's [1] to resolve the security defect. We give the updated details of the protocol after applying the improved scheme and prove our improved IBS scheme is secure against chosen-message attack without random oracle.…”

Many sensitive data are generated by resource-limitation devices in the Vehicular ad hoc network (VANET). When these data are divulged, people 's life and property will be threatened. To solve these problems, Wei et al. proposed a lightweight privacy-preserving protocol based on RSA assumption for VANET and they claimed that their protocol was secure and low overhead. In this paper, first of all, we show that the basic signature scheme to be used in Wei et al.'s protocol is not secure, i.e., the user's private key will be revealed from the pairs of message-signatures, which causes the protocol to be insecure. We also show that our security analysis is feasible and effective in practice from the theory and experiments. Then we construct a new identity-based signature scheme based RSA assumption and prove it is existentially unforgeable under the chosen message attack without random oracle. Finally, we update the Wei et al.'s protocol and do some experiments to evaluate the efficiency of our scheme in the updated protocol.

“…V EHICULAR Ad Hoc Network (VANET), as a prominent form of Mobile Ad Hoc Network (MANET), plays an essential role in the future Intelligent Traffic System (ITS) by providing a wide range of applications to improve road safety and driving comfort. It is a distributed self-organizing network built up by high-speed vehicles [1], and is consisted of three parts: Trusted authorities (TA), Road Side Unit (RSU), and On Board Unit (OBU) [2]. TA can be regarded as an authority center that provides RSUs and OBUs with a variety of security services such as registration, identity authentication, and certificate management.…”

Context-Aware Quantification for VANET Security: A Markov Chain-Based Scheme

Recently, the quantification of VANET security has drawn significant attention due to the lack of standard computational metrics. The salient features of VANET, such as highly dynamic connections, sensitive information sharing, and unreliable fading channels, make the security quantification challenging. Accurate measurement for VANET security depends on the sufficient understanding of "context", or making sense of the states, environment, or situation. This paper proposes a context-aware security quantification scheme for VANET based on the Markov chain. Firstly, a Homogeneous Continuous-Time Markov Chain (HCTMC)-based security state model is designed for VANET. The value of each state of the HCTMC is determined with a value function that incorporates the security strength of transmitted data, dynamic and randomness of the vehicular channel, and transmission delay of the current situated environment of VANETs. Finally, the state transition matrix is derived based on the Homogeneous Discrete-Time Markov Chain (HDTMC) and Homogeneous Poisson Process (HPP). Simulation results show that the security quantification method enables the VANET's system to adopt context-aware defense strategies according to the situated environment.

An Efficient Cryptosystem for Video Surveillance in the Internet of Things Environment

Surveillance systems paradigm envisions the pervasive interconnection and cooperation of interactive devices over the Internet infrastructure. Nevertheless, dissemination and processing of surveillance video amid the Internet of Things (IoT) applications become a susceptible issue due to the large volume and the significant information of these data. Moreover, surveillance devices on IoT have very limited resources such as memory and storage. The actual security methods are not quite appropriate for surveillance IoT systems. Thus, a particular cryptosystem technique is required for surveillance data security. In this paper, we propose an efficient cryptosystem to secure IoT-based surveillance systems. The proposed cryptosystem framework contains three parts. First, a lightweight automatic summarization technique based on a fast histogram-clustering approach is used to extract the keyframes from the surveillance video. Then, we employ a discrete cosine transform (DCT) technique to compress the extracted data size. Finally, the proposed framework performs an efficient image encryption algorithm by employing a discrete fractional random transform (DFRT). The testing results and analysis confirm the features of the proposed cryptosystem on surveillance systems. The proposed framework is fast and ensures secure and efficient real-time processing by minimizing the transmission cost and storage.
