“…Similar to our work, a simple method is to use pseudonyms, which however may cause many issues. In [6], Lu et al consider a scenario when the pseudonyms are changed at improper location or time, for example, on the road. In this way, the location and velocity information embedded in the safety messages could still provide a clue for an adversary to link the pseudonyms, which leads to privacy leakage.…”

“…The problem can be settled by incorporating trust which allows each vehicle to detect malicious relay vehicles who drop messages deliberately, and to give incentives to encourage reliable vehicles [5]. Meanwhile, location privacy has always been a concern in VANET since the locations of the vehicles are closely related to the drivers of those vehicles [6]. To achieve location privacy, a very popular approach in VANET is that vehicles periodically change their pseudonyms when broadcasting messages [1,7,8], since the pseudonyms make the location information in a period unlinkable to a specific vehicle.…”

As one of the essential components of Intelligent Transport Systems (ITS), Vehicular Ad Hoc Network (VANET) plays a significant role in enabling various onroad applications, most of which primarily rely on two-hop Vehicle-to-Infrastructure communications. To make such communications reliable and secure, it is significant to ensure that only the trustworthy vehicles are selected as relays. To tackle this challenge, this paper proposes a robust trust-based relay selection scheme, called PTRS, which, based on Dirichlet distribution, systematically integrates a set of unique features of VANET, e.g., hybrid architecture, high dynamics, into the traditional reputation system, with an objective to effectively differentiate the trust levels of the vehicles, meanwhile, preserving robustness. Besides, the location privacy of vehicles are preserved in our proposed scheme by using the technique of pseudonyms and trust levels instead of explicit reputation scores. Detailed security analysis is conducted, which shows that the proposed PTRS scheme is secure and robust against several sophisticated attacks in VANETs. In addition, a set of extensive simulations are carried out, demonstrating its effectiveness and accuracy.

The digitization of patient health information has brought many benefits and challenges for both the patients and physicians. However, security and privacy preservation have remained important challenges for remote health monitoring systems. Since a patient's health information is sensitive and the communication channel (i.e. the Internet) is insecure, it is important to protect them against unauthorized entities. Otherwise, failure to do so will not only lead to compromise of a patient's privacy, but will also put his/her life at risk. How to provide for confidentiality, patient anonymity and un-traceability, access control to a patient's health information and even key exchange between a patient and her physician are critical issues that need to be addressed if a wider adoption of remote health monitoring systems is to be realized. This paper proposes an authenticated privacy preserving pairing-based scheme for remote health monitoring systems. The scheme is based on the concepts of bilinear paring, identity-based cryptography and non-interactive identity-based key agreement protocol. The scheme also incorporates an efficient batch signature verification scheme to reduce computation cost during multiple simultaneous signature verifications.

To increase the road safety and secure communication among the vehicles in the network environment, Dedicated Short Range Communication (DSRC) is followed. Nowadays, research over DSRC is dramatically increased for enhancing the road safety applications. The main task of DSRC is to protect the vehicles by communicating the warning message regarding the vehicle changing conditions, traffic occurrence and dangers over the road in the network. So, it is necessary to maintain the accurate communication timely with high reliability by implementing the appropriate protocol. In the literature there are several methods which provided specifications defined in the physical layer and the Medium Access Control (MAC) layer. In those methods, current IEEE 802.11p MAC is not able to provide predictable Quality of Service (QoS) for high-priority safety services. Motivated by the fact that the existing work provided three levels of safety-related broadcast services, but did not focus on current traffic load conditions, in this study, we plan to present Traffic Controlled DSRC (TC-DSRC) model to analyze and categorize the traffic patterns in the vehicular communication for safety related application. A new algorithm is presented to evaluate the process of traffic controlled DSRC model for secure communication in VANET. The dedicated short range communication broadcast of messages is sent to all the vehicles at a specific instance for defined radius on the traffic zone. Multiple traffic load conditions are categorically stated to handle the vehicular safety with quick response time. Integrating these two performance metrics (i.e., quick response time and security), by using the proposed algorithm, the traffic patterns are categorized for communication between vehicles to provide the safety measure. In addition, our proposed scheme with the categorization using traffic patterns improves the network performance by deriving a specific pattern. Compared with the recent standard of 802.11p wireless vehicular networks the scheme proposed in this study is more robust and operate under vehicle-to-vehicle mode in order to address the secure communication between the vehicles. The effectiveness of secure communication in vehicular ad hoc network with varied vehicular speed and changing network topology is evaluated numerically using realistic simulation data obtained from traffic engineering systems.
