A privacy-aware reputation-based announcement scheme for VANETs

An announcement scheme is a system that facilitates vehicles to broadcast road-related information in vehicular ad hoc networks (VANETs) in order to improve road safety and efficiency. Here we propose a new cryptographic primitive for public updating of reputation score based on the Boneh-Boyen-Shacham short group signature scheme. This allows private reputation score retrieval without a secure channel. Using this we devise a privacy-aware announcement scheme using reputation systems which is reliable, auditable and robust.

“…In another dimension, Li et al [23] proposed to a reputation-based announcement system in which a central authority maintain and keep track of the reputation of each node so that vehicles could choose to trust messages coming from nodes with a high reputation. Subsequently, Li et al [29] and Chen et al [10] further enhances this framework by providing privacy protection to the nodes.…”

Vehicular Ad Hoc Network (VANET) allows vehicles to exchange information about road and traffic conditions through wireless communications. Nevertheless, providing reliable and authenticated information without violating the user's privacy seems contradictory. In this paper, we propose an Anonymous Announcement System especially designed for Electric Vehicle (EV) in VANETs to achieve the aforementioned contradictory goals. We demonstrated the feasibility of the protocol with a prototype implementation on a suitable device and a network simulation with our protocol added on top of a normal VANET.

“…The secure routing technologies of mobile ad hoc network cannot be fully applied to the VANET, so how to efficiently design security and trust mechanisms in routing process is needed in VANET. At present, the literature [3][4][5] proposed some VANET reputation models through the assessment of the reliability of messages. But they do not consider the problem of trust management of secure routing.…”

The particularities of the high dynamic, temporary meeting make the trust and cooperation between vehicles more difficult. To solve this problem, by using trust management model of Bayesian and in the light of the three kinds of opportunistic routing forwarding model, this paper puts forward a trusted routing protocol in VANET Based on GeoDTN+Nav routing protocol. The proposed protocol not only improves the security of routing, but also has the lower time complexity. Experimental results and analysis show that the proposed protocol has achieved good performance in the removal ratio of malicious nodes, correct reception ratio of packet and the message payload.
