Secure message dissemination is an important issue in vehicular ad-hoc networks, especially considering the vulnerability of vehicle-to-vehicle (V2V) message dissemination to malicious insider attacks. Traditional security mechanisms, largely based on message encryption and key management, are inadequate in such an environment where vehicles frequently exchange information with other “stranger” vehicles they never meet before. In this talk, I will present our recent work on secure message dissemination considering the topological impact of vehicular networks. By incorporating the underlying network topology information, we proposed an optimal decision algorithm that was able to maximize the chance of making a correct decision on the message content, assuming the prior knowledge of the percentage of malicious vehicles in the network. Furthermore, a heuristic decision algorithm was developed that removed the need to know the aforementioned percentage of malicious vehicles, which could be difficult to estimate. Simulations were conducted which demonstrated that the proposed algorithms could achieve much better performance than existing algorithms that did not consider or only partially consider the topological information. This work sheds light on the optimum algorithm design for secure message dissemination.
