Security in vehicular ad hoc networks

Abstract

Vehicular networks are likely to become the most relevant form of mobile ad hoc networks. In this paper, we address the security of these networks. We provide a detailed threat analysis and devise an appropriate security architecture. We also describe some major design decisions still to be made, which in some cases have more than mere technical implications. We provide a set of security protocols, we show that they protect privacy and we analyze their robustness, and we carry out a quantitative assessment of the proposed solution.

A Recent Survey on Authentication Schemes with Privacy Preservation in VANETs

“…The time to compute the Hash and the signature is TH, Ts is 0.09ms, 0.39ms. M.Rekik et al [21] proposed an enhancement to before work [22] which gives an answer for authentication problem as, dual authentication with key management. The enhancement achieved in this work is introducing extra authentication segment and a re-authentication phase, with the aid of retaining the amount of data required to compute for the authentication in a computationally environment friendly way.…”
