Abstract :
Transport safety applications aim at avoiding vehicular accidents by using secure broadcast vehicle-to-vehicle (V2V) communications. However, any security mechanism used for authenticating broadcast V2V messages comes with overhead in terms of computation and communications. The IEEE1609.2 standard for vehicular ad hoc networks is based on the ECDSA algorithm for supporting the authentication mechanism. This paper provides an assessment of the processing overhead of ECDSA. We describe the impact of this mechanism on VANET performance. Then we focus on the impact of authentication processing on the braking distance.
