Abstract

A new secure communication system is here presented for spontaneous and self-managed vehicular ad-hoc networks without any infrastructure on the road or vehicles. Our proposal prevents passive behavior of users who try to take advantage of the network without cooperating in its operation. In this paper we propose the use of encrypted exchange of data as a method to strengthen cooperation in VANETs. In particular, we describe a new pseudorandom generator based on a linear feedback shift register for encrypting sent information through a stream cipher, and analyze its output statistically.
