Security is a fundamental issue for promising applications in a VANET. Designing a secure protocol for a VANET that accommodates efficiency privacy and traceability is difficult because of the contradictions between these qualities. In this paper we present a secure yet efficient protocol for a VANET that satisfies these security requirements. Although much research has attempted to address similar issues we contend that our proposed protocol outperforms other proposals that have been advanced. This claim is based on observations that show that the proposed protocol has such strengths as light computational load efficient storage management and dependability. 1. Introduction We are evolving into a society with nearly constant access to the Internet and its vast wealth of information. The key driver of this evolution has been the desire for data sharing through opportunistic contacts in collaborative networks. In this opportunistic environment the always-on assumption is relaxed by allowing data transport even in the absence of a contemporaneous end-to-end path between the source and the destination. This paradigm is a radical departure from the .
