Abstract

In the fields of intelligent transportation (InTrans) and vehicle ad hoc networks (VEAHT), data exchange between vehicle and vehicle or between vehicle and RSU (Road Side Unit) or between RSU and RSU or so on can cause many security problems such as sending a fake data or pretending to be a vehicle node or others. At the same time, in InTrans and VEAHT, data exchange is very frequent and also is very large. Batch authentication protocol or scheme based on pseudonym identity can improve the efficiency of message signature verification. What’s more, it can protect the real identity of the vehicle node by using a pseudonym but the real identity can be traced when needed. In this paper, the security of two batch authentication schemes proposed recently is analyzed. This paper shows that the two schemes exist some security drawbacks and do not satisfy the security properties: unforgeability and traceability. In other words, a malicious vehicle (acts as an attacker) can forge a signature on a message without knowing the private key of the vehicle node and anyone cannot trace the real identity of the attacker. Finally, this paper also gives a simple improvement on the existing security drawbacks.
