(English Abstract)
Security in communication is still an important issue because information transmitted via VANET provides safety-related services to drivers. In this context, there have been many studies related to the sending and receiving messages securely in VANET. In many studies, the RSU was assumed as a trust or semi-trust device and RSU played an important role in message authentication. However, a large number of RSUs cannot be considered trustworthy because the security of the RSU cannot be secured. Therefore, this paper proposes a message authentication scheme that is not dependent on the RSU. For this, a group key based on CRT (Chinese Remainder Theorem) is used. In the proposed scheme, the CRT-based key server calculates and distributes a 'private key' and a 'group key seed' to each vehicle. Then, each vehicle extracts the group key from the group key seed and uses it to authenticate the message. The proposed scheme eliminates the RSU dependence in a message verification. And it is also possible to easily withdraw a vehicle from a group.
