Research on the Resistance to Adaptive Attacks in the Internet of Vehicles Based on SM2 Ring Signature

Blockchain technology can protect the privacy and security of members of the Internet of Vehicles, but it is vulnerable to adaptive attacks. This article proposes an anonymous election algorithm using the unconditional anonymity of SM2 ring signatures to secretly elect the master node in each round of consensus, effectively resisting adaptive attacks; The analysis results show that the work in this paper ensures the privacy security of the members of the vehicle networking, and can ensure the operational security of the vehicle networking in the face of malicious node attacks.
