PBAG: A Privacy-Preserving Blockchain-based Authentication Protocol with Global-updated Commitment in IoV. (arXiv:2208.14616v1 [cs.CR])

Internet of Vehicles(IoV) is increasingly used as a medium to propagate
critical information via establishing connections between entities such as
vehicles and infrastructures. During message transmission, privacy-preserving
authentication is considered as the first line of defence against attackers and
malicious information. To achieve a more secure and stable communication
environment, ever-increasing numbers of blockchain-based authentication schemes
are proposed. At first glance, existing approaches provide robust architectures
and achieve transparent authentication. However, in these schemes, verifiers
must connect to the blockchain …
