Title:
A Note on ``On the Design of Mutual Authentication and Key Agreement Protocol in Internet of Vehicles-Enabled Intelligent Transportation System’’
Authors: Zhengjun Cao, Lihua Liu
Abstract:We remark that the key agreement scheme [IEEE Trans. Veh. Technol. 2021, 70(2): 1736–1751] fails to keep anonymity and untraceability, because the user U_k needs to invoke the public key PK_{U_j} to verify the signature generated by the user U_j. Since the public key is compulsively linked to the true identity ID_{U_j} for authentication, any adversary can reveal the true identity by checking the signature.
