A note on ``a novel authentication and key agreement scheme for Internet of Vehicles''

Zhengjun Cao
Abstract

We show that the Yang et al.'s key agreement scheme [Future Gener. Comput. Syst., 145, 415-428 (2023)] is flawed. (1) There are some inconsistent computations, which should be corrected. (2) The planned route of a target vehicle is almost exposed. The scheme neglects the basic requirement for bit-wise XOR, and tries to encrypt the route by the operator. The negligence results in some trivial equalities. (3) The scheme is insecure against impersonation attack launched by the next roadside unit.
