A Note on ``A Time-Sensitive Token-Based Anonymous Authentication and Dynamic Group Key Agreement Scheme for Industry 5.0''
Abstract
We show that the Xu et al.'s authentication and key agreement scheme [IEEE Trans. Ind. Informatics, 18(10), 7118-7127, 2022] is flawed. (1) It confused some operations for bilinear maps and presented some inconsistent computations. (2) It failed to keep anonymity, not as claimed. The adversary can use any device's public key stored in the blockchain to test some verification equations so as to reveal the identity of a target device.
