ePrint Report: A note on ``intelligent drone-assisted robust lightweight multi-factor authentication for military zone surveillance in the 6G era''

Zhengjun Cao, Lihua Liu

We show that the authentication scheme [Comput. Networks, 225 (2023), 109664] is flawed. (1) Some parameters are not specified. (2) Some computations are inconsistent. (3) It falsely require the control gateway to share its private key with the medical expert. (4) The scheme fails to keep user anonymity, not as claimed.
