A Note on ``Secure Multifactor Authenticated Key Agreement Scheme for Industrial IoT''
Abstract
We remark that the key agreement scheme [IEEE Internet Things J., 8(5), 2021, 3801--3811] is flawed. (1) It is insecure against internal attack, because any unauthorized sensing device (not revoked) can retrieve the final session key. (2) It could be insecure against external attack.
