A Note on ``a two-factor security authentication scheme for wireless sensor networks in IoT environments''

Abstract

We show that the scheme [Neurocomputing, 2022 (500), 741-749] fails to keep anonymity, not as claimed. The scheme neglects the basic requirement for bit-wise XOR, and tries to encrypt data by the operator. The negligence results in some trivial equalities. An adversary can retrieve the user's identity from one captured string via the open channel.
