Analysis of One Certificateless Authentication and Key Agreement Scheme for Wireless Body Area Network
Abstract
We show that the certificateless authentication scheme [Mob. Networks Appl. 2022, 27, 346-356] 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. The adversary can retrieve the user's identity from one captured string via the open channel.
