We show that the key agreement scheme [J. Syst. Archit., 116: 102053, 2021] is flawed. It makes use of a symmetric key encryption to transfer data between the user and server. But the symmetric key is easily retrieved by an adversary, which results in the loss of data confidentiality, and makes it vulnerable to impersonation attack.
