Title:
A note on ``ISG-SLAS: secure and lightweight authentication and key agreement scheme for industrial smart grid using fuzzy extractor’’
Authors: Zhengjun Cao, Lihua Liu
Abstract:We show that the key agreement scheme [J. Syst. Archit., 131:102698, 2022] fails to keep user anonymity and service provider anonymity, not as claimed. The scheme simply thinks that user anonymity is equivalent to protecting the target user’s identity against exposure, while its long-term pseudo-identity can be exposed. We want to clarify that the true anonymity means that an adversary cannot attribute different sessions to different target users, even if the true identifier cannot be retrieved from the exposed pseudo-identifier.
