On the Anonymity in "A Practical Lightweight Anonymous Authentication and Key Establishment Scheme for Resource-Asymmetric Smart Environments"
Abstract
We show that the anonymous authentication and key establishment scheme [IEEE TDSC, 20(4), 3535-3545, 2023] fails to keep user anonymity, not as claimed. We also suggest a method to fix it.
