Title:
Cryptanalysis and Improvement of Anonymous Authentication for Wireless Body Area Networks with Provable Security
Authors: Mahender Kumar
Abstract:Recently, He et al. proposed an anonymous authentication for wireless body area networks and prove that their scheme is secure in the random oracle model. In this paper, we cryptanalysis the He et al.’s scheme and design an attack model against their scheme, in which adversary replaces a user’s public key with a value of his choice and prove a key replacement attack besides client anonymity. Thus, their scheme is insecure and not suitable for implementing a secure WBAN system. Further, we point out a solution to improve their scheme.
