Title:
Security flaws in a biometrics-based multi-server authentication with key agreement scheme

Authors: Debiao He

Abstract:

Recently, Yoon et al. proposed an efficient biometrics-based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem (ECC) for multi-server communication environments [E.-J. Yoon, K.-Y. Yoo(2011) Robust biometrics-based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem, Journal of Supercomputing, DOI: 10.1007/s11227-010-0512-1]. They claimed their scheme could withstand various attacks. In the letter, we will show Yoon et al.’s scheme is vulnerable to the privileged insider attack, the masquerade attack and the smart cart lost attack.
