A secure user anonymity-preserving biometric-based multi-server authenticated key agreement scheme using smart cards

作者：

Highlights：

• We analyze recently proposed Chuang and Chen’s scheme for multi-server environment.

• We show that their scheme is still vulnerable to different known attacks.

• We then propose an improved scheme with user anonymity and low computation overhead.

• Formal and informal security analysis/verification show that our scheme is secure.

• High security and low overhead make our scheme suitable for practical applications.
