Cryptanalysis and improvement of a biometrics-based multi-server authentication with key agreement scheme
Hakhyun Kim, Woongryul Jeon, Yunho Lee, and Dongho Won
Abstract
In 2010, Yoon et al. proposed a robust biometrics- based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem. In this letter, however, we show that Yoon et al.’s scheme is vulnerable to off-line password guessing attack and propose an improved scheme to prevent the attack.
