Robust Biometrics-Based Authentication Scheme for Multiserver Environment 论文

摘要

The authentication scheme is an important cryptographic mechanism, through which two communication parties could authenticate each other in the open network environment. To satisfy the requirement of practical applications, many authentication schemes using passwords and smart cards have been proposed. However, passwords might be divulged or forgotten, and smart cards might be shared, lost, or stolen. In contrast, biometric methods, such as fingerprints or iris scans, have no such drawbacks. Therefore, biometrics-based authentication schemes gain wide attention. In this paper, we propose a biometrics-based authentication scheme for multiserver environment using elliptic curve cryptography. To the best of our knowledge, the proposed scheme is the first truly three-factor authenticated scheme for multiserver environment. We also demonstrate the completeness of the proposed scheme using the Burrows-Abadi-Needham logic.
