最近，Lee，Ryu和Yoo提出了一种基于指纹的远程用户认证方案，该方案使用智能卡和生物识别技术。他们的方案基于ElGamal的私钥密码系统和指纹验证的两层。该方案将生物特征认证技术引入到智能卡认证方案中，具有一定的创新性。在本文中，我们指出，他们的计划是脆弱的伪装攻击。我们提出了一个新的方案，以提高其安全性。此外，通过使用我们的方案，用户可以方便地选择和更改他们的密码。该方案适用于对安全性要求较高的应用。(C)2004 Elsevier B.V.保留所有权利。
Recently, Lee, Ryu and Yoo proposed a fingerprint-based remote user authentication scheme by using smart cards and biometrics. Their scheme is based on two tiers of ElGamal's private key cryptosystem and fingerprint verification. The scheme is novel by introducing biometrics verification technology into authentication scheme using smart cards. In this paper, we point out that their scheme is vulnerable to masquerade attack. We propose a new scheme to enhance their security. Furthermore, by using our scheme, users can conveniently choose and change their passwords. Our scheme is suitable for applications with high security requirement. (C) 2004 Elsevier B.V. All rights reserved.
