| 摘 要： | 文中分析了Khan等人提出的基于指纹和智能卡的远程双向身份鉴别方案,指出原方案不能抵抗伪造服务攻击、不能及时验证用户输入口令的正确性。提出了基于Rabin密码体制和nonce的改进方案,改进方案克服了原方案中存在的安全漏洞,保留了原方案中对指纹和智能卡的使用,且具有更高的安全性。

| Abstract: | The security of ＇a flexible biometrics remote user authentication scheme＇ proposed al. is studied, and this paper points out that this scheme is vulnerable to server masquerade attacks by Khan et and could not detect the error timely when the user enters wrong passwords. An improved programme based on Rabin and nonce is proposed, which could solve the security problem and maintain the use of fingerprint and smartcards in the original scheme. Moreover, the newly-developed scheme has an even higher security strength |
