一种基于生物特征的盲身份认证协议
首发时间:2014-06-11
摘要:伴随着互联网的迅速发展,互联网上的信息也相应的以指数化的速度增加,应用功能也愈发复杂,由此而来的信息安全问题也日益突出。信息安全一般包括几个方面:认证、数据库安全、计算机病毒防护、操作系统安全、数据加密以及访问控制等。而本文主要的关注点是认证方面的安全问题,而身份认证又是互联网认证安全的一个重要组成部分。由于生物特征是唯一的并且是于人直接关联的因素,具有不可抵赖的天然特性以及方便性,因此生物认证被认为可以提高身份认证的安全性。本文对目前存在的基于生物特征的远程身份认证方案进行了深入研究,并提出新的基于生物特征的盲身份认证方案,该方案可以有效的解决对于用户隐私,模板保护以及信任问题的担心。之所以称为盲认证,是因为它不会将除了用户ID以外的明文用户信息提供给认证服务器,该协议是基于非对称密码加密体系对生物数据进行加密。它同时拥有生物认证和公钥密码体系的优点。该认证协议可以在公共网络上运行,并且可以提供无法抵赖的身份识别机制。

A blind biometric authentication protocol
Abstract:Along with the development of the internet, the information on the Internet increases exponentially, the application functions become more and more complex, and the information security problem is increasingly outstanding. The information security generally includes several aspects: authentication, database security, computer virus protection, operating system security, data encryption, access control and so on. This article mainly focuses on authentication security and the identity authentication is an important part of Internet authentication security. Because the biological characteristics is unique and directly relate to individuals, also is non-repudiation and convenience, so the biological certification is considered to improve the security of authentication.This thesis studied and summarized the existing remote authentication scheme based on biological characteristics, and analyzed the safety defects in the scheme, then proposes a new blind identity authentication scheme based on biological characteristics. The scheme can effectively solve issues on user privacy, template protection and trust. The blind certification is so called because it would not give the authentication server any information by plaintext other than the user ID.The protocol would encrypt the biological data based on the asymmetric cryptographic system. It has the advantages of both biological authentication and public key cryptography system. The authentication protocol could run on the public network, and can provide can't denial identification system.
