摘要:

基于密码的用户远程认证系统已被广泛应用,近年来的研究发现,单一口令系统容易遭受字典分析、暴力破解等攻击,安全性不高。生物特征与密码相结合的认证方式逐渐加入远程认证系统中,以提高认证系统的安全水平。但现有认证系统通常工作在单一服务器环境中,扩展到多服务器环境中时会遇到生物特征模板和密码容易被单点突破、交叉破解的问题。为了克服以上问题,提出了一种基于生物特征和混沌映射的多服务器密钥认证方案,该方案基于智能卡、密码和生物特征,可明显提高多服务器身份认证系统的安全性及抗密码猜解的能力。

Abstract:

Password-based user remote authentication system has been widely used in recent years,the study found that a single password system is so vulnerable to dictionary analysis and brute force attack as well as other attacks that the security is not high.Biometric and password combination authentication method gradually added to the remote authentication system in order to improve the security level of authentication system.However,the existing authentication systems work in a single server environment,if extended to a multi-server environment,biometric templates and passwords will encounter single point breakthrough and cross-crack problem.In order to overcome the above problems,a multi-server key authentication scheme based on biometric and chaotic map was proposed.The scheme was based on smart cards,passwords and biometrics,which could significantly improve the security and the ability of anti-password guessing of multi-server authentication systems.

Key words: remote authentication, biometrics, multi-server
