一种基于TD-ERCS生物特征密钥提取的鉴别方案

An Authentication Scheme based on TD-ERCS extracting Biometrics Key

为解决传统密码技术需要外部的真随机数或伪随机数产生器产生密码的问题,将切延迟椭圆反射腔混沌系统(TD-ERCS)应用到生物特征密钥提取技术中,即由生物特征直接产生系统所需密钥,降低了系统的成本和复杂性。提出了一种基于该密钥提取技术的全新鉴别方案,能有效解决对合法用户进行身份认证时密码和密钥遗忘、被盗、被破解的现象。基于该技术的鉴别方案能应用于我们生活中的各个领域。

Traditional cryptographic techniques needed external ture-random number or pseudo-random number generator to generate passwords,inorder to solve the problem,tangent delays elliptical reflector cavity chaotic system（TD-ERCS） was applied to the Biometrics key extraction technology.That＇s to say,the key of the system can be generated directly from biological features.It＇s a very good solution to reduce the system cost and complexity.Meanwhile,we proposed an new authentication scheme based on the biometrics key extraction technology.It can eradicate the situations of the password forgotten,stolen,cracked for the legitimate user when they are in the authentication.The technology-based authentication？scheme can be applied to all areas of our lives.
