摘　　要：生物识别加密技术通过密码学理论与生物特征相结合达到加强网络安全的目的。通过人类行为或者物理特征来识别个人身份是最可靠的识别方式。加密理论则进一步保障信息安全性,其对安全的保障程度取决于密匙强度,而这依存于秘钥的长度。传统加密算法中的秘钥是随机生成的,因此与用户无关联而难于记忆。生物识别加密技术通过用户的生物学数据将密匙与用户建立绑定免去记忆密匙的限制,本文基于相关加密理论,提出一种基于指纹识别的可撤销密匙生成算法。通过指纹数据库验证,本算法很好的解决了生物识别加密问题。Biometric cryptography aims to enhance network security by cryptography and biometric identification. The most reliable means to identify is to use specified behavior characters or physical features. Cryptography further secures the secret of information. The protection for information safety depends on the strength of the key which relies to the length of the key. The key is randomly generated in traditional methods, which is hard to memorize for the user. By introducing biometric identification, this problem might be solved. Based on relative cryptography theory, a Symmetric Cryptography based Revocable Key generation algorithm is proposed. Via real fingerprint data simulation, the proposed algorithm is proved to be effective.
