摘要
椭圆曲线密码机制(ECC)是目前应用密码学的一个研究热点。介绍了ECC的基本算法,阐述了基于特征向量匹配的自动指纹识别过程。分析设计了三层架构的指纹身份认证系统,并采用基于椭圆曲线的Diffie-Hellman密钥交换协议生成用会话密钥,结合对称加密操作实现数据的安全传输,提高了系统的安全性和可靠性。
Elliptic Curve Cryptography（ECC） has become very popular in recent years because of its small key size and high security.Fingerprint recognition has applied to many fields.In this paper,the basic ECC algorithm was introduced,and Automatic Fingerprint Identification System（AFIS） was expounded.The design of a fingerprint-based identity verification system of 3-tier architecture was described.ECC was combined with private cryptography to generate the session key and encrypt fingerprints data,using an improved Diffie-Hellman protocol.
