摘要: 基于身份的公钥密码系统是基于证书的公钥系统的一个很好的替代,大大减少了证书管理的开销。利用生物特征身份信息构造公钥,提出了一个基于生物特征身份的签名方案并对其安全性作了分析。对于在线支付系统,新方案比以前提出的数字签名方案更具优势,会进一步提高系统的安全性和可靠性。

Abstract: Identity-based (ID-based) public key cryptosystem can be a good alternative for certificate-based public key system, which decreases the cost of certificates management greatly. A biometric identity-based signature scheme is proposed, which uses biometric information to construct the public key, and its security is also analyzed. For on-line payment system, the new scheme has higher security and reliability than the digital signature schemes previously proposed.
