摘　　要：生物特征身份以独特的优势成为信息安全领域当前所关注的热点。模糊提取器的提出,给从变化的生物特征中提取稳定的强密钥提供了可能。利用生物密钥将其应用到签密方案中,提出了"一种基于生物特征的签密方案"。避免了"在传统身份签密的过程中,签密者需要向权威机构证明自己身份"的繁琐过程,从而减少了证书管理的开销。最后对方案的有效性和安全性进行分析。The biometric identity becomes the focus of current field with the unique advantage of information security.The fuzzy extractors are proposed.Make to withdrew a stable strong airtight key to provide from the changed living creature characteristic possible.The text using biological keys applied to the signcryption scheme to proposed ＂a biometric identity-based signcryption scheme＂.The signer don＇t have to prove their identity for the authority,Which reduce the cost of the management of the certificate.Finally,This paper analyses the effectiveness and safety of the project.
