摘 要: 研究了基于生物特征的密钥提取,利用模糊提取器将不可精确再生和非均匀分布的生物特征数据生成为可应用于经典密码体系的密钥,密钥的产生和用户的认证紧密结合,使认证和密钥产生这两个密码操作统一在一个密钥原语中实现.并将生物特征数据生成的密钥应用于短签名等经典的数字签名方案,从而达到更高的安全性和实用性. In this paper, we present a biometric identity based signature scheme, studied the key extraction based on biological characteristics, the use of fuzzy extraction device will not accurate regeneration and non-uniform distribution biometrie data born become can be applied to the classic secret system keys, key and the formation of the user's authentication closely, make authentication and key produce the two codes in a key operation unification in the s^uree [~nguage realization, Biometric data and the key generated from applied in short signature and other classic digital signature scheme, so as to achieve a higher safety and p^acticality.
