提出了一种新的密码原语——模糊生物特征签名加密方案，该方案在发送方和接收方的身份基于模糊生物特征字符串的情况下，可以在一个逻辑步骤中完成保密和认证。该方案具有容错特性，允许用户使用模糊生物特征字符串私钥解密字符串‘当且仅当band ’在一定距离内的消息。在给出方案模型和安全定义的基础上，提出了标准模型下的模糊生物特征加密方案，并对其安全性进行了分析，包括对自适应选择密文攻击的不可区分性和对自适应选择消息攻击的存在不可伪造性。
A new cryptographic primitive, called fuzzy biometric signcryption scheme which can perform confidentiality and authentication in a logic step while the sender and receiver identities are based on the fuzzy biometric string, is proposed. The proposed scheme possesses the error-tolerance property that allows a user with the private key for fuzzy biometric stringbto decrypt a message for stringb′ if and only ifbandb′ are within a distancet. After given the scheme model and security definitions, a fuzzy biometric signcryption scheme in the standard model is proposed and then then security are analyzed including indistinguishable against adaptively chosen ciphertext attack and existentially unforgeable against adaptively chosen message attack.
