摘要
在公钥密码体制中,加密是用来保证信息的机密性,数字签名可以确保消息的认证性、完整性和不可否认性,两者是独立存在,并分别被研究。而数字签密能在一个合理的逻辑步骤内同时实现加密和数字签名的功能,具有唯一性、高效性和安全性,可以简化需要同时达到保密和认证要求的密码协议的设计。本文针对签密方案进行简单的介绍,并列举了它的几个应用。
In the public key cryptography, encryption is used to ensure the confidentiality of information; while digital signature is used to ensure lhe message aulhentication, integrity and non-repudiation. They are two independent schemes anti studied respectively. Signcryption is a public-key primitive that simultaneously performs the functions of both digital signature and encryption. It has unique, efficiency and security properties, and it is better than any hybrid of digital signalure and encryption schemes under a particular model of security.This paper introduces the signcryption conception, implemenlalion and lists some applications.
