摘要: 提出一种基于身份的广义签密算法,该算法以一个密码模块实现签密、加密和签名3种功能,减少密码组件,可满足于更广泛的应用需求。给出详细定义,验证算法的正确性,并对其性能进行分析。分析结果表明:算法同时满足机密性和可认证性,与已有的L-K算法相比,在不考虑预计算的情况下,计算量具有一定优势。

Abstract: An identity-based generalized signcryption algorithm, which can fulfill signcryption, encryption and signature by one cryptographic module, is proposed to serve the broader applications. It gives an elaborate define and made an analysis of its validity and performance. The analysis shows that the algorithm achieves authenticity and confidentiality synchronously, and it has evident advantage compared to L-K scheme without considering pre-computation.
