Abstract

In 2008, Barbosa and Farshim introduced the notion of certificateless signcryption (CLSC) and proposed the first CLSC scheme [2], but which requires six pairing operations in the signcrypt and unsigncrypt phases. In this paper, aimed at designing an efficient CLSC scheme, we propose a new efficient CLSC scheme from bilinear maps, which requires only two pairing operations in the signcrypt and unsigncrypt phases and is more efficient than all the schemes available.
双线性映射的有效且可证明安全的无证书签名加密
2008年,Barbosa和Farshim引入了无证书签名加密(certificeless signcryption, CLSC)的概念,并提出了第一个CLSC方案[2],但该方案需要在signcrypt和unsigncrypt阶段进行6次配对操作。为了设计一种高效的CLSC方案,我们提出了一种新的基于双线性映射的CLSC方案,该方案只需要在signcrypt和unsigncrypt阶段进行两次配对操作,并且比现有的所有方案都要高效。
