没有对运算的无证书盲签密方案

Certificateless Blind Signcryption Scheme without Pairing

无证书签密方案能够在一个逻辑步骤内同时实现数字签名和公钥加密两项功能,并且其计算量和通信成本都明显低于传统的先签名后加密的方式,同时解决了传统公钥密码体制存在的证书管理问题和基于身份密码体制中的密钥托管问题.结合无证书公钥密码体制和盲签密的思想,文章提出了一种高效的无证书盲签密方案,在计算量方面,没有对运算,效率非常高.

Certificateless signcryption can simultaneously fulfills both the functions of digital signature and public key encryption in a logically single step,and with a cost significantly lower than that required by the traditional signature followed by encryption,and also it is a new paradigm that overcomes the problem of certificate management in the traditional PKC and solves the inherent key escrow problem.In the paper,we propose a new high efficiency certificateless blind signcryption scheme by applying the concept of certificateless public key to blind signcryption,furthermore,it requires no pairing,so it is very efficiency.
