Certificateless Blind Signcryption Scheme without Pairing
Xie Wen-jian · Journal of Guangxi University for Nationalities · 2011
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.
