Certificateless Partially Blind Signature Scheme
Rong Wei-jian · Journal of Zhangzhou Normal University · 2008
Certificateless Public Key Cryptography as a new cryptographic paradigm was firstly introduced by Al-Riyami and Paterson in Asiacrypt 2003,which avoids the inherent key escrow problem of identity-based cryptography and does not require certificates to guarantee the authenticity of public keys as in the public key infrastructure.Partially blind signature is a variant of digital signatures,which allows the user to get a signature without giving the signer any information about the actual message and the resulting signature.Based on the Computational Diffie-Hellman Assumption,in this paper,we propose a certificateless partially blind signature scheme.
