Certificate-based blind signatures from bilinear pairings
Zhenjie Huang, Qunshan Chen, Yanhua Hao · 2010
Certificate-based public key cryptography was introduced to remove the use of certificate to ensure the authentication of the user's public key in the traditional public key cryptography and to overcome the key escrow problem in the identity-based public key cryptography. Blind signature has the anonymity and plays a central role in applications such as electronic voting and electronic cash systems. Combining the concept of certificate-based cryptography with the concept of blind signature, in this paper, we propose an efficient certificate-based blind signature scheme assuming the hardness of Computational Diffie-Hellman Problem.
