Efficient certificateless parallel multi-signature scheme
Caifen Wang · Journal of Computer Applications · 2010
A new efficient certificateless parallel multi-signature scheme was proposed based on the advantages of certificateless public key cryptosystem and the demands of digital multi-signature.The efficiency of the proposed scheme relied on that the pairing computation was not related to the number of signature users.The scheme decreased the pairing's number and was more efficient than known multi-signature schemes based on bilinear pairing technology.Furthermore,under the random oracle model,relying on the hardness of the Computational Diffie-Hellman(CDH) problem,the new scheme was proved to be secure against two attackers of certificateless parallel multi-signature.
