摘要：
In this paper we proposed anew certificateless signature based on bilinear pairings. The proposed scheme is more efficient than those of previous schemes by pre-computing the pairing e(P, P) = g and publishing as the system parameters, it needs not to compute the pairing in the Sign stage, and only needs to compute three pairings in the Verify stage. In addition, the proposed scheme does not need the special MaptoPoint hash function and the confidential channel between KGC and users. The proposed scheme is unforgeable under the hardness assumption of the q-strong Diffie-Hellman problem and Computational Diffie-Hellman problem.
