Abstract

In order to solve the problem that the power of the single KGC in certificateless short signature is too concentrated, this paper proposed a certificateless short signature scheme with double KGC, in which double KGC was restricted by each other. So it could effectively reduce the harm of the single KGC's main key leakage and malicious manipulation. Then, under the random oracle model, the difficult problem of k-CAA and Inv-CDH, it proved that the signature scheme was existentially unforgeable under adaptive chosen message attack. Finally, it compared the signature scheme with other certificateless schemes, and implemented the signature scheme in C language. The experimental results and analysis show that the scheme has lower computational cost, higher operating efficiency and security.
