AbstractThe processing ablity and response speed of the wireless communication terminals are limited, common signatures become the bottleneck to the development of the wireless networks. For that problem, based on the characteristics of the blind signature, the online/offline blind signature is given in this paper which incorporates with the optimal online/offline signature. Most computations are finished before the blind message is given, after that, only a few operations are needed. The performance analysis is also given in this paper, the new signature scheme can be applied to the security of wireless network, it protect the users’ privacy efficiently.
