Abstract :
Aiming at the technology of threshold proxy signature is not yet perfect, there are still several problems about security and performance, the paper introduces bilinear pairings to signature scheme, suggests a threshold proxy signature scheme based on new probability signature. The scheme not only has all properties that a strongly-secure threshold proxy signature scheme should has, but also has short length of secret key and fast speed of encryption comparing with present schemes.
