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.
