摘要

For the traditional threshold signature mechanism does not considers whether the nodes which generate part signature are trusted and the traditional signature strategy doesn’t do well in resisting internal attacks and external attacks and collusion attacks, so this paper presents a new threshold signature based on Trusted Platform Module (TPM), based on TPM the signature node first should finish the trust proof between it an other members who take part in the signature. Using a no-trusted center and the threshold of the signature policy, this strategy can track active attacks of the key management center and can prevent framing the key management center, this strategy takes into account the limited computing power TPM and has parameters of simple, beneficial full using of the limited computing power TPM.
