摘要
Abstract
Through the cryptanalysis of identity-based threshold proxy signature proposed by ZHANG Jianzhong. Which can not resist conspiracy attack, it is shown that any t proxy signers can conspire to gain enough information of other n-t proxy signers to generate proxy key and forge their signature. To avoid this attack, a new identity-based threshold proxy signature is proposed, which can resolve the security problem existing in existing scheme. The new scheme can resist the conspiracy attack and meets the safe requirements of threshold proxy signature scheme. Compared with existing scheme, the proposed scheme has obvious advantages in proxy key generation, proxy signature generation and total amount of calculation.关键词
