| 英文摘要 | In 2004, hwang and chen demonstrated new multi-proxy multi-signature schemes that allow a group of authorized proxy signers to sign messages on behalf of a group of original signers. later, lyuu and wit pointed out hwang et al.'s schemes were not secure and then proposed a modified scheme. they claimed that their modified schemes were secure. but in this paper we show a new attack on the lyuu-wu et al.'s schemes. moreover, the original hwang-chen's schemes are also vulnerable to this insider attack. furthermore, we point out some improvements for the lyuu-wu scheme and hwang-chen schemes according to wang et al.'s methods [wang gl, han xx, zhu b. on the security of two threshold signature schemes with traceable signers. in: applied cryptography and network security (acns 2003). lect notes comput sci (lncs), vol. 2846, springer-verlag; 2003. p. 111-222]. these improvements can resist our insider attack.
