碩士 === 國立臺灣海洋大學 === 資訊工程學系 === 96 === In this thesis, a delegation protocol subject to anonymous veto for an identity-based proxy multi-signature scheme is proposed. In this scheme, a number of original signers authorize an agent to sign document on behalf of them. The original signers in the authorization stage can be anonymous in case of a veto decision. The authorization process proceeds safely over public channels. This new protocol procides provides than the previous version in both computation and transmission more efficiency. As to the security aspect, the decisions of original signers achieve a high level of secrecy no matter what the decisions are. This delegation protocol also operates securely against the collusion attacks launched by the original signers.
