| Summary: | 碩士 === 國立交通大學 === 資訊科學系 === 91 === A (t,l) threshold proxy signature is a signature scheme that is designed to delegate the original signer signing capability to a designated group of l proxy signers. Only any t or more proxy signers of the designated group can generate the proxy signature behalf of the original signer.
In this thesis, we propose the first (t,l) threshold proxy signature scheme based on GQ signature. The proposed scheme satisfies all requirements of a proxy signature and a threshold signature under adaptive adversary.
