| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士在職專班 === 96 === Proxy signature schemes with anonymous proxy signers are called anonymous proxy signature schemes. Anonymous proxy signature schemes are used to protect proxy signers’ privacy. Among the proposed anonymous proxy signature schemes, Sum and Wei’s scheme is more practical than the other proposed scheme. However, their scheme does not satisfy strong unforgeability. Here, a new practical anonymous proxy signature scheme is first proposed with the help of concurrent signature schemes. In the new scheme, the anonymous names of proxy signers keep secret before use to protect proxy signers’ privacy.
