Abstract: Combining with Wei and Yuen’s short signature,a new multi-level proxy signature scheme based on q-SDH assumption is proposed in this paper.It has the properties of non-repudiation,unforgeability,undeniability and many other properties multi-level proxy signature scheme needs to possess.Therefore,the proxy signature right can come true step by step under agreement.

Key words: proxy signature, multi-level proxy signature, q-SDH assumption, bilinear paring

摘要: 以Boneh和Boyen提出的强Diffie-Hellman(q-SDH)假设为基础,结合Wei和Yuen的短签名方案,提出了一种新的多级代理签名方案。该方案具有不可否认性、不可伪造性、不可抵赖性以及多级代理需具备的其它性质,实现了签名权在允许范围内的逐级代理。
