一种改进的多重代理签名方案

An Improved Scheme of Multi-proxy Signature

利用BLS短签名构建了一种改进的基于双线性映射的多重代理签名方案。该方案与其它方案相比,不仅更为高效,而且达到了强代理签名的安全性要求。测试表明,该文提出的方法是可行的、有效的,大大降低了攻击的影响。

This paper proposes an improved multi-proxy signaturc scheme. The improved scheme is constructed from.bilinear pairings using BLS short signatures. Due to the use of short signatures, the scheme is not only efficient, but also satisfies all thc security requirements of the strong proxy signature, It is proved that the design is available and feasible. It reduces the influence of attack.
