摘 要: 针对Z.Fangguo和R.Safavi-Naini给出的代理签名方案实现效率慢的问题,做了一些必要的改进,提出了效率更高,实现速度更快的基于双线性对的代理数字签名方案,并从存储空间和实现速度上系统证明了新方案的优越性。另外,运用这种新方案的思想,进一步提出了新的代理多重签名、多重代理签名和多重代理多重签名方案。 After analyzing the new bilinear parings proxy signature scheme proposed by Z.Fangguo and R.Safavi- Nai- ni, we find this scheme has low efficiency. To solve this problem, we makes some necessary amelioration and brings forward a new proxy signature scheme based on the bilinear parings. This new scheme has higher security and faster implementation speed. Besides, from memory space and implement speed aspect, we give the advantages of this new signature scheme. Finally, based on the main idea in this new scheme, we put forward new proxy multisignature scheme, new multi-proxy signature scheme and multi-proxy multi-signature scheme.
