摘要
在已有的基于身份部分盲签名的基础上,提出了一种改进的基于身份的部分盲签名方案。该方案可用来提高电子现金、电子投票等系统的效率。分析表明提出的改进方案不仅能满足部分盲签名的各种性质,而且其性能也优于已有方案。
An improved ID-based partially blind signature is proposed on the basis of the existing ones.The proposed scheme can be used to improve efficiency in electronic cash and electronic voting systems.h is showed that the proposed scheme can satisfy all the properties of an ID-based partially blind signature.Furthermore,its efficiency is also better than that of the existing ones.
