摘要
现有的基于身份具有消息恢复盲签名的文献数量少,安全性和效率也有待进一步提高。结合盲签名和消息恢复签名,利用双线性映射,构造了一种高效的基于身份具有消息恢复的盲签名方案。分析表明,该方案不仅能满足消息恢复盲签名所要求的所有性质,而且其效率也优于已有文献。
There are only a few ID-based blind signatures with message recovery which need to be improved in security and efficiency.In this paper,an efficient ID-based blind signature scheme with message recovery is proposed by using bilinear pairings and combining blind signature and signature with message recovery.lt is shown the proposed scheme can satisfy the fulfill properties of a blind signature with message recovery.Furthermore,its efficiency is also better than that of the existing ones.
