中文摘要：

针对节点的能量损耗、通信带宽、存储空间等有严格限制的无线传感器网络环境,基于双线性配对,本文提出门限签名方案。在假设计算Diffie-Hellman问题困难的前提下,利用规约到矛盾的方法给出在随机预言机模型下的严格安全性证明。此外所提的方案具备群合作条件下应有的顽健性,可以进行多签,满足分布式并行计算等特点,非常适应于无线传感器网络。

英文摘要：

Compared with traditional network,the wireless sensor nodes are limited in the storage,mobility,computation,energy,and so on.A threshold ring signature scheme suitable for wireless sensor networks based on bilinear pairings was proposed.Assuming the abstrusity of computational Diffie-Hellman problem,the secure proof was shown in the model of random oracles using the reduction to the contravention.Proposed scheme also had other characteristics,such as robust-ness,multi-signature and parallel computation.
