源安全的传感器网络数据融合协议

Data fusion protocol with source security for sensor networks

针对源安全需求,构造了同时支持聚合签名、数据融合与批验证的特殊数字签名方案。该数字签名方案与同态加密技术相结合,设计了一个源安全的数据融合协议。安全性分析表明,该数字签名方案的安全性基于CDH问题的难解性,该协议能够同时保障采集数据end-to-end机密性与可认证性。

For the source security need,a digital signature scheme with aggregate signatures,data fusion and batch verification was proposed.Based on the proposed signature scheme and the homomorphic encryption technology,a data fusion protocol with secure sources was advanced.Security analyses show that the proposed signature scheme is secure based on the CDH assumption,and the proposed protocol can provide the collected data end-to-end confidentiality and authentication.
