摘　　要：安全数据融合的目标是在融合数据的同时,实现传感器节点感知数据end-to-end机密性与可认证性。End-to-end机密性一般由秘密同态加密技术来保障。针对end-to-end可认证性与数据融合的矛盾,在同态认证技术不适用于多源多消息的背景下,为了实现end-to-end可认证性,采用对称加密技术构造了一个安全的数据融合认证方案。采用该数据融合认证方案与秘密同态加密方案,构造了安全的数据融合协议。安全性分析表明,该安全数据融合协议能在融合数据的同时保障感知数据end-to-end机密性与可认证性。Secure data aggregation aims at realizing the end-to-end confidentiality and authentication of the data,which is collected and aggregated by sensor.End-to-end confidentiality is usually guaranteed by the privacy homomorphic encryption.However,the homomorphic authentic schemes are not multi-source and multi-message.For the contradictions between the end-to-end authentication and the data aggregation,a secure data aggregate authentic scheme was proposed.A secure data aggregate protocol was constructed with the proposed authentic scheme and a homomorphism encryption scheme.Security analysis result shows that the proposed data aggregate protocol can obtain the end-to-end confidentiality and authentication of the collected data.
