在无线传感器数据融合技术中，为了实现端到端数据传输完整性验证，在同态认证技术不适用于多源多消息的背景下，利用同态哈希函数和聚合签名思想，提出一个基于身份的数据完整性验证技术。技术基于公钥密码体制，进一步提高了系统的安全性；基站可以验证来自不同传感器节点拥有不同私钥的消息，也可以根据收到的融合消息计算出每个传感器节点的权重。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数据完整性与可认证性。数值结果说明该算法在传感器节点的计算效率优于已有的方案。

In order to realise the verification of end-to-end data transmission integrity in data aggregation of wireless sensor networks , we propose an ID-based data integrity verification scheme using homomorphic hash function and aggregation signature idea under the background of homomorphic authentication technology does not fit the multi-source multi-message.The scheme is based on public key cryptosystem , this further improves the security of the system;the base station can verify the message of the nodes from different sensors having different private key, and can also compute the weight of each sensor node according to the aggregation message received .Security analysis demonstrates that the security data aggregation protocol can guarantee the integrity and authentication property of data while aggregating data .Numerical result illustrates that our scheme is better than the existing scheme in sensor nodes computation efficiency .
