针对无线传感器节点平均使用寿命短、带宽利用率低的现状，提出以减少中间节点数据传输次数、降低通信成本为目标的中间节点数据融合技术方案，该方案采用密文位数较小且安全性较高的椭圆曲线加密算法，再结合提出的可分离公钥同态加密算法，将多维数据压缩到一个密文，然后逐跳融合。通过实际构建无线传感器网络，搭建无线传感器网络安全数据融合实验平台验证，在传感器节点上实现了所需要的随机扰动算法和可分离同态加密算法，证明了方案的正确性、安全性以及高效性。

In view of the wireless sensor network’s nodes with limited average useful life,low utilization of broadband,this paper proposed a technical program of intermediate node data fusion to reduce the number of intermediate point data and com-munication cost,which adopted elliptic curve cryptography had small cipher digits and high security level.And combined the separable public key homomorphic encryption algorithm,it compressed the multidimensional data into a ciphertext,then jumped fusion.Through the actual construction of wireless sensor network,it built a wireless sensor network security experi-ment platform,and achieved all the required random disturbance algorithm and separable homomorphic encryption algorithm. The result proves that the proposed scheme’s correctness,security,high-efficiency.
