Securing the aggregated data of the wireless sensor networks (WSNs) is a vital issue to minimize energy consumption and face potential attacks. This paper presents a novel end to end encryption scheme defined as Aggregating Secure Data -Separate MAC (SDA-SM). The importance of the SDA-SM is twofold. First, it separates the secured aggregated data and the message authentication codes (MAC) into two different packets. Second, it transmits these packets in a random separate time-slot according to the scheduling of the TDMA. Moreover, the TDMA applied in the LEACH protocol is modified to adequate to the proposed SDA-SM scheme. The SDA-SM uses MACs to verify the integrity of the aggregated data and uses a sensor protected identifier to authenticate the source of data. The simulation results of the experiments assure the SDA-SM objectives can be achieved with less computation of the communication overheads than earlier techniques. Besides, SDA-SM will be able to accomplish the integrity and confidentiality of accurate aggregated data while saving the energy to prolong the network lifetime.

SDA-SM：使用跨无线传感器网络的独立MAC的高效安全数据聚合方案

确保无线传感器网络（WSN）的聚合数据的安全是至关重要的问题，它可以最大程度地减少能耗并面临潜在的攻击。本文提出了一种新的端到端加密方案，该方案定义为聚合安全数据-单独的MAC（SDA-SM）。SDA-SM的重要性是双重的。首先，它将安全的聚合数据和消息身份验证代码（MAC）分为两个不同的数据包。其次，它根据TDMA的调度在随机的单独时隙中发送这些数据包。此外，对LEACH协议中应用的TDMA进行了修改，以适合提出的SDA-SM方案。SDA-SM使用MAC来验证聚合数据的完整性，并使用传感器保护的标识符来认证数据源。实验的仿真结果确保与早期技术相比，只需较少的通信开销即可实现SDA-SM目标。此外，SDA-SM将能够实现准确聚合数据的完整性和机密性，同时节省能源以延长网络寿命。
