摘要
在无线传感器网络中,数据融合是实现有效传输和节省能源的一个重要途径,许多应用都需要可靠并且可信的数据来进行融合。针对上述要求,提出了一个新的安全数据融合算法来保证融合数据的机密性和完整性。算法使用端到端加密和逐跳加密相结合的方式进行数据传输,通过认证过程进行恶意节点及伪造数据的检测。仿真表明,提出的算法能够有效地检测出恶意节点,并保证融合结果的准确性。
Data aggregation is an important solution for achieving effective transmission and better power conservation in wireless sensor networks. Many applications require reliable and trustful data aggregation. Aimed at the demand, a new secure data aggregation algorithm is proposed to ensure the confi- dentiality and integrity of aggregated data. The algorithm uses the blend of end-to-end and hop-by-hop encryption for data transmission, and attestation algorithm to detect the malicious node and forged data. Simulation results show that tile proposed algorithm can effectively detect malicious nodes and en- sure the accuracy of the aggregation.
