摘要
无线传感器网络数据融合技术能减少冗余信息的传输量,降低能耗,延长网络生命期。由于传感器节点通常部署在开放甚至敌对的环境中,数据融合的安全性尤为重要。端到端加密与认证的数据融合方案相比逐跳方案具有更强的抗节点捕获能力。为此,在CMT方案的基础上,提出一种密钥生成算法、一种高效的同态消息认证码算法以及一种优化的节点ID传输方案。分析与模拟结果表明,在保证安全性的前提下,该方案能有效降低计算和传输的开销。
Data aggregation technology in wireless sensor networks can reduce the transmission throughput of redundant information, lower energy consumption, and prolong network lifetime. Due to open or hostile environment in which the nodes are deployed, the security of data aggregation is of great important. Data aggregation schemes with end-to-end encryption and authentication provide better protection against node capture attacks than hop-by-hop schemes. Therefore, based on the CMT scheme, this paper proposes a key generation algorithm, an efficient homomorphic MAC algorithm and an optimised node ID transmission scheme. Analysis and simulation results show an effective reduction in the cost of computation and transmission, while the security is guaranteed.
