【摘要】：无线传感网在许多大范围监测领域都有广泛的应用,在环境监测、军事侦察等领域都有规模化的应用。无线传感器节点通常被部署在环境恶劣的无人值守区域,容易节点受损或者节点受攻击,导致传感网的传输受到严重影响。根据无线传感器节点计算能力、存储空间有限的特点,我们设计了多跳长路径上多节点联合的数据认证机制,有效利用了数据认证机制保障了传输路径上的安全。深入研究了无线传感网中数据认证理论,设计实现了多跳长路径上多节点联合数据认证协议,进行虚假数据过滤,有效限制了攻击者利用妥协节点发动共谋攻击的威胁。并设计了路径上节点关系的维护算法,保证了数据认证机制的稳定性。最后对协议的安全性能进行了分析评价。针对多跳长路径上多节点联合数据认证协议的不足,对算法进行了优化,提出了多路径抗节点失效机制和动态步长多节点联合数据认证机制。目标是提升数据传输的可靠性,降低数据认证机制的通信开销,并对优化方案的安全性能进行了分析评价。围绕多跳长路径多节点联合数据认证机制的需求,对密钥分配方案进行了深入研究,提出了基于单向hash链的密钥分配方案。对认证中的MAC进行了研究,提出了适应数据认证机制需求的MAC码。通过仿真实验证明了本文中提出的方案的安全性能以及优化效果达到了预期目标。
[Abstract]:Wireless sensor network has been widely used in many fields in large-scale monitoring, environmental monitoring, military reconnaissance and other fields are applied. The scale of the wireless sensor nodes are usually deployed in unattended areas of poor environment, easy to damage or attack node node, sensor network transmission by computing power has been seriously affected. According to the characteristics of wireless sensor nodes, limited storage space, we design the authentication mechanism of data joint multi node multi hop path length, the effective use of data transmission security authentication mechanism on the path of data security. Wireless sensor network authentication theory deeply, the design and implementation of data combined with multi node multi hop authentication protocol long path, false data filtering, effectively limiting the attackers compromised node launched collusion attack threat. And the design of the relationship between the nodes on the path maintenance algorithm Method to ensure the stability of data authentication mechanism. Finally, the security performance of the protocol is analyzed. Aiming at the shortage of data combined with multi hop long path multi node authentication protocol, the algorithm is optimized, the multi paths of anti node failure mechanism and dynamic step multi node joint data authentication mechanism. The target is reliability to improve data transmission, reduce the communication overhead of data authentication, and the security performance of the optimization scheme is analyzed. The multi hop long path around the joint data multi node authentication mechanism needs to key distribution scheme is studied, put forward the key distribution scheme based on one-way hash chain authentication in MAC. The research, put forward to meet the demand of data authentication mechanism of the MAC code. The simulation results proved that the proposed scheme of safety performance and optimization effect reached the pre Target.
