无线传感器网络安全系统的研究与设计

无线传感器网络（WSN）是一种新型无线网络，它有许多优点；但是也存在一些问题，这些问题让攻击者能够更轻易的分析网络安全漏洞，进行攻击并摧毁整个网络.本文设计了一个安全的无线传感器网络模型.它能够抵御大多数已知的网络攻击，且不会明显降低传感器节点（SN）的能量功率.我们建议对网络组织进行聚簇以降低能耗，并基于对信任级别的计算以及可信节点之间信任关系的建立来保护网络，基于集中式的方法对信任管理系统进行运作.实验结果表明：本文设计的无线传感器网络模型解决了高效节能的设计任务，信任管理系统在防御攻击上的结果令人满意.

Research and Design of Wireless Sensor Network Security System

Wireless sensor network (WSN) is a new type of wireless network. It has many advantages, but there are also some problems, which allow adversary much easier to analyze network vulnerabilities, to conduct an attack and destroy a whole network. This paper proposes a model of secure wireless sensor network, which is able to defend against most of known network attacks and doesn''t significantly reduce the energy power of sensor nodes (SN). We propose clustering as a way of network organization, which reduces energy consumption. Network protection is based on the calculation of the trust level and builds trusted relationships between trusted nodes. Operation of trust management system is based on a centralized method. The experimental results show that the wireless sensor network model designed in this paper solves the task of development of energy efficient; TMS shows satisfied results in preventing the attacks.
