摘　　要：针对无线传感器网络路由安全问题和节点能量有限的不足,提出一种基于分簇的安全路由协议CSRP。该协议是在LEACH基础上,以增强路由安全性同时兼顾网络的能量消耗为目标而设计的,通过引入适用于传感器网络的安全引导方案,一定程度上保证了数据的完整性、新鲜性以及认证性;同时引入双向评测机制,对恶意节点进行检测,有效地提高了网络的安全性能。仿真结果表明,在存在恶意节点的情况下,与LEACH和只能防止外部攻击的SecLEACH相比较,CSRP具有较好的抗捕获能力,而且增加的能量消耗很小。A secure cluster-based router protocol named CSRP is presented,it addresses the problems of inadequate consideration for security and limited energy in WSNs. CSRP, which is based on LEACH, takes saving of energy consumption and improving of routing security as its design targets. To some extent, key distribution scheme which is suitable for WSNs is added to CSRP to ensure the data integrity.freshness and authentication. Meanwhile, hi-directional evaluation mechanism is used to detect malicious nodes and enhance the network security. Simulation results show that the proposed protocol CSRP has better performance than LEACH and SecLEACH which only prevents outside attacks in terms of anti-capture ability while there exist malicious nodes. Furthermore,the energy consumption rises slowly.
