摘要:Wireless sensor networks are a promising future of many commercial and military applications. However, these networks pose unique security challenges. While the deployment of sensor nodes in an unattended environment makes the networks vulnerable to a variety of potential attacks, the inher- ent power and memory limitations of sensor nodes makes conventional security solutions unfeasible. Though there has been some development in the field of sensor network security, the solutions pre- sented thus far address only some of security problems faced. The deployment of sensor networks in many sensitive applications requires an ample solution. This paper presents a computationally lightweight security framework to provide a comprehensive security solution against the known at- tacks in sensor networks. The proposed framework consists of four interacting components: a secure triple-key scheme (STKS), secure routing algorithms (SRAs), a secure localization technique (SLT) and a malicious node detection mechanism. Singly, each of these components can achieve certain level of security. However, when deployed as a framework, a high degree of security is achievable. The framework takes into consideration the communication and computation limitations of sensor networks. While there is always a tradeoff between security and performance, experimental results prove that the proposed framework can achieve high degree of security with negligible overheads
