摘要
分析了无线传感器网络面临的安全威胁、需要解决的关键安全问题及安全协议设计原则.在此基础上给出了一个综合的安全解决方案和提升传感节点安全性能的系统设计方法,其可在增加少量系统消耗的基础上,提高无线传感器网络中通信的机密性、可靠性、完整性和时效性,同时减小传感节点被捕获后对整个系统安全性能造成的影响.
Security is a challenge in wireless sensor networks, The potential security threats, the key issues and design principles for achieving the security of wireless sensor network are analyzed. Integrated secure system architecture about sensor node to secure sensor network is presented. As a conclusion, the security requirements, such as confidentiality, integrity, authentication, freshness are provided while consuming little system resource and the impact on the whole network＇s security are minimized after some sensor nodes are captured and compromised as well.
