The Conformation of Trusted Sensor Network

Due to the limited ability & energy for the computer, there are obvious weaknesses in sensor network than in traditional network on the aspect of system security. Moreover, the common methods of security can´t be implemented on sensor network. The idea of trusted computing can be used for sensor network security. Based on the trusted computer base and trusted chain, we propose a trusted sensor network framework, i.e. use the trusted server as a trusted computing base, modify the TinyPK authentication protocol, realize the extending of trusted chain, and therefore it can reduction of traffic can improve the expansibility and lifetime.
