Abstract: Wireless sensor network is widely applied to military and civilian fields. But the security problem is always an important bottleneck which needs to be solved in wireless sensor networks, the current security mechanisms are mainly for single attack modes or certain stages of the attacks, and a complete security protection mechanisms for network running environment is not formed. To solve the problems, this paper presents a secure network running environment construction scheme for the wireless sensor networks. This scheme fully considers the computing power and energy of wireless sensor nodes, and it uses the static and dynamic measurement to protect the wireless sensor network combining the active and passive access control. The simulation results show that this scheme can effectively identify the malicious nodes with low energy consumption, while a few nodes under attack can ensure the whole network still runs normally.
