Wireless Sensor Networks (WSN) have recently been in the limelight for many domains. WSN are useful in data collection, event detection or entity tracking applications. The characteristics of sensor networks have imposed various restrictions on their

传感器网络安全现状、面临的安全挑战及其需要解决的安全问题。-The current situations of sensor network security, the security challenges and the security problems were pre- sented.

Wireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or more sensor nodes and reveal all stored security information which enables him to compromise a part of the WSN communications. Due to lar
