摘要：A wireless sensor network (WSN) is a spatially distributed autonomous sensors to monitor and cooperatively report information about physical or environmental conditions, such as temperature, sound, pressure, etc. through the network to a server machine. WSNs are generally implemented for collecting information from insecure environment. Nearly all security protocols for WSN believe that the intruder can achieve entirely control over a sensor node by way of direct physical access. The appearance of sensor networks as one of the main technology in the future has posed various challenges to researchers. The challenges thrown by WSNs are unique given their delicate architecture and scant resources. Even though security for wireless networks has been a widely researched area for many decades, security for WSNs is still a major roadblock for their efficiency and performance.
