Wireless Sensor networks are often deployed in open environment, thus the networks can be susceptible to their unexpected physical environment and attacks from some adversaries. In addition, sensor devices are limited in resources and vulnerable to node capture, so even a few malicious adversaries can easily compromise sensor devices and inject forged data into the networks to make the networks...
