Survey of Security Technologies on Wireless Sensor Networks

Because of their low cost and adaptability,wireless sensor networks are widely used in civil,military,and commercial fields and other fields. however,since the sensor node in the calculation of the capacity,battery capacity,and storage capacity are restricted by the limitations and inherent characteristics of the sensor networks,compared to traditional networks,which makes wireless sensor networks face more security threats. this paper summarized research progress of sensor network security issues as three aspects,key management,authentication,and secure routing,analyzed and commented on these results advantages and disadvantages and pointed out the future direction of the hot research field. © 2015 qiuwei yang et al.
