Securing Wireless Sensor Networks: Security Architectures

Wireless sensor networking remains one of the most exciting and challenging research domains of the time. As technology progresses, so do the capabilities of sensor networks. Limited only by what can be technologically sensed, it is envisaged that wireless sensor networks will play an important part in one daily lives in the foreseeable future. Privy to many types of sensitive information, both sensed and disseminated, there is a critical need for security in a number of applications related to this technology. Resulting from the continuous debate over the most effective means of securing wireless sensor networks, this paper considers a number of the security architectures employed, and proposed, to date, with this goal in sight.
