Wireless Sensor Networks (WSN) is an emerging technology and day-by-day it is attracting the attention of researchers with its challenging characteristics. The more researchers try to develop further cost and energy efficient computing devices and algorithms for WSN, the more challenging it becomes to fit the security of WSN. Security is crucial to the success of applying WSN. The paper studies different protocols designed for security of WSN with Broadcast Authentication and also documents their drawbacks. The paper also describes the efficient algorithm designed for Broadcast Authentication which is the main security requirement in WSN.
