A Survey on Lightweight Block Ciphers for Wireless Sensor Network.

With an advancement of wireless communication technology, wireless sensor network (WSN) has emerged as one of the most powerful technologies which can be used in various applications, such as military surveillance, environment monitoring, industrial control, and medical monitoring. Wireless Sensor Network includes many devices such as smart grids, mobile phones, RFID tags, smart cards and micro- chips etc which need limited resources.. In this paper, the summary of Wireless Sensor Network has been given. After that the requirement for the WSN security and various attacks on the WSN are briefly discussed. This paper depicts the various block ciphers which helps to resolve the attacks of Wireless Sensor Network and comparison of various block ciphers had also been done. [ABSTRACT FROM AUTHOR]
