Implementation of LiSP using Park-Miller for Wireless Sensor Network

Abstract

Wireless sensor networks continuous to grow and a rosining technology in networks. WSN used in many critical situations and applications. One of major application of the sensor network is use in military. Due to these reason securities is a major challenge for WSN. Wireless sensor networks have many topics to do the research but security plays an important role in data and network security. In the present work, author use the block cipher rather than stream cipher, and key to perform encryption and decryption operation to create lightweight security protocol. Encryption algorithm takes two inputs, one is the text enter by the user another one is the dynamic key. Dynamic key has one most important advantage is that for each pair of the encryption and decryption new key is generated and previous one is discarded. In this paper dynamic key is generated by using park-miller random number generator. In the present work the key of 196 bits is used. This key is mainly used to convert the text entered by the user into the unreadable form. In this paper author divides the input plaintext into 49 bits of blocks. Dynamic key is following the concept of one time pad. Different key is used for the different parts of the plaintext so it is difficult and make it harder to break the security of data.
