FPGA implementation of Katan block cipher for security in wireless sensor networks

Abstract

In this paper we are going to design an efficient and enhanced low weight cipher algorithm for multipurpose applications. A number of new factors like limited computational power, RAM size, ROM size, register width, different operating environment and etc., constrained WSN (Wireless Sensor Networks) to use traditional security measures. These constraints on Wireless sensor networks enabled devices results in the emergence of a new field, Lightweight Cryptography. Recently a number of software and hardware implementation of lightweight ciphers are designed for Wireless sensor networks applications. To attain the declared objective, we choose a single cipher only. Which is specifically the KATAN light-weight block cipher algorithm and it needed to be modeled, implement and optimize on specific XILINX ISE platform.
