An Ultra Lightweight Encryption Design for Security in Pervasive Computing

Abstract

This paper proposes an ultra light weight cipher ANU. ANU is 25 round lightweight cipher which supports 80/128 bit key scheduling. It needs only 934 GEs for 128 bit key which is very less as compared to all existing cipher. ANU cipher design shows good resistance against basic and advanced attacks. This paper furnishes security analysis of the ANU cipher. ANU design not only results in small footprint area but it also consumes very less power. ANU design will be best suitable for applications like IoT, Wireless sensor nodes where memory and power consumption are the major constraints.
