RAGHAV: A new low power S-P network encryption design for resource constrained environment

GAURAV BANSOD

Abstract

This paper proposes a new ultra lightweight cipher RAGHAV. RAGHAV is a Substitution-Permutation (SP) network, which operates on 64 bit plaintext and supports a 128/80 bit key scheduling. It needs only 994.25 GEs by using 0.13µm ASIC technology for a 128 bit key scheduling. It also needs less memory i.e. 2204 bytes of FLASH memory , which is less as compared to all existing S-P network lightweight ciphers. This paper presents a complete security analysis of RAGHAV, which includes basic attacks like linear cryptanalysis and differential cryptanalysis. This paper also covers advanced attack like zero correlation attack, Biclique attack, Algebraic attack, Avalanche effect, key collision attack and key schedule attack. In this cipher,use of block permutation helps the design to improve the throughput. RAGHAV cipher uses 8 bit permutations with S-Box which results in better diffusion mechanism. RAGHAV consumes very less power around 24mW which is less as compared to all existing lightweight ciphers. RAGHAV cipher scores on all design metrics and is best suited for applications like IoT.
