A Hardware Implementation of Lightweight Block Cipher for Ubiquitous Computing Security

Abstract

Ubiquitous Computing applications have resource constraints and conventional block ciphers are infeasible to meet their requirements. This paper presents a hardware design and implementation of lightweight block cipher based on Reversible Cellular Automata (RCA), which is able to generate high pseudo random patterns with low computational overheads. The prototype implementation shows that the total number of gate is less than 3k and operates for 400 clock cycles in 82.156 MHz and it outperforms AES and NTRU. In addition, the cryptanalysis including Strict Avalanche Criterion (SAC), Differential Cryptanalysis (DC) and Linear Cryptanalysis (LC) to our implementation is satisfied.
