LEA 192: High Speed Architecture of Lightweight Block Cipher

Abstract

High-throughput lightweight cryptography calculation is the need of the present world to convey between two asset obliged devices Pipelining is the technique have been used to achieve high throughput. In this paper we have target to lightweight block cipher LEA. Block size of LEA is 128 and key size 128, 192, and 256 bit. In this paper we have focus on LEA architecture for 192- bit key size and achieve very good throughput. This method has a higher capability of throughput as compared to previous LEA ciphers. Proposed work is 56% improved version of compared paper for respective Speed and area also less than previous architecture. Graph representation have been shown of different matrices and comparison.
