High-performance Block Cipher Using Flexible Architecture

Abstract

Light weight cryptography has been a prominent sector in exploring the cryptanalytics in contemporary world. In this paper, an elevated production capable structure and pliant implementations of hardware by SPECK, which is a lightly weighted block cipher is presented. This lightly weighted SPECK can be accustomed to diminish the retardation of critical path, a tree structure for the realization of Sklansky adder which is an efficient parallel prefix adder operation is used.
