Design of high speed advanced encryption standard using PPA and PPM

Abstract

Basically, internet security plays crucial role in past three decades. So in worldwide Advanced Encryption Standard (AES) algorithm is used. AES consists of symmetric block cipher blocks. In this paper we proposed the simplified AES algorithm (S-DES) using parallel prefix adder (PPA) and parallel prefix multiplier (PPM). This parallel prefix adder and parallel prefix multiplier will generate a product formed by multiplying the multiplicand. This algorithm possess specific structure to encrypt and decrypt delicate information and is connected in equipment and programming everywhere throughout the world. It is amazingly hard to programmers to get the genuine information while encoding the AES calculation. The fundamental goal of this algorithm is to build up a model that is executed for correspondence reason, and to test the created model regarding precision reason. The encryption procedure comprises the mix of different traditional methods, for example, substitution, improvement and change encoding strategies. At last the key extension module will comprise the quantity of iterative preparing rounds so as to expand its resistance against unapproved assaults.
