A New Encryption Scheme Involving Spiral Rotation Technique Alongwith Aryabhata’s Substitution Code

Abstract

The aim of this paper is to propose a new encryption scheme involving Spiral Rotation Technique and Aryabhata’s Substitution Code. The ‘Spiral Rotation Technique’ is applied on a matrix representation of data, and ‘Aryabhata’s Substitution Code’ is a plotting of numbers to words. The ‘Byte Rotation Technique’ is applied on different blocks of plaintext. In a single processor system, multithreading helps run multiple tasks at the same time. Thus, this type of encryption method produced a new encryption model and creates a double security system which is very fast and secure.
