Dispersion of Sequences for Generating a Robust Enciphering System

Abstract

This paper introduces a new paradigm for dispersion of information into three-dimensional space to generate a strenuous crypto system. The dispersion of the information is carried out by quaternion rotation matrix which is called quadripartite public-key (QPK). We considered a private key as a unit quaternion which has an arbitrary quadruple of real numbers. The public key has three different components which are constructed using quaternion rotation matrix QRM to generate a secure key, which significantly eliminates the risk of eavesdropping. Furthermore, quaternion has capability to provide a meditative encryption system for wireless images or voice transmissions. A computer-based simulation conducted to scrutinize the capability of QPK carefully in insuring the highest level of security is reported.
