RS Dynamic Encryption (A Dynamic Encryption Technique)

Abstract

This paper presents the encryption/decryption technique where dynamism is exploited. The method of encryption is simple enough yet powerful enough to fit the needs of students and staff in a small institution. The application uses random number generator for generating dynamic keys. The final encryption is performed through the rotation of each of the bits by the random number generated by the random number generator. The result after rotation and the random keys are mapped to a graph containing a curve (sine, cosine, etc.) and their displacement from the curve are determined. The displacements are rotated in opposite direction according to the same random keys. The rotated displacements form the encrypted text.
