Encrypting Numbers Using Pair Labeling in Path Graphs

Abstract

Encryption today has grown into such specialized field that involve mathematical, non-linear cryptosystem that even a relatively powerful computers take months or even years to break the cipher text. Now a day's most of the fields say clients' credit card numbers, social security numbers, tax file numbers etc needs to be kept secret when they send it electronically. There are various methods used to encrypt the numbers. It has been recognized that encryption and decryption mostly emerges from mathematical disciplines. In this paper, we give a new combinatorial technique to encrypt and decrypt numbers through labeled graphs using the residue modulo class Z3.
