Abstract

A Learned Polyalphabetic Decryption Cipher

Highlights

Stamp [1] states that: ‘Cryptology is the art and science of making and breaking “secret codes”’
The hill climbing algorithm has had the ability to get very close to the correct key
This would suggest that using these keys for decryption would help a cryptanalysis to identify some words or letters in the cipher text

Summary

Introduction

Stamp [1] states that: ‘Cryptology is the art and science of making and breaking “secret codes”’. Martin [2] defines cryptology as a loosely used term to describe, ‘the design and analysis of mechanisms based on mathematical techniques’ to secure data and information. There are two types of studies in cryptology. “Cryptography” describes the fundamentals of securing data by using such mechanisms to design an algorithm [2][15]. “Cryptanalysis” is the opposite of cryptography and uses an ‘analysis of such mechanisms’ to decrypt its encryption [2][14]. Cryptology is a way of transforming an original message into cipher text that an interceptor may not be able to read and understand. The true recipient of the message could transform the message back to its original readable message by using a suitable decryption technique
