This article provides a general introduction to the subject of Cryptology, Crytography and Crytoanalysis and explains the terminology and the practical application of security techniques… In recorded History , technological innovations have revolutionized societies. The printing press is an often-cited example of the great impact one humble person's invention can have on ruling dynasties, world religions, and personal life.. Quantum encryption could rival Guttenberg's printing press in its impact. Cryptology has a fascinating History., In Warfare Cryptography is a broad, sticky, and mathematically complex, but interesting subject and an integral part of the evolution of warfare. So let's get some definitions out of the way first. Cryptology is the study of codes, both creating and solving them. Cryptography is the art of creating codes. Cryptanalysis is the art of surreptitiously revealing the contents of coded messages, breaking codes, that were not intended for you as a recipient.. Secondly, there are nomenclators and enciphers. Nomenclators are letters or numbers that represent words or phrases, like 103A means "meet me at 4PM". Ciphers are alphabetical letters or numbers that are encrypted using some sequential coding process and a key. For this essay, we will refer to both as codes. Also, enciphered, encrypted and encoded mean the same thing….Additionally, there is plain text. This is the original message that is readable and understandable, uncoded or unencrypted. Once it goes through the coding process and is encrypted, the output is readable but not understandable. There are a bunch of other terms like steganography, homophones, polyphones, digraphs, bigrams, and polygrams, but they are just variations of coding and decoding techniques. KEYWORDS Network Protocols, Mathematical Cryptology, encryption, decription 1. CRYPTOLOGY The study of cryptography and cryptanalysis. Cryptology is the mathematics, such as number theory, and the application of formulas and algorithms, that underpin cryptography and cryptanalysis. Since the cryptanalysis concepts are highly specialized and complex, we concentrate here only on some of the key mathematical concepts behind cryptography. cryptology is made up of cryptography and cryptanalysis. 1) Crytography-The art and science of making ciphers. Which concerns with the design of the cryptosystems and cryptography, is the actual securing, control, and identification of digital data. 2) Crytoanalysis-The art and science of breaking ciphers. In other words, the extraction of mm given cc, EE, DD, and possibly keke. which aims at studies relating to breaking of cryptosystems. cryptanalysis, is made up of all the attempts one might develop to undermine, circumvent, and/or break what the first part, cryptography, is attempting to accomplish. 3) Cryptosystems:-A particular suite of algorithms and protocols for encryption, decryption, and key generation. Examples: Cramer-Shoup cryptosystem, Rabin cryptosystem, Benaloh cryptosystem, RSA cryptosystem.
