WebSep 30, 2001 · Basic concepts and results of that part of Information Theory which is often referred to as "Shannon Theory" are discussed with focus mainly on the discrete case. The paper is expository with some new proofs and extensions of results and concepts. WebCryptography is the science of protecting information by transforming it into a secure format. An example of basic cryptography is a encrypted message in which letters are replaced with other characters. To decode the encrypted contents, you would need a grid or table that defines how the letters are transposed. What is the purpose of cryptography?
