It is also known as Claude Shannon properties. Also discuss difference between Confusion and Diffusion. A Shannon cipher, invented by its namesake Claude Shannon (1916–2001) is a simplified cipher mechanism for encrypting a message using a shared secret key. A cipher is generally defined simply as an algorithm for performing encryption or decryption, i.e. “a series of well-defined steps that can be followed as a procedure”. There are two basic methods of encryption: Substitution and Permutation Properties of Claude Shannon: Confusion and Diffusion. It is also known as frustrate statistical cryptanalysis. What is Confusion? It is a technique of ensuring that a cipher text gives no clue about plain text. It is used in block and stream cipher method. Achieved by Substitution technique. Ex: ABC ⇒ XYZ What is Diffusion? Increases the redundancy of the plain text by spreading it across rows and columns. It is used in block cipher method. Achieved by permutation known as Transposition technique.
