WebKerckhoffs' surviving principle nr. 2 (of initially six design principles for military ciphers) says nothing else than that you have to look at the security of your crypto under the aspects of "the enemy knows the algorithm" and maybe even "the enemy carries the message". WebA block cipher is one in which a block of plaintext is treated as a whole and used to produce a ciphertext block of equal length. Typically, a block size of 64 or 128 bits is used. Using …

WebA cipher algorithm is a mathematical formula designed specifically to obscure the value and content of data. Most valuable cipher algorithms use a key as part of the formula. This … Kerckhoffs viewed cryptography as a rival to, and a better alternative than, steganographic encoding, which was common in the nineteenth century for hiding the meaning of military messages. One problem with encoding schemes is that they rely on humanly-held secrets such as "dictionaries" which disclose for example, the secret meaning of words. Steganographic-like dictionaries, once revealed, permanently compromise a corresponding encoding system. Anoth… onsted ocrc
