Beaufort cipher. The Beaufort cipher, invented by some Giovanni Sestri in early 18th century but widely attributed to Sir Francis Beaufort, [1] is a substitution cipher similar to the Vigenère cipher, with a slightly modified enciphering mechanism and tableau. [2] Its most famous application was in a rotor-based cipher machine, the Hagelin M ...
"Soft-out" refers to the fact that each bit in the decoded output also takes on a value indicating reliability. Typically, the soft output is used as the soft input to an outer decoder in a system using concatenated codes , or to modify the input to a further decoding iteration such as in the decoding of turbo codes .
The CSA algorithm is composed of two distinct ciphers: a block cipher and a stream cipher. When used in encryption mode the data are first encrypted using the 64-bit block cipher in CBC mode, starting from packet end. The stream cipher is then applied from packet start. Block cipher. The block cipher process 64-bit blocks in 56 rounds.

A musical cryptogram is a cryptogrammatic sequence of musical symbols which can be taken to refer to an extra-musical text by some 'logical' relationship, usually between note names and letters. The most common and best known examples result from composers using musically translated versions of their own or their friends' names (or initials) as ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5. HMAC- SHA1.
