Supplanted by Cryptography Engineering. [4] [5] [6] Smart, Nigel (2004). Cryptography: An introduction ISBN 0-07-709987-7. Similar in intent to Applied Cryptography but less comprehensive. Covers more modern material and is aimed at undergraduates covering topics such as number theory and group theory not generally covered in cryptography books.

Blowfish is a block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products. Blowfish has a 64-bit block size and a variable key length from 1 bit up to 448 bits. [45] It is a 16-round Feistel cipher and uses large key-dependent S-boxes.
All algorithms support authenticated encryption with plaintext P and additional authenticated data A (that remains unencrypted). The encryption input also includes a public nonce N, the output - authentication tag T, size of the ciphertext C is the same as that of P. The decryption uses N, A, C, and T as inputs and produces either P or signals ...
ICE is a 16-round Feistel network.Each round uses a 32→32 bit F function, which uses 60 bits of key material. The structure of the F function is somewhat similar to DES: The input is expanded by taking overlapping fields, the expanded input is XORed with a key, and the result is fed to a number of reducing S-boxes which undo the expansion.
The length of this bit string is the block size. [1] Both the input ( plaintext ) and output ( ciphertext ) are the same length; the output cannot be shorter than the input – this follows logically from the pigeonhole principle and the fact that the cipher must be reversible – and it is undesirable for the output to be longer than the input.
The Encyclopedia of Cryptography and Security is a comprehensive work on Cryptography for both information security professionals and experts in the fields of Computer Science, Applied Mathematics, Engineering, Information Theory, Data Encryption, etc. [1] It consists of 460 articles in alphabetical order and is available electronically and in print.
