Acrónimos: FEAL
Familia de algoritmos en bloque diseñada por A. Akihiro y S. Miyaguchi para NTT Japón. Transforma en N vueltas, de modo similar al DES, una entrada de 64 bits. Es importante en el desarrollo de técnicas criptoanalíticas [CESID:1997]
(O) A family of symmetric block ciphers that was developed in Japan; uses a 64-bit block, keys of either 64 or 128 bits, and a variable number of rounds; and has been successfully attacked by cryptanalysts. [Schn] [RFC4949:2007]
The Fast Data
Encipherment Algorithm is a family of algorithms that maps 64 plaintext to
64-bit ciphertext blocks under a 64-bit secret key. It is similar to DES but
with a far simpler ffunction. It was designed for speed and simplicity, making
it suitable for less complex microprocessors (e.g. smartcards).
