In cryptography, 3-Way is a block cipher designed in 1994 by Joan Daemen. It is closely related to BaseKing; the two are variants of the same general cipher technique. 3-Way has a block size of 96 bits, notably not a power of two such as the more common 64 or 128 bits. The key length is also 96 bits. The figure 96 arises from the use of three 32 bit words in the algorithm, from which also is derived the cipher's name. When 3-Way was invented, 96-bit keys and blocks were quite strong, but more recent ciphers have a 128-bit block, and few now have keys shorter than 128 bits. 3-Way is an 11-round substitution–permutation network.

| - 3-Way ist eine Blockchiffre, die 1994 von Joan Daemen erfunden wurde. Sie hat eine Block- und Schlüssellänge von 96 Bit. 3-Way kann mit einer beliebigen Anzahl an Runden durchgeführt werden; der Entwickler empfiehlt elf Runden. Ein Ziel bei der Entwicklung der Blockverschlüsselung war es, eine effiziente Implementierung in Hardware zu ermöglichen. Im Jahr 1997 wurde entdeckt, dass 3-Way gegenüber einer „Related-key attack“ anfällig ist. (de)

- 3-Way est un algorithme de chiffrement par bloc conçu en 1994 par Joan Daemen et publié dans sa thèse. 3-Way emploie un bloc avec une taille inhabituelle de 96 bits, soit 3 mots de 32 bits (d'où le nom de 3-Way). La clé a également une taille de 96 bits. Lors de sa conception, ces valeurs paraissaient suffisamment robustes contre les attaques mais depuis, les algorithmes basés sur des clés de 128 bits sont devenus légion. 3-Way comprend 11 tours d'un réseau de substitution-permutation.

John Kelsey, Bruce Schneier, and David Wagner showed how it can be broken with one related key query and about chosen plaintexts. (en)

L'algorithme a été conçu de manière à être implémenté dans du matériel avec un schéma de déchiffrement qui est très proche du chiffrement de manière à économiser les ressources. 3-Way est vulnérable à une attaque par clé apparentée que l'on doit à John Kelsey, Bruce Schneier et David Wagner et dont la complexité est de l'ordre de 222 textes clairs choisis.
