e/LEVIATHAN (cipher)

Information
has gloss	eng: LEVIATHAN is a stream cipher submitted to NESSIE by Scott Fluhrer and David McGrew. It is a seekable stream cipher, which means that the user may efficiently skip forward to any part of the keystream, much like CTR mode or Salsa20, but unlike those ciphers generating contiguous blocks of the keystream is made especially efficient by LEVIATHAN's unique tree structure based stream generation. LEVIATHAN achieves around 11 cycles per byte on a Pentium II processor.

Meaning
French
has gloss	fra: LEVIATHAN est un algorithme de chiffrement de flux soumis au projet NESSIE par Scott Fluhrer et David McGrew. Il sagit dun chiffrement de flux « accessible » (seekable stream cipher), ce qui signifie que lutilisateur peut efficacement avancer jusquà nimporte laquelle des parties de la clé de chiffrement, comme le mode dopération CTR ou le Salsa20 ; mais contrairement à ces méthodes de chiffrement, LEVIATHAN génère de manière particulièrement efficace les blocs continus constituant la clé grâce à la structure en arbre de la génération du flux des bits de la-dite clé.
