DEF

Dispositif de cryptographie militaire fonctionnant selon le principe de transposition et consistant en un ruban de parchemin enroulé en spires jointives autour d'un bâton.

OBS

Après avoir enroulé [le parchemin sur le bâton], le message était écrit en plaçant une lettre sur chaque circonvolution. Pour le déchiffrer, le destinataire devait posséder un bâton d'un diamètre identique à celui utilisé pour l'encodage. Il lui suffisait alors d'enrouler [le parchemin] autour de ce bâton pour obtenir le message en clair.
