Abstract

La présente invention concerne un procédé et un appareil de transmission sécurisée d'un signal optique contenant de l'information. On divise un signal optique en une première pluralité de sous-bandes dont chacune est modifiée pour crypter l'information contenue dans le signal optique. On combine les sous-bandes modifiées en un signal optique combiné. On divise ce signal en une seconde pluralité de sous-bande dont chacune est modifiée pour décrypter l'information préalablement cryptée contenue dans le signal optique.
