Abstract

L'invention porte sur un réseau de télécommunications (10) comportant un nombre quelconque de noeuds (20) interconnectés dont un noeud émetteur (22), une passerelle d'émission, une passerelle de réception, et un noeud de destination (28). Un canal de transmission (30) à faible capacité ou d'une exploitation coûteuse relie les passerelles d'émission et de réception (24, 26). Un message à signature numérique d'origine est émis par le noeud émetteur (22) vers le noeud de destination (28). Lorsque le message d'origine arrive à la passerelle d'émission (24), la signature d'origine est vérifiée. Si la vérification est positive, la passerelle d'émission comprime le message en un message réduit et le resigne avec une signature numérique de passerelle avant de le retransmettre au noeud de destination (28) par l'intermédiaire du canal (30). Le noeud de destination (28) vérifie la signature numérique de passerelle en la comparant avec le message réduit sans avoir à décomprimer le message réduit pour en faire un duplicata exact du message d'origine.
