Abstract

La présente invention concerne un protocole permettant d'interdire toute répudiation de la part de parties prenantes à une transaction électronique exécutée, dans laquelle une tierce partie de confiance est responsable et fait en sorte que cette non-répudiation soit respectée. Dans ce protocole, un expéditeur utilise une technologie secrète partagée de façon à diviser la clé de session originale en une première clé de sous session et en une seconde clé de sous session. Ces première et seconde clés de sous session doivent être combinées dans la clé de session originale de sorte qu'un destinataire puisse décrypter un produit crypté avec cette clé de session originale. L'expéditeur inclut la première clé de sous session cryptée avec une clé publique du destinataire, ainsi qu'un produit crypté dans un premier message. L'expéditeur transmet ensuite ce premier message au destinataire. Ce destinataire utilise ce premier message comme preuve de non-répudiation à l'émission, c'est à dire comme preuve que l'expéditeur a bien envoyé la transaction. Le destinataire transmet à l'expéditeur un deuxième message dans lequel il demande la seconde clé de sous session. L'expéditeur peut utiliser ce deuxième message comme preuve de non-répudiation à la réception, c'est à dire comme preuve que le destinataire a bien reçu la transaction. Enfin l'expéditeur inclut la seconde clé de sous session cryptée avec la clé publique de la tierce partie de confiance dans un troisième message qui est envoyé à la tierce partie de confiance.
