Title (EN) ESTABLISHMENT OF A TRUSTED RELATIONSHIP BETWEEN UNKNOWN COMMUNICATION PARTIES
(FR) ETABLISSEMENT D'UNE RELATION DE CONFIANCE ENTRE DES PARTIES INCONNUES A UNE SESSION DE COMMUNICATION
Abstract: front page image
(EN)The present invention provides an establishment of a trusted relationship between two mutually unknown communication parties in a communication system without the use of a trusted third party. The invention is based on non-interactive proofs-of-work being purpose-bound for establishing the trusted relationship and cryptographically signing information to be transferred between the communication parties using such proofs-of- work for the solving of a problem instance along with verifying the proofs-of-work and generating a session object for a trusted relationship, when the verifying yields an affirmative result.
(FR)Cette invention concerne l'établissement d'une relation de confiance entre deux parties à une session de communication inconnues l'une à l'autre dans un système de communication, sans le recours à une tierce partie de confiance. Cette invention se base sur des preuves d'action non interactives qui sont spécialement conçues pour établir la relation de confiance et sur la signature cryptographique d'informations devant être transférées entre les parties à la session de communication au moyen de ces preuves d'action, pour résoudre un problème ponctuel, ainsi que sur la vérification de ces preuves d'action, un objet de session étant généré pour une relation de confiance, lorsque l'opération de vérification produit un résultat affirmatif.
