Title
(EN) COMPUTER-IMPLEMENTED SYSTEM AND METHOD FOR FACILITATING TRANSACTIONS ASSOCIATED WITH A BLOCKCHAIN USING A NETWORK IDENTIFIER FOR PARTICIPATING ENTITIES

Abstract
(EN)
The present disclosure proposes methods and devices for facilitating IP transaction involving digital assets over the Internet directly based on IP addresses for entities. The aspects and embodiments of the present disclosure enable secure IP address transactions by ensuring that the public key of the recipient is never used in the generation of payment destination addresses, thereby making message replay and MITM attacks extremely hard to implement by an attacker. Furthermore, the aspects and embodiments ensure that the payment destination addresses for digital assets are based on new or single use private as well as public keys that are computed or provided based on the public key for the recipient and are specific to a given transaction.

La présente invention concerne des procédés et dispositifs servant à faciliter une transaction par IP impliquant des biens numériques sur Internet directement sur la base d'adresses IP destinées à des entités. Les aspects et modes de réalisation de la présente invention permettent des transactions sécurisées par adresses IP en garantissant que la clé publique du destinataire n'est jamais utilisée pour générer des adresses de destination de paiement, ce qui complique extrêmement pour un attaquant la réalisation d'une relecture de messages et d'attaques d'intercepteur. En outre, les aspects et les modes de réalisation garantissent que les adresses de destination de paiement pour les biens numériques sont basées sur des clés privées nouvelles ou uniques aussi bien que sur des clés publiques qui sont déterminées par calcul ou fournies sur la base de la clé publique destinée au destinataire et qui sont spécifiques à une transaction donnée.
