摘要: La présente description concerne un circuit (112) configuré pour :
- effectuer une opération entre une mémoire (120) et un circuit cryptographique (116) en réponse à une demande d'accès en écriture d'une ou plusieurs données vers la mémoire, la demande d'accès comprenant en outre une adresse de stockage dans la mémoire, l'opération comprenant :
l'écriture de la ou des données ; et
pour chacune des données, la génération d'une demande d'accès pour écriture, dans le circuit cryptographique, de la donnée et la génération d'une demande d'accès pour écriture, dans le circuit cryptographique de l'adresse de stockage ;
- effectuer une vérification, en réponse à une demande d'accès pour lecture, en provenance du processeur, d'une valeur de vérification, la vérification comprenant :
la comparaison de la valeur de vérification avec une valeur de référence ; et
- sur la base de la comparaison, l'autorisation d'accès à la mémoire uniquement en lecture.-

摘要: An account management system receives, from a user computing device, a request for a virtual access card and a user account identifier associated with an account hub system account. The system receives, from the account hub computing system, account hub system account metadata associated with the user account hub system account. The system transmits, to the account hub computing system, a request for an access card identifier and a virtual access payload. The system receives, from the account hub computing system, the access card identifier and the virtual access payload. The system provides, to the user computing device, the access card identifier and the virtual access payload, the user computing device communicating the access card identifier and the virtual access payload to a reader computing device via a wireless communication channel.

摘要: A method and system for multi-factor authenticating users in Web3 services comprising a multi-factor authentication (e.g., 2FA) provider (122) configured to validate that an end-user (110) owns a public key in a blockchain based on a cryptocurrency or a NFT transference, the public key used as a first factor for the authentication. The authentication provider (122) interacts with a smart contract to perform the multi-factor authentication in an operation in a smart contract by using off-chain data as the other factor(s) required for the multi-factor authentication. The off-chain data are received in a user terminal, e.g., a smartphone (208) via SMS or a mobile application, associated with the account created in the authentication provider (122). The authentication result is read by each node executing the smart contract and, when a consensus (216) is reached among nodes, a new block (C) representing the result is generated in the blockchain.
