Title
(EN) SECURE MONITORING USING BLOCK CHAIN
(FR) SURVEILLANCE SÉCURISÉE UTILISANT UNE CHAÎNE DE BLOCS
Abstract
(EN)
The present disclosure includes apparatuses, methods, and systems for using a local ledger block chain for secure updates. An embodiment includes a memory, and circuitry configured to receive a global block to be added to a local ledger block chain for validating an update for data stored in the memory, where the global block to be added to the local ledger block chain includes a cryptographic hash of a current local block in the local ledger block chain, a cryptographic hash of the data stored in the memory to be updated, where the current local block in the local ledger block chain has a digital signature associated therewith that indicates the global block is from an authorized entity.

La présente invention concerne des appareils, procédés et systèmes destinés à utiliser une chaîne de blocs de registre local pour des mises à jour sécurisées. Un mode de réalisation comprend une mémoire, et des circuits configurés pour recevoir un bloc global à ajouter à une chaîne de blocs de registre local pour valider une mise à jour de données stockées dans la mémoire, le bloc global à ajouter à la chaîne de blocs de registre local comprenant un hachage cryptographique d'un bloc local actuel dans la chaîne de blocs de registre local, un hachage cryptographique des données stockées dans la mémoire à mettre à jour, le bloc local actuel dans la chaîne de blocs de registre local possédant une signature numérique associée qui indique que le bloc global provient d'une entité autorisée.
