Title
(EN) DATA ATTESTATION IN MEMORY
(FR) ATTESTATION DE DONNÉES EN MÉMOIRE
Abstract
(EN)
The present disclosure includes apparatuses, methods, and systems for data attestation in memory. An embodiment includes a memory, and circuitry configured to detect a power off of the apparatus, generate a run-time cryptographic hash, and compare the run-time cryptographic hash with a cryptographic hash in response to detecting the power off, wherein the cryptographic hash is stored in a portion of the memory.

La présente invention concerne des appareils, des procédés, et des systèmes d'attestation de données en mémoire. Un mode de réalisation comprend une mémoire et des circuits configurés pour détecter une mise hors tension de l'appareil, générer un hachage cryptographique en temps d'exécution, et comparer le hachage cryptographique en temps d'exécution à un hachage cryptographique en réponse à la détection de la mise hors tension, le hachage cryptographique étant stocké dans une portion de la mémoire.
