Title (EN) DEVICES AND METHOD OF OPERATION THEREOF
(FR) DISPOSITIFS ET LEUR PROCÉDÉ DE FONCTIONNEMENT
Abstract:
(EN) A device comprising : a processing element; a data store, coupled to the processing element, the data store comprising a non-volatile data store having a trusted region for trusted code and an untrusted region for untrusted code; a security component, coupled to the processing element and the data store, wherein the security component is configured to, in response to one of a power event occurring at the device and receiving a trigger signal, send a first signal to the processing element and the data store, and wherein the processing element is configured to execute trusted code in response to the first signal.
(FR) L'invention concerne un dispositif comprenant : un élément de traitement ; un magasin de données connecté à l'élément de traitement, le magasin de données comprenant un magasin de données non volatile ayant une région de confiance pour un code de confiance et une région non fiable pour un code non fiable ; un composant de sécurité, connecté à l'élément de traitement et au magasin de données. Le composant de sécurité est configuré pour, en réponse à l'un parmi un événement d'alimentation se produisant au niveau du dispositif et la réception d'un signal de déclenchement, envoyer un premier signal à l'élément de traitement et au magasin de données, et l'élément de traitement est configuré pour exécuter un code de confiance en réponse au premier signal.
