Abstract
(EN)
An apparatus including non-volatile memory to store a forensic key and data, the data received from a host computing system. A processing device is coupled to the non-volatile memory and is to: allow writing the data, by the host computing system, to a region of the non-volatile memory; in response to a lock signal received from the host computing system, assert a lock on the region of the non-volatile memory, the lock to cause a restriction on access to the region of the non-volatile memory by an external device; and provide unrestricted access, by the external device, to the region of the non-volatile memory in response to verification of the forensic key received from the external device.
(FR)
Selon l'invention, un appareil comprend une mémoire permanente pour stocker une clé et des données médico-légales, lesdites données provenant d'un système informatique hôte. Un dispositif de traitement est couplé à la mémoire permanente dans le but : d'autoriser le système informatique hôte à écrire les données dans une zone de la mémoire permanente; d'appliquer un verrou sur la zone de la mémoire permanente, en réponse à un signal de verrouillage reçu du système informatique hôte, ledit verrou visant à restreindre l'accès d'un dispositif externe à la zone de la mémoire permanente; et d'autoriser un accès non restreint du dispositif externe à la zone de la mémoire permanente, après vérification de la clé médico-légale reçue du dispositif externe.
