Title
(EN) METHODS AND APPARATUS FOR PERFORMING A CRYPTOGRAPHIC OPERATION WITH A KEY STORED IN A HARDWARE SECURITY MODULE
(FR) PROCÉDÉS ET APPAREIL POUR EFFECTUER UNE OPÉRATION CRYPTOGRAPHIQUE À L'AIDE D'UNE CLÉ STOCKÉE DANS UN MODULE DE SÉCURITÉ MATÉRIEL
Abstract
(EN) Aspects of the present disclosure relate to an apparatus comprising secure enclave circuitry, and processing circuitry to execute computer program instructions. The computer program instructions correspond to an operation comprising accessing a cryptographic key, the key being stored in a hardware security module. Executing the computer program instructions comprises transmitting, to the secure enclave circuitry, computer program instructions corresponding to said operation. The secure enclave circuitry is configured to initiate communication with the hardware security module, perform, with the hardware security module, an attestation process in respect of said operation, and execute said operation.
(FR) Des aspects de la présente divulgation concernent un appareil comprenant des circuits d'enclave sécurisée, et des circuits de traitement pour exécuter des instructions de programme informatique. Les instructions de programme informatique correspondent à une opération consistant à accéder à une clé cryptographique, la clé étant stockée dans un module de sécurité matériel. L'exécution des instructions de programme informatique consiste à transmettre, aux circuits d'enclave sécurisée, des instructions de programme informatique correspondant à ladite opération. Les circuits d'enclave sécurisée sont configurés pour initier une communication avec le module de sécurité matériel, pour effectuer, avec le module de sécurité matériel, un processus d'attestation en ce qui concerne ladite opération, et pour exécuter ladite opération.
