METHOD OF UNLOCKING A SECURE DEVICE AND DEVICE

摘要

The invention relates to a terminal (MT) suitable for receiving an embedded card (CSD) comprising a first security element (SE_CSD) suitable for providing encryption keys (K_ENC), said terminal (MT) comprising: - a sensor (FP) suitable for sensing a digital fingerprint (DG) and for extracting the minutia therefrom (MIN) - a keyboard (KB) allowing the entry of a security code (K_STG) - a module (STG) comprising : o a second security element (SE_STG) comprising reference minutia (MIN_REF) and a reference access code (K_CSD_REF) for access to the first embedded security element (SE_CSD) o a biometry application (BM) suitable for analyzing the minutia (MIN) originating from the sensor (FP), and comparing them with the reference minutia (MIN_REF) o means for dispatching the reference access code (K_CSD_REF) to the first security element (SE_CSD) if the minutia (MIN) correspond to the reference minutia (MIN_REF) o means of computation suitable for computing an access code (K_CSD) as a function of a security code (K_STG) received from the keyboard (KB), and comparing said access code (K_CSD) with the reference access code (K_CSD_REF) o means of dispatching the computed access code (K_CSD) to the first security element (SE_CSD).
