摘要

A method includes verifying (402) that firmware of a device (200) is trusted and contains a root of trust. The method also includes verifying (406) that a protected storage (214) of the device contains a private or secret key associated with a device certificate (DevCert) that is stored in a persistent storage (204, 210, 212) of the device. The method further includes verifying (414) the device certificate of the device using the root of trust. In addition, the method includes, in response to verifying that the protected storage contains the private or secret key associated with the device certificate and verifying the device certificate, determining that the device is a genuine device. The root of trust could include a trusted certificate or a trusted public key.
