Abstract
A method for securing access to a data storage device (DSD), comprising: receiving, from a host connected to a data port of the DSD, a data access request to access user data stored on the DSD. In response to receiving the data access request, the DSD transmits, to the host, a Long Term Device Key (LTDK) of the DSD and a session identifier uniquely generated for the data access session. An access token is received from the host, signed by a private Long Term Host Key (LTHK) of the host. The LTHK and the LTDK form a cryptographic pair. The access token is validated using the LTDK to determine whether the host is authorized to access the DSD. In response to determining that the host is authorized to access the DSD, a data access state of the DSD is set to an unlocked state to enable access to the user data by the host via the data port, wherein the LTDK is obtained from a registration token transmitted to the DSD by the host. The registration token is secured by a registration server in response to the registration of the host with the DSD.
