Abstract
A memory system includes an interface, a non-volatile memory and a controller. The interface is configured to communicate over an unsecured communication link with an external host. The non-volatile memory is pre-programmed with a device identifier and a corresponding initialization key that are additionally stored in a database that resides externally to the memory system, and is securely accessible by the host. The controller is configured to send the device identifier to the host, to receive from the host, via the interface, binding information that was generated in the host, to generate, using at least the received binding information and the pre-programmed initialization key, a first binding key that matches a second binding key that is generated in the host based on an initialization key securely obtained by the host from the database, and to securely communicate with the host over the communication link using the first binding key.
