Abstract: A method for managing a replay protection memory block (RPMB) of a storage device includes allocating an RPMB master region managed separately from an RPMB region in which an RPMB key is stored in the RPMB of the storage device, programming a master key into the RPMB master region responsive to a request from a host, receiving a reset request for the RPMB region using the master key from the host, resetting the RPMB key in response to the reset request for the RPMB region, and receiving a reset lock request for the RPMB region from the host.
