Summary:A portable storage is provided. The storage includes a plurality of authentication modules (350-1,350-2...350-M) that perform mutual authentication using different mutual authentication algorithms; a control module (330) that controls the authentication modules (350-1,350-2...350-M) so that any one among the authentication modules (350-1,350-2...350-M) can perform mutual authentication work with a host device (200) through the DRM system identifier extracted from an authentication-request message received from the host device (200); and an object-management module (340) that protects communication with the host device (200) using a generated session key as a result of the mutual authentication.
