A system and method for exchanging secure information between Secure Removable Media (SRM) devices. An initialization operation is performed between the SRM devices. After a mutual authentication operation is performed between the SRM devices, a secret key is exchanged for secure information exchange. An installation setup operation is then performed to establish an environment for moving rights between the SRM devices, and the rights information can be directly exchanged between the SRM devices by performing a rights installation operation between the SRM devices.

An apparatus and method for determining contents information corresponding to a Rights Object (RO) by transmitting information on contents together when the RO is moved from a mobile device to a memory card or a smart card or when the RO is moved from the memory card or the smart card to the mobile device are provided. The apparatus includes a meta information manager for determining information on contents corresponding to the RO when the RO is moved, and for generating meta information containing the determined contents information, and a controller for providing control to transmit the RO and the meta information generated by the meta information manager to a portable storage device. Accordingly, the conventional problem can be solved in which information on contents cannot be determined by using a Contents IDentifier (CID) if the RO does not exist together with the contents.
