    摘要: A host device and a method of implementing Digital Rights Management (DRM) systems in a low-efficiency storage device are provided. The host device includes a plurality of DRM systems and a DRM system-shared interface module. The DRM systems provide pieces of DRM-related data and data identifiers (IDs) which identify the pieces of data. The DRM system-shared interface module adds DRM system IDs, which are used to identify the DRM systems, to the pieces of data and the data IDs, and provides results, which are obtained by adding the DRM system IDs, to a low-efficiency storage device.

    摘要: A method and apparatus for implementing a secure clock having no internal power source are disclosed. The apparatus accesses a host device having an internal power source and transmits and receives data. The apparatus includes a clock control unit, a counter, and a time information unit. The clock control unit performs control such that the time information of the host device is acquired and a counter value corresponding to the acquired time information is set, when the clock control unit is connected to the host device and is supplied with power from the host device. The counter changes the set counter value in steps of a predetermined value at regular time intervals while the power is supplied. The time information unit updates current time information to correspond to the changed counter value while the power is supplied.

    摘要: A method for moving a rights object (RO) between devices, a method of using a content object based on the moving method, and devices using the methods are provided. The moving method includes performing authentication between two devices; securing a connection between the devices; and communicating the rights object between the two devices. The using method includes two devices communicating with each other, the first device having use permission of content objects and the second device including the content objects and corresponding rights objects; the first device searching for the content objects; and the first device using the content object that was found. The device includes an authentication module to authenticate another device; a security formation module to secure a connection for the other device; and a transceiving module which communicates a rights object for which the connection has been secured.

    摘要: An apparatus and method for sending and receiving a digital rights object (RO) in a converted format between a device and a portable storage are provided. The device includes a transceiver module receiving a RO from a rights issuer, an RO converter module converting the RO received by the transceiver module into a format for communication with a portable storage, an interface module for connection with the portable storage, a public-key encryption module authenticating with the portable storage connected through the interface module, a session key generation module generating a session key shared with the authenticated portable storage, and a digital rights management (DRM) agent providing the RO in the format converted by the RO converter module to the portable storage and receiving a RO in the converted format from the portable storage. The device converts the format of the RO to communicate with the portable storage.
