Abstract

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.

Description

technical field [0001] Apparatus and methods consistent with the present invention relate to sending and receiving digital rights objects (ROs) between a device and a portable storage in a converted format, and more specifically, to converting digital ROs received by a device from a rights issuer into a format in a certain The format communicates with the portable storage, and sends and receives the digital RO of the converted format, thereby reducing the load on the portable storage and improving data transmission efficiency. Background technique [0002] Recently, research and development on Digital Rights Management (DRM) has been actively conducted. Due to different characteristics of digital content, DRM has been used and will be used in commercial services. That is, unlike analog data, digital content can be copied losslessly, and can be easily reused, processed, and distributed with little cost to the copying and distribution of digital data...
