Apparatus and method for sending and receiving digital rights objects in converted format between device and portable storage
First Claim
1. A device comprising:
- a transceiver module which receives a rights object from a rights issuer;
a rights object converter module which converts the rights object received by the transceiver module into a converted format for communication with a portable storage;
an interface module which is connectable to the portable storage;
a public-key encryption module which performs authentication with the portable storage through the interface module;
a session key generation module which generates a session key shared with the portable storage; and
a digital rights management (DRM) agent which transfers the rights object converted into in the converted format by the rights object converter module to the portable storage through the interface module.

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.
