Abstract

A method of establishing a home domain capable of reproducing multimedia content, and a smart card (500) therefor. The method includes creating (S4) a domain certificate (140) for a reproducing device (100) by inserting the smart card into the reproducing device, creating a session key by inserting the smart card into a home server (200), and verifying the domain certificate of the reproducing device and transmitting the created session key to the reproducing device if the device is a legitimate device. Alternatively, the method includes using an external certificate authority (300) to determine whether the reproducing device is a legitimate device. The smart card includes a certificate-creating module (570) for creating a domain certificate for a reproducing device when the smart card is inserted into the reproducing device, a session key-creating module (560) for creating a session key when the smart card is inserted into the home server, and a certificate-verifying module (580) for verifying the domain certificate of the reproducing device before transmission of the created session key to the reproducing device.

Description

technical field [0001] The present invention relates to a method for establishing a home domain (home domain) capable of reproducing multimedia content and a smart card used for the method, in particular to a method for establishing a home domain and a smart card for the method, wherein in order to securely receive and Digital data including multimedia content provided from the outside is reproduced, and devices constituting a home network are authenticated using smart cards.
