A method and apparatus for effectively managing a plurality of licenses are provided. The method includes selecting a value, which corresponds to license information, from a Hash mapping table; selecting a node corresponding to the license information from a tree structure corresponding to the value; and searching for a license by using license location information contained in the node. The apparatus includes a Hash function processor which computes a first value corresponding to the license information using a Hash function; a controller which selects a tree structure corresponding to the license information based on the first value computed by the Hash function processor; a tree structure manager which selects a node corresponding to the license information from the tree structure; and a storage unit which stores the license.

摘要:
A home network system allowing a user to directly control joining or removing of member devices in a domain using a user interface and to effectively control a status change of the member devices of the domain and a management method therefor. The home network system includes: a master device, which forms a domain with more than one controlled device, transmits a predetermined domain key to the controlled devices included in the domain, generates a new domain key whenever a configuration of the domain is changed, and transmits the new domain key to the controlled devices remaining in the domain; and a control point, which provides a user interface allowing a user to directly change the configuration of the domain.

Disclosed is a domain authentication method for exchanging content between devices. The domain authentication method for exchanging content between devices according to the present invention includes a first step of setting domain identification information into a predetermined device connected on a wired/wireless network; a second step of generating a domain secret key using the set domain identification information and predetermined device identification information; a third step of generating a predetermined first code value and transmitting a first packet encrypted with the first code value using the domain secret key generated in the second step; a fourth step of receiving a second packet that is encrypted with the first code value and a second code value; and a fifth step of decrypting the second packet received in the fourth step.
摘要:
A method of providing a Social Networking Service (SNS) group inviting service via an SNS server, the method including receiving an SNS group invitation request containing second-user identification information, from a first device of a first user, generating first authentication information corresponding to the second-user identification information in response to the SNS group invitation request, receiving an SNS group joining request containing second authentication information, from a second device of a second user, and comparing the first authentication information and the second authentication information with each other and permitting the second device to join the SNS group.
摘要:
A method of managing a home network key in a home network environment, which has a key management server for managing the home network key and a plurality of home network devices, includes: allowing a home network device to generate device unique information and to transmit the device unique information to the key management server; allowing the key management server to generate a parameter for generating the home network key by using the device unique information and to transmit the parameter to the home network device; and allowing the home network device to generate the home network key by using the parameter. The generated home network key being independent of the device unique information.
摘要:
A method and apparatus for performing authentication are provided. The method includes: receiving an authentication request signal for requesting authentication from an external device; determining whether authentication has been performed with the external device that has transmitted the authentication request signal; based on the determination, selectively outputting an indication representing that it is necessary to perform authentication with the external device; if the indication representing that it is necessary to perform authentication with the external device is output, receiving an authentication execution command for instructing the execution of authentication in response to the indication; and performing authentication with the external device according to the authentication execution command.
