Method of constructing domain based on public key and implementing the domain through universal plug and play (UPnP) |
摘要 |
<p>A method of constructing a unique domain for preventing content from being illegally used by an unauthorized third person in a public key-based architecture and applying the constructed domain to a home network using universal plug and play (UpnP). The method of the present invention includes selecting one of controlled devices that are operable as a master device and determining the selected device as the master device; performing device authentication in such a manner that other controlled devices receive a secret information block from the determined master device and create certificates; and determining slave devices by selecting one or more devices among the authenticated controlled devices.
