A Study on Secure Contents Transmission in Home Domain

Home network is where all the electronic appliance in the house are gathered to form a united network. It is being expanded due to the fact that the electronic appliances are developing through the time. The increasing number of digital contents are also helping. However, because the mutual management among contents electronic appliances are weak, it is hard to constantly maintain the protection of digital contents´ copyrights and if moving contents among electronic appliances are needed, license from DRM server needs to be reissued. Therefore in this thesis I will introduce the framework that will allow contents to move freely to other device through device mutual authentication in home network as well as suggest the system that will reduce the pressure of maintaining DRM server license and make user authentication allow access to contents even when an outside user tries to access home network.
