1 GSRA DLNA DLNA(Digital Living Network Alliance), DLNA,, DLNA,, GSRA(Group-based Secure Remote Access) DLNA,, Proposal of Remote DLNA ommunication System for GSRA NAKI HTTA As a guideline DLNA (Digital Living Network Alliance) since it was formulated, DLNA has started to spread information appliances compliant users in home networks, video and photos, can now be made to share content such as music or. DLNA But there is a problem of not being able to use equipment must be present between the same home network. Therefore, the scheme has been proposed that make sharing content as before and go in the visited network. In this paper, these problems GSRA (Group-based Secure Remote Access) into the basic features DLNA proposes a method for connecting with each other in spite of being outside the home network by combining communication. In the proposed scheme for DLNA devices to enable the use of all existing equipment as well as a home network so that communications can be started simply by changing the home gateway of the home. 1.
