In this paper, we propose a user management system for networked consumer electronics (nCE). The proposed system extends Tokunaga's hybrid P2P system in such a way that the inquiries concerned with client peers submitted by service-provider peers are handled by several authentication proxies instead of a centralized management peer, although client peers still have to register themselves to the centralized server. A prototype of the proposed system is implemented using JXTA framework, and is evaluated via experiments. The result of experiments indicates that the proposed system certainly reduces both the load of the centralized server and the time required for the authentication process.
