Home Device Authentication Framework and Implementation

As home devices have various functions and have improved computing power and networking ability, home device authentication has become increasingly important for improving the security of home network users. Moreover, device authentication supplies user convenience for the home network service user because it can replace the user authentication required for the used home network service. In addition, the security of the home network can be strengthened if device authentication is considered in addition to the authentication and access control for the home network user. In this paper, we describe home device authentication framework and system, certificate profile for home devices, which is based on the Internet X.509 certificate, home device authentication mechanism, and our CA administration server. And also, we propose the tracing method of lost device using our home device authentication system.
