Smart environment authentication: Multi-domain authentication, authorization, security policy for pervasive network

As a number of home network services are available and smart environment is expanding into ubiquitous computing environment, we need to protect smart environment system from illegal accesses and a variety of threats. Smart environment is exposed to various cyber attacks of Internet, involves hacking, malicious codes, worms, viruses, DoS attacks, and eavesdropping since it is connected to Internet. So in this paper, we propose authentication in a smart environment security for guaranteeing reliability and availability including authentication, authorization and security policy system. Furthermore, we describes smart environment authentication which is the basic and essential element in the pervasive network security. And our device authentication concept can offer pervasive network service users convenience and security.
