Abstract

With a home network, a device can dynamically join a home network obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. Devices can subsequently communicate with each other directly. Device discovery protocol defines how network services can be discovered on the network. In this paper, we propose the secure discovery method of devices that uses mutual authentication with symmetric key between devices. This method that we present distributes symmetric-key to home network devices by the home server. Using this key, mutual authentication is performed between home appliances. It enables any appliance under any middleware's control to securely communicate any other appliances.

홈 네트워크 환경에서 디바이스는 동적으로 네트워크에 연결되고, IP 주소를 얻고, 자신의 기능을 알리고, 다른 디바이스의 존재 및 기능을 파악할 수 있다. 이런 과정 이후 디바이스는 서로 직접 통신을 할 수 있다. 본 논문에서는 디바이스들 사이에 대칭키를 이용하여 상호인증을 수행하는 디바이스의 안전한 검색방법을 제안하고자 한다. 이 방법은 홈서버를 사용하여 홈 네트워크 디바이스들에게 대칭키를 분배한다. 이 키를 사용하여 홈 디바이스들 사이의 상호인증이 수행되어 진다. 이 것은 미들웨어의 제어하에 두 디바이스가 안전하게 통신할 수 있는 기능을 제공한다.
