SIP控制數位監視系統之保密方式
A Secure Scheme of SIP Controlled IP Tele-Camera
摘要
本篇論文提出以SIP為通訊基礎所建構之家用數位監視系統，並針對其運用不同之傳輸協定的安全性及私密性深入探討。SIP通訊協定為現今廣為接受之VoIP網路電話技術，並可在IP網路上用來建立、修改及終結數個多媒體訊號傳呼。論文中，IP監視電話攝影機整合了數個SIP應用服務，使得其操作上更為簡易。用戶只需撥打一通VoIP電話，便可接受到自家的即時監視畫面。這樣，用戶可對其居住環境或是家人的安全更加放心。我們也詳加探討了針對SIP的網路攻擊及威脅方式，且利用現有的各種解決方案，為設計的家用數位監視系統及IP監視電話攝影機提出了一個最安全的保密方式。最後，我們也呈現了IP監視電話攝影機實驗的數據結果及結論。

This thesis proposes a secure scheme of SIP controlled IP tele-camera. We give a description about the SIP controlled surveillance IP tele-camera and analyze its security mechanism for different protocols used. The surveillance IP tele-camera can be developed by applying the latest technology within Session Initiate Protocol (SIP) domain. SIP is used for establishing, modifying, and terminating multimedia sessions over the IP network. By using some of SIP application features, the surveillance IP tele-camera can easily be integrated into everyday life. User can watch the real-time surveillance video clip by single telephone call. This will give user more secure living environment for daily basis. By analyzing different security threats against SIP and the protocols used in the application , we show how these attacks may be prevented for the proposed secure scheme of SIP controlled IP tele-camera. Finally, we present experimental results and give a brief conclusion.
