基於RFID的點對點VoIP語音通訊系統

Peer-to-Peer VoIP System Based on RFID

指導教授 : 柯志鴻

摘要


由於網際網路的普及與較低的電信費率,人們逐漸使用網際網路進行更便利且更即時的連絡。即時通訊和網路語音通訊兩個最具代表性,其中MSN和SkyPE已成為人們最普遍使用的工具。然而,這些軟體並非絕對安全,例如,沒有嚴謹的加密或根本沒有加密,因此衍生出隱私與安全問題。所以,如何確保使用者能安全地使用軟體進行通話或傳訊,而且不會被第三者竊取,便是一個重要議題。本研究採用微軟.Net平台和P2P網路技術,以及AES與RSA演算法,實作一個安全且效率高的VoIP通訊系統。而且,我們使用Mifare Card去儲存聯絡人和金鑰等各種資訊,以便增加隨身攜帶的便利性。

Due to the popularity of the network and the lower rates of telecommunications, people gradually contact with each other via the internet in a more convenient and more immediate way. The two most representatives are the IM and VoIP, and MSN (IM-type) and Skype (VOIP-type) have become popular communication tools. However, these tools are not absolutely safe, for example, there is no strict encryption or no encryption at all, and thus they cause a lot of issues of privacy and security. So, how to guarantee that users can safely use the software for calling or messaging and would not be intercepted by others is an important issue. In this study, we use Microsoft .Net platform and P2P technology, as well as AES and RSA algorithms, to implement a safe and efficient VoIP communication system. Moreover, we use the Mifare Card to store the information of contacts and security key in order to increase the convenience of carrying.
