摘要

在本文中，我們探討如何建立一個適用於無線網路的安全通道。我們利用了Diffie-Hellman交談金鑰交換協定配合Interlock Protocol建構起這一項通道；透過WAP瀏覽器API呼叫底層加、解密程式（我們採用Rijndael），達成安全傳輸。而這項設計可以確保使用者與伺服器之間能夠做到安全的溝通，使得使用者與伺服器彼此傳遞的資訊不致外漏，讓有心之人有機可乘。我們並將所提方法實作於無線網路環境中。

In this paper, we study the problem of how to build a secure communication channel in wireless environment. We apply the Diffie-Hellman key exchange agreement and the Interlock Protocol to construct secure channels. From WAP browser, the API calls for encryption and decryption modules (Rijndael algorithm) to fulfill the security requirement. By using the proposed method, a client user and the server can transmit data securely via an insecure path. We also implement the proposed scheme in a wireless environment, which is getting much more attention.
