摘要
近年來，隨著網路技術的發展與行動裝置的普及化，對於電子商務的應用越來越方便，如果使用者要進行額度較高的消費，可能使用信用卡或是電子支票做為付款方式，可是這兩種付款方式都有各自的差別，線上信用卡付費是輸入使用者的卡片資訊來進行消費，缺點是如果遇到惡意的網站就會造成資料外洩，卡片遭到盜刷，而電子支票的缺點是每使用一次電子支票必須重新申請，以及需要安全通道傳遞電子支票。 本篇論文中，我們設計一個電子支票系統，建置於行動裝置，我們在手機上建置銀行代理人，管理支票，防止支票遭到濫用，使用金鑰交換的方式，確保只有指定的收款者可以解密取得支票訊息，並且利用簽章來認證每個參與者的身份。

In recent years, with the development of Internet technology and popularity of mobile devices, e-commerce applications have been more and more convenient. If the users proceed a higher amount of spending, the payment may be made by credit cards or e-checks. However, the two methods differ from each other. Online credit card payment is processed by entering the cardholder’s information; its disadvantage is the leak of information on the malicious websites so the future unauthorized payment will occur. And the shortcomings of using e-checks are the re-application of the e-check whenever it is used, and the necessity to have a secure channel to transmit the e-checks. In the thesis, we design an e-check system built in the mobile device. We can set up bank agents in our mobile phones to manage the checks and prevent the unauthorized use of checks. By way of key agreement, it is assured that only the designated recipient can decipher the code and get the check information. And the signature is utilized to authenticate every participant''s identity.
