電子商務的蓬勃發展，加上行動裝置的盛行，改變了消費者購物的習慣，也帶起了行動支付的成長空間，然而如何提供一個便利的交易環境，還要兼顧安全性，保障消費者的個人資料和交易明細，讓消費者在手機看到喜愛的商品可以安心、迅速的完成購買，是每個商家獲取行動商機所面臨的重要議題，而私有鏈的信賴機制恰好符合商家對於行動支付的要求。因此，本研究提出了一套結合私有鏈的免憑證行動支付系統，對各方面安全性進行分析，並在樹莓派上驗證其效能可行性，最終確認了其具有優良的性能。因此，我們認為本系統非常適合應用於現有之商務環境中。

The wide adoption and rapid advancement in e-commerce and the popularity of mobile devices prosper the universalness of mobile payment. However, how to provide secure, efficient and convenient mobile payment services challenges every service provider. It is important to provide a service as simple as a click to use for consumers, while on the other part, secure both consumers’ information and transactions for providers. Private chain comes to aid. The trust mechanism that built-in private chain fits the exact need of mobile payment service. In this research, we proposed a mobile payment system combining both certificateless cryptography and private blockchain. In later we discuss and analyze the proposed system in different perspectives: Security, Effectiveness, and Performance. With its outstanding records, we would like to pointed out the system is adaptive in payment applications.
