本文介绍了一款名为TrustUI的应用程序，该应用在T6环境下运行，并通过将Android排除在可信计算基之外来确保安全支付过程的安全性。支付应用利用了现有Android设备驱动程序，并且整个可信计算基（包括T6）的源代码量不到10K行。

This video demonstrates the TrustUI application running in T6 (Specifically, The untrusted OS is Android while the trusted OS running in TrustZone is T6). By excluding the Android out of the Trusted Computing Base (TCB), the secure payment application reuses existing untrusted device drivers in Android safely and has a TCB (including T6) less than 10K source line of code.

When a user starts the TrustUI payment application, T6 takes over the user deivces (screen and touchpad) and waits for username and password from the user. After the users clicks the “pay” button, the app will send the payment transaction data to https:liwenhaosuper.com/trustui_demo/home/index/paythrough SSL and returns the payment transaction to Android.
