CTS Test for Secure Element

To provide better security, some devices have an embedded Secure Element (SE), which is dedicated, separate tamper-resistant hardware to store cryptographic data. Open Mobile API is a standard API{: .external} used to communicate with a device's Secure Element. Android {{ androidPVersionNumber }} introduces support for this API and provides a backend implementation including Secure Element Service and SE HAL.

Secure Element Service checks support for Global platform-supported Secure Elements (essentially checks if devices have SE HAL implementation and if yes, how many). This is used as the basis to test the API and the underlying Secure Element implementation.

Open Mobile API test cases

Open Mobile API (OMAPI) test cases are used to enforce API guidelines and to confirm the underlying implementation of Secure Elements meets the Open Mobile API specification. These test cases require installation of a special applet, a Java Card application on Secure Element, that is used by the CTS application for communication. For installation, use the sample applet found in google-cardlet.cap{: .external}.

To pass OMAPI test cases, the underlying Secure Element Service and the SE should be capable of the following:

Access Control test cases

Access Control uses configured in the Secure Element ensure that only the application with access to an applet can communicate with it. Additionally, Android supports configuring rules for specific APDUs that can be exchanged by the APK.

To pass these tests, configure special Access Control Rules, either Access Rule Application Master (ARA) or Access Rule File (ARF). You should use the applet that is used for OMAPI tests as the same commands need to be supported to pass the Access Control tests.

Create an instance of the applet under these AIDs:
