Android components for Nugget

Android communicates with Nugget apps in order to implement security related HALs. Currently, those HALs are Keymaster, Weaver and OemLock.

Services

Apps that define a protobuf service will have an app interface class autogenerated. These classes will wrap a NuggetClient. The generator can be found in the generator directory.

Asynchronous communication

Work in progress.

Currently, everything is synchronous and just exposes the call_application() function from the Nugget transport API. In future, asynchronous calls may be desired. Support for this could be added in:

  • Nugget transport API
  • NuggetClient on top of call_application()
  • Generated services

citadel

This directory contains the components to support Citadel connected to Android.
