Android communicates with Nugget apps in order to implement security related HALs. Currently, those HALs are Keymaster, Weaver and OemLock.
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.
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 ofcall_application()
- Generated services
This directory contains the components to support Citadel connected to Android.
