keymaster_key_characteristics_t Struct Reference
#include <
keymaster_defs.h
>
Parameters that define a key's characteristics, including authorized modes of usage and access control restrictions. The parameters are divided into two categories, those that are enforced by secure hardware, and those that are not. For a software-only keymaster implementation the enforced array must NULL. Hardware implementations must enforce everything in the enforced array.
