用于定义密钥特性的参数,包括已获授权的使用模式和访问权限限制。这些参数分为两类:由安全硬件强制执行的参数和不由安全硬件强制执行的参数。对于仅软件的 Keymaster 实现,强制使用的数组必须为 NULL。硬件实现必须强制执行强制执行数组中的所有内容。

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.\n\n\nDefinition at line\n[310](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\nof file\n[keymaster_defs.h](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\n.\n\nField Documentation\n-------------------\n\n\n|---------------------------------------------------------------------------------------------|\n| [keymaster_key_param_set_t](/reference/hal/structkeymaster__key__param__set__t) hw_enforced |\n\n\nDefinition at line\n[311](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\nof file\n[keymaster_defs.h](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\n.\n\n|---------------------------------------------------------------------------------------------|\n| [keymaster_key_param_set_t](/reference/hal/structkeymaster__key__param__set__t) sw_enforced |\n\n\nDefinition at line\n[312](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\nof file\n[keymaster_defs.h](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)\n.\n\n*** ** * ** ***\n\nThe documentation for this struct was generated from the following file:\n\n- hardware/libhardware/include/hardware/ [keymaster_defs.h](https://android.googlesource.com/platform/hardware/libhardware/+/master/include/hardware/keymaster_defs.h)"]]
