这些键集通过它们的键，提供了对保护数据的读写权限。

These keysets provide read and write access to the data protected by their keys.

要使得一个内核扩展成为键保护的内核扩展，您还必须定义它的私有或者半私有数据，以及它如何使用键来保护这些数据。

To make a kernel extension key-protected, you must also define its private or semi-private data and how it USES keys to protect that data.
