Keyguard-bound keys to limit Key usage and protect sensitive messages, Secure Key Import, and keyguard-bound keys have been added to the latest Pie version of Android’s mobile operating system. Make the security key easy to use, but at the same time protect the key in the application and operating system. The Android Keystore provides application developers with encryption tools to protect user data. Keystore moves the Cryptographic Primitives that can be used in the software function library from the Android OS to the secure hardware, so that the keys can only be used in the secure hardware, and the keys are protected in a more rigorous way to ensure that the application secrets are not subject to various forms of attack. The Keystore provides when and how the application formulates the key.
