  • Method and apparatus for device state based encryption key
    Patent number: 9891969
    Abstract: An apparatus and a method for encrypting and decrypting data in a device are provided. The apparatus includes a processor and a memory. The processor is configured to transmit a data command from an application to an encryption driver that executes in a kernel space, determine if the application is authenticated to perform the data command based on an access policy, transmit, when the application is authenticated, a first key to a cryptographic library that executes in an application space, and perform the data command based on the first key after receiving a response via the cryptographic library. The first key is stored in an encryption driver in the kernel space and is not available to applications in the application space.
