Abstract:
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for encryption and key management. The method includes encrypting each file on a computing device with a unique file encryption key, encrypting each unique file encryption key with a corresponding class encryption key, and encrypting each class encryption key with an additional encryption key. Further disclosed are systems, methods, and non-transitory computer-readable storage media for encrypting a credential key chain. The method includes encrypting each credential on a computing device with a unique credential encryption key, encrypting each unique credential encryption key with a corresponding credential class encryption key, and encrypting each class encryption key with an additional encryption key. Additionally, a method of generating a cryptographic key based on a user-entered password and a device-specific identifier secret utilizing an encryption algorithm is disclosed.

Claim (Index 8):
At least one non-transitory computer readable storage medium configured to store instructions that, when executed by a processor included in a computing device, cause the computing device to encrypt content, by carrying out steps that include:\n receiving a user passcode; combining at least part of the user passcode with at least part of a unique identifier associated with the computing device to produce a combined value, wherein the unique identifier is directly accessible only to a hardware module within the computing device, and is stored by the hardware module in a manner that prevents software executing by way of the processor from directly accessing the unique identifier; carrying out an iterative function on the combined value to produce a derived key, wherein the iterative function is based on at least one performance parameter associated with the computing device; and encrypting content on the computing device with the derived key.
