Abstract
Secure key derivation within a virtualized execution environment may involve a key derivation module executing within a platform layer of the execution environment. An application executing within an application layer of the execution environment may access the key derivation module in order to generate a cryptographic key according to a key derivation function. Instead of being returned to the application, the derived key may be stored within a secure storage area of the execution environment without being stored, even temporarily in the application layer, or other non-secure areas, of the execution environment. The application may receive a reference to the derived key usable by other cryptographic processes. The application may pass the key reference to a method of a cryptographic module and the cryptographic module may use the key reference to access the derived key from the secure storage for use in performing any of various cryptographic processes.
