Abstract
A system to manage and control usage rights for cryptographic keys. A kernel process is provided with secure and exclusive authorization to access certain keys in a key hierarchy. Special authorization is required for other processes or users to access keys used by the kernel. A persistent storage area is used to hold a Kernel Authorization Data field for the root key and/or other keys used by the kernel or other specialized processes. The authorization data, and the keys it protects, can be used to protect other portions of, or the entire, key structure. The persistent storage area is reserved in a TPM or similar security hardware.
