KEY CACHE MANAGEMENT THROUGH MULTIPLE LOCALITIES

摘要

PROBLEM TO BE SOLVED: To provide a method for a plurality of key cache managers for a plurality of localities to share cryptographic key storage resources of a security chip.

SOLUTION: This method includes: a step for loading an application key into a key storage; and a step for saving restoration data for the application key by a key cache manager. The key cache manager can use restoration data to reload the application key into the key storage if the application key is evicted from the key storage by another key cache manager.
