Key cache management through multiple localities
Charles Ball,Ryan Charles Catherman,James Patrick Hoff,James Peter Ward +3 more
- 22 Dec 2003
TL;DR: In this article, a method for a plurality of key cache managers for plurality of localities to share cryptographic key storage resources of a security chip, includes: loading an application key into the key storage; and saving a restoration data for the application key by a key cache manager, where the restoration data can be used by the key cache Manager to reload the application Key into the Key Storage if the applicationKey is evicted from the Key storage by another Key cache Manager.
