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.

Abstract: A method for a plurality of key cache managers for a 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 application key is evicted from the key storage by another key cache manager. The method allows each of a plurality of key cache managers to recognize that is key had been removed from the security chip and to restore its key. The method also allows each key cache manager to evict or destroy any key currently loaded on the security chip without affecting the functionality of other localities.

- 07 Mar 1994
TL;DR: In this article, a cache manager for file system data, status and path name information is proposed, where file system requests are satisfied by the cache if possible and passed to a remote file system for servicing if necessary and modification logs are created when the client is disconnected by logging objects that optimize the log as it is created.
