Abstract: Ein Verfahren beinhaltet Empfangen einer Anforderung zum Speichern einer ersten Datei als unveränderliche Datei. Das Verfahren beinhaltet auch Suchen nach einer zweiten Datei, die gespeichert und in Bezug auf die erste Datei redundant ist. Ferner beinhaltet das Verfahren Ermitteln, ob die zweite Datei veränderlich oder unveränderlich ist. Das Verfahren beinhaltet Speichern der ersten Datei als Masterkopie, wenn die zweite Datei veränderlich ist, und Ersetzen der zweiten Datei durch einen bedingten Link, der auf die Masterkopie verweist. Das Verfahren beinhaltet Ermitteln, welche Datei der ersten und zweiten Datei einen späteren Ablauftermin und einen früheren Ablauftermin aufweist, wenn die zweite Datei unveränderlich ist, Speichern der einen Datei mit dem früheren Ablauftermin der ersten und zweiten Datei als Masterkopie und Ersetzen der einen Datei mit dem früheren Ablauftermin der ersten und zweiten Datei durch einen bedingten Link, der auf die Masterkopie verweist.

Abstract: A file server receives a request from a client to mount an encrypted file system. The file server informs the client that the requested file system is encrypted and, in turn, receives a session ticket from the client that includes a security protocol mounting selection. The file server decrypts the client's user's encrypted private key, and then decrypts the requested encrypted file system using the private key. In turn, the file server sends the decrypted file system to the client over a secure channel, which is based upon the security protocol mounting selection. In one embodiment, a key distribution center server receives a request from the client for the client's user to access the encrypted file system at the file server. The key distribution center server retrieves an intermediate key; includes the intermediate key in a session ticket; and sends the session ticket to the client.
