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.

Description

technical field [0001] The present invention relates to the field of network file systems. In particular, the present invention relates to methods and systems for secure access to encrypted file systems. Background technique [0002] Encrypting File System (EFS) is a secure file system that allows users to securely store data using symmetric and asymmetric encryption methods. An encrypted file system is typically supported on a single machine, and, in order for a user to access the encrypted file system, the user logs on to the same machine where the encrypted file system is stored. [0003] Network File System (NFS) is a distributed file system that allows users to export data from one machine (server) and import / mount data from other machines (clients). File systems themselves are generally not encrypted, although network file systems may require passwords to allow users to access a particular file system. Contents of the invention [0004] The file server receives a ...
