TRANSPARENT AWARE DATA TRANSFORMATION AT FILE SYSTEM LEVEL

摘要

A mechanism for enabling efficient encryption and integrity validation of network files. When a request to read a file stored in a local network file system is received, the local network file system examines cryptographic attributes associated with the file to determine if the file is encrypted or integrity- verified. If the cryptographic attributes indicate the file is encrypted, the local network file system omits the encryption of the file by the local network file system prior to passing the file to the remote network file system. If the cryptographic attributes indicate the file is integrity- verified, the local network file system omits the integrity- verification of the file by the local network file system prior to passing the file to the remote network file system. The local network file system then transmits the file to the remote network file system.
