ABSTRACT:
The present invention includes one or more clients in communication with a server. The client desires to send a storage construct to the server for storage. The client negotiates a transmission key with the server. The client generates a storage key associated specifically with the storage construct. The client encrypts the storage construct using the storage key and encrypts the storage key using the transmission key. The encrypted storage construct and encrypted storage key are sent to the server. The server decrypts the storage key using the transmission key. The server stores the storage construct on a storage device separate from a storage device storing the storage key. Preferably, any changes to the storage construct location, the storage key location, or the storage construct name are tracked and proper modifications are made to an association relating the location of the storage construct and the location for the corresponding storage key.
