Abstract
A network storage device is disclosed for use in a secure array of such devices to support a distributed file system. Each device is an independent repository of remotely encrypted data objects to be accessed by authorized network clients. All encryption is done by the clients, rather than by the devices. In order for the system to revoke access to an object on the device, the object must be re-encrypted. Each storage device has a device owner for controlling access to the device's data. All data requests from the clients and responses to them are authenticated using keys derived from the owner key and hashed message authentication codes.
