A device for managing secure communications by examining message packets to detect and control the use of encryption keys noninvasively examines an incoming message packet according to typical cryptographic protocols and sequences. If an incoming packet exhibits the use of an encryption key, such as via IKEP, IPsec, or PPTP, the device processes the packet to attempt to find the corresponding encryption key. The device compares the key to a list of known suspect keys to determine a blocked status. If the key is not on the list, a sequence of authorization rules concerning prohibited key usage attempts to determine a result. The authorization rules examine available keying attributes from the message packet, possibly via a remote server, and compute an indication concerning key usage. If the authorization rules are still undeterministic of usage of the key, the device uses a default action. The default action indicates whether to allow or block usage of the key until a deterministic response indicates the key status.

Objects contained within enormous geographically distributed virtual file servers spanning thousands (or even millions) of organizations are each assigned globally unique object identifiers, enabling the implementation of highly distributed indexing and retrieval operations. The file system API (application programming interface) is extended to provide a search capability. A search request targeting a specific domain creates a parallel namespace anchored in that domain's root directory. The parallel namespace, containing directories and links to all objects satisfying the search criteria, may be navigated using the standard file system API. Relevance scores, added as new members of the file attribute structure, enable the construction and presentation of views that convey where the centers of expertise associated with the search matter are located. In addition, a wide range of methods addressing the scalability issues associated with integrating retrieval operations into the fabric of geographically distributed virtual file servers are disclosed.

Objects contained within enormous geographically distributed virtual file servers are each assigned globally unique object identifiers. For any given global scope object identifier, the file system containing the identified object can be quickly located even when the file system is frequently unmounted from one DDS file server and mounted on another (possibly geographically remote) file server such that it is essentially a nomadic (or wandering) file system.
