Beech Trees,

     The identity of the organization is not secret, but neither is it to be bandied about.  There are a number of foreign intelligence services which wish to keep abreast of which test formats are used by specific U.S. agencies.  The less they know, the harder it is for them to penetrate those agencies.

George,

     You ask why a technique with forensic applications should be kept out of the public domain.  I would argue that one reason for doing so is because it is also used for security purposes.  Let me give you an analogy.  Intrusion detection systems are unclassified, off-the-shelf items.  Yet it is a prudent practice for any homeowner, corporation, or government agency to withhold information about which specific alarm systems and devices they are using to safeguard their possessions.  This greatly increases the difficulty of trying to penetrate the defenses to access that which must be protected.

Peace,

Gordon
