Besides, how much encryption is needed between two points if intercepting the traffic is expensive, the communications protocol is undocumented (as far as anyone outside NASA is concerned), and the actual frequency is also hard to find?
The appropriate question is how much encryption (and other security) is needed if interrupting the traffic causes the loss of a great deal of money and difficult (if possible at all) fixes. This is the mindset of the Fed security wienies when specifying and designing; thus it must be the mindset of the non-Fed Wienie looking to crack. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Paul H.
