So all in all its a bad idea. She’s not a spy and is not read into any ops. Especially if while you are listening, you hear a knock on the door….Interesting read, especially the part about possible coding methods. ‘Wish our female comrades a happy International Women’s Day’, that sort of thing. I’ll keep things I want to stay confidential OFF the Internet and the phone network.BrightBlueJim – So true. The agency could then make educated guesses on a submarine’s mission based on when it was and was not allowing sending of personal messages.And yes, the US Military takes this seriously, or at least it was during the Cold War. This was a long time ago.Yeah “unspecified customer” – I like that. Since around 2004, all cell phones sold in the U.S. have been required to have “enhanced” 911 location capability. You use your nifty silicon junction detector and find NOTHING! They SHOULD be protecting citizens and individuals and DON’T realize the greatest threat to the US isn’t a foreign power or individuals. Maybe we were sending to a more sophisticated class of receivers.Definitely 5-letter codes, phonetic alphabet sent SSB over a frequency somewhere in the 7-30 MHz range (based on what equipment I had in front of me – no specific recollection of the frequency).
Sure, it’s a lot easier to train a field agent to use a computer program than it is to teach them how to use a book code, but you lose the plausible deniability factor that is supposed to protect the field agent.By the way, one-time pads aren’t the best thing for field agents either, since they have to be in possession of the key!
I wonder why.When prostitutes ask John Law “Are you a cop?” they are using a tricky legal loop-hole. In such cases they often mistakenly refer to it as “breaking one-time pads”. You could use a OTP based on the page number and number of characters form the first character on the page. Bond, I see you have a book with many random five character groups. But let that be some Falafel-eaters in a cave near Lahore Pakistan chatting with a kid in Camden NJ… well that’s a different story. was that a number station?I didn’t think about it at the time, but I once operated a numbers station for a few hours, for an unspecified customer. Spammails today often include random words to fool spamfilters and sometimes garbage, i think those might be secret messages unseen by the eyes of the NSA-lineeater. Furthermore, by entering intelligently, you can boost your chances even more. Now we are surrounded by WiFi networks that can be accessed using very little energy, so something no larger than an Altoids mint can “phone home” at will. FBI) CARNIVORE system. Regarding your subject matter: NUMBERS STATIONS (NS)- Sometimes the numbers mean absolutely nothing at all. They turn on the microwave or ultrasonic dish pointing at your room and the passive cavity resonator goes to work picking up your audible conversations.Sometimes I listen and wonder if it is some poor spy out in the field just trying to order Jimmy John’s for dinner…You probably already know this, but I’ll bite anyway: Numbers stations are only useful for getting information from the big, strong organization to the small, vulnerable field agent. As fun as it is to win any prize, it's a good idea to avoid trying to win anything that you aren't excited about. Even if you never use those services, having them available can slow down your redial time. That’s not S.O.P. And yes, the pen-and-paper based one-time pad is mathematically unbreakable, both in theory and in practice, unless you make the mistake of trying to shortcut some of the pen-and-paper work by using computers (by definition totally insecure).
