C'punks, Okay, somebody needs to fess up. I *know* someone on the Cypherpunks Channel is writing about the Clipper Chip and other crypto-privacy issues for /Expat World/. I thought I was the only one who had even heard of this newsletter for expatriates until I saw some of the crypto articles. Whoever it is, is doing a great job. In the June 15 issue, in the article, "How Big Brother Wants to LIsten, Too," the writer coined the term "Al Gorewellian." Gotta love it. If the writer of these articles is reading this note, please let us know who you are. You deserve the recognition. (If you want to keep a low profile, how 'bout sending me private e-mail? I'd like to discuss some things with you.)

Real truth about Cell phone tracking
by rusty＠hodge.com 17 Dec '03

17 Dec '03

1. Cellular phones "register" (the proper term) themselves whenever they move into a new cell (the coverage area provided by a base or tower - not the proper term. They do this by scanning the control channels when the current one falls below a certian signal strength. If you have cellular monitoring equipment, you will see the registration confirmations transmitted on the control channel, complete with the MIN (mobile identification number, or cellular phone number). The MTSO (mobile telephone switching office) knows what MINs are registered in each cell at a given time. 1a. A cellular phone can be "tracked" if it is turned on. It does not have to be in use. 2. If you are in a fixed position, and your phone is going between service and no service modes, you are at the edge of coverage area, and some of the time the control channel is falling below the scan threshold. It then tries to register with another cell and another until it is successful. It is scanning control channels when the no service lite is on. 3. There is a test mode defined in the NAMPS standard that causes a phone to begin transmitting on a designated frequency. And since the mouthpiece on a cellular phone is not switched off when the phone is on hook, you can easily bug someone's car this way. 4. Many of the cellular-based vehicle tracking systems only use the cellular phone to transmit data back to company headquarters, and do not determine location via triangulation or doppler direction finding techniques. These are not reliable enough for moving targets due to all the RF reflections. Also, my (limited) experience with doppler-based triangulation DFing shows how hard it is to DF a modulated FM signal. And since all cellular phones are transmitting a SAT tone (a 6kHz-ish supervisory audio tone) all the time, I think this would be very hard to do. 5. In major metro areas, individual cells cover extremely small areas... often every mile or two on the freeway, you will see another cell site. So you know exactly where to send a helicopter to. 6. For under $1000, you can buy a box which hooks up to a PC and controls a scanner and decodes the cellular control channels (and reverse channel data too). This includes software for following cellular calls as they hop from cell to cell, paging requests (get a phones attention), and displaying the MINs that register in a given cell (or cells, but you need one receiver for each cell you are monitoring!). 7. From the moment your phone starts ringing, there is an audio path back to the MTSO. When your phone is ringing, it has been assigned a channel and is transmitting. Pressing the send button to answer the phone sends a signal to the MTSO telling the switch to connect the landline to the channel the phone is on. This is especially evident on Ericcison switches (like LA Cellular uses). -- Rusty Hodge <rusty(a)hodge.com>

If you've had the ability to listen to any voice or e-mail traffic you felt like with a simple telco set or inexpensive computer any time, anywhere you felt like, wouldn't you put up a fight? It's like trying to take a gun from a NRA member. Once you have a freedom to do something you aren't going to give up easy. It's only going to be more difficult since NSA, and other three letter orgs are part of the government. Our metro-police, FBI, CIA, XXX, have been able to tap phone and e-mail (illegally or with court permission, or in the name of "national security") as easy as plugging in a toaster. Once citizens start using crypto systems, these three letter orgs are going to have to work for a living. OK, so a crook is using crypto in his communications. Most are so stupid, getting the keys won't be that hard and even better... the crook will still think his comm link is secure. I'll stop here with my arguments for dropping the barriers to crypto. For NSA, finding the right string to pull is probably real easy. The only thing we can do is continue to apply pressure at all fronts. Educating the general public is on one front. EFF has other fronts. ... __o .. -\<, chris.claborne(a)sandiegoca.ncr.com ...(*)/(*).

Re: Keep Out--The Journal of Electronic Privacy
by John.Schofield＠f903.n102.z1.fidonet.org 17 Dec '03

17 Dec '03

rr> About "Keep Out": you might want to be more precise in your blurbs. As rr> things stand, I'm leery of trusting anything I might see in rr> your journal. rr> RSA is not broken, as far as I know. If you have verifiable details that rr> it has, that'll be quite a scoop. If you meant to say "the _factoring_ of rr> RSA-129," well, you should have said that instead. My apologies to the net. RSA is certainly not broken, and I was aware of that when this press release was written. My word choice was sloppy. In the article, the information comes from people I have interviewed who have direct, first-hand knowledge of the effort--people like Arjen Lenstra, who wrote the software that made the factoring possible. rr> > * An interview with Phil Zimmermann, including his thoughts on rr> privacy in the digital age, export controls on cryptography, the rr> copyright on RSA (the algorithm used in PGP), and information on his rr> struggle with US Customs over exporting PGP rr> A publisher, of all people, really needs to understand what a copyright rr> is. Note that we cannot copyright ideas, only our expression of those rr> ideas. Referring to a copyright on "the algorithm used in PGP" is rr> nonsense. Instead, PKP holds licensing rights to a system _patent_ on rr> using RSA to perform public key encryption. Again, I used sloppy language. And again, my apologies. This is certainly not the last mistake I will make. There will be errors in Keep Out. However, I will do my damndest to make sure Keep Out remains as accurate and unbiased as it can be. And when I make mistakes, I trust Cypherpunks to let me know about them, so I don't repeat the mistakes. It's a damn sure bet I won't be making these two errors again! --John Schofield -- : John Schofield - via mcws.fidonet.org - Public Access (213)256-8371 : ARPA/INTERNET: John.Schofield(a)f903.n102.z1.fidonet.org : UUCP: ...!cheshire!mcws!903!John.Schofield : Compu$erve: >internet:John.Schofield@f903.n102.z1.fidonet.org
