"cybertage"
by Vladimir Z. Nuri 17 Dec '03

17 Dec '03

how about a new term for all the various enemies of cyberspatial advancement? the censors, the luddites, the spooks, the politicians, the demagogues, the rabid media (all of which there seems to be no shortage of lately): "cyberteurs" engaging in "cybertage" now if we can only get a strong stigma associated with the words and label all the enemies with it. I think it could really stick. a sort of reaction by cyberspatial citizens against all the encroachments and disrespect.

Cellular Telephone Experimenter's Kit (2600 article)
by Michael Handler 17 Dec '03

17 Dec '03

[ Apologies about posting to the list, but my mail directory got scragged by Net Access admins, and I lost the list of people who wanted this. Interesting stuff regardless.] ----- BEGIN ARTICLE ----- >From _2600_ Magazine, Spring 1994 (Volume 11, Number 1), pp 20-21 ***** Product Review ***** Cellular Telephone Experimenters Kit $125, Available for OKI 900 Network Wizards PO Box 343 Menlo Park, CA 94026 Voice: (415) 326-2060 Fax: (415) 326-4672 Email: info(a)nw.com OKI Telecom (404) 955-9800 (800) 554-3112 Review by Mr. Upsetter Any technology that combines radio, telephones, and computers is sure to interest hackers. It's no wonder cellular telephony has received so much attention. Now exploring the system is a little easier for us. A company called Network Wizards has introduced an interface that allows control of an OKI 900 cellular telephone from a DOS PC via the RS-232 port. Their Cellular Telephone Experimenters Kit (CTEK) consists of an interface, four DOS executables for controlling the phone, and a C function library so you can write your own programs. Also included on disk are a user's manual, function library, and a short cellular tutorial. The interface itself is contained in a small black box with a DB25 connector on one end. A cable with a specialized plug for connecting to the OKI is on the other end. Inside is a PIC16C54 microcontroller which converts data from the OKI to standard RS-232 data. The interface also has a mini stereo jack for connecting a microphone and earphone. The DOS executables included with the CTEK allow you to perform numerous functions. The MENU.EXE program allows you to change any of the phone's five NAMs. (A NAM, or Number Assignment Module, consists of a telephone number, system ID, initial paging channel, access overload class, and group ID mark. This information, along with your ESN, identifies your phone in the cellular system.) This program also allows you to read, write, and edit the phone's 200 alphanumeric memories. The TEST.EXE program, allows you to manually control the transmit and audio functions of the phone. You can turn the transmitted on or off and set the channel, SAT, and transmit power. You can also set the volume, mute the transmit, or recieve audio as well as set the audio source to the earpiece, sounder, or external jack on the CTEK interface. The TEL.EXE program allows you to monitor the paging channel and displays all the forward control channel messages. It also allows you to place and receive a phone call while displaying the voice channel messages. The KEYCON.EXE program simply allows you to press keys on the OKI from the computer keyboard. The programs provided with the CTEK certainly expand on the functionality of the phone. But to do the really fun stuff, you need to write your own programs. Source code to TEL.EXE and KEYCON.EXE are provided to get your started with the CTEK function library. Although my C programming skills were a little rusty, I found it easy enough to write programs with the library. I wrote a cellular scanning program which had the following capabilities: * Scan for a paging channel and display the messages. If a voice channel is assigned, go to that channel and listen to the call. * Scan voice channels and listen to active channels. * Scan OMNICELL channels and listen to active channels. * While listening to a call, display the voice channel messages. * Automatically follow handoffs. * Decode DTMF, change the volume or audio source. * Automatically mute the audio and stop monitoring when the call is released. Other functions in the library allow you to send reverse channel messages, get the received signal strength, control transmitter and audio functions, and read the phone's memory. Overall the function library is quite versatile. I had several other ideas for programs, for instance: * Log all messages and call information for certain cellular phone numbers. You could log paging channel messages, calls placed and received, call durations, DMTF digits dialed, cell channels used, etc. * Create a "spectrum" display of the cellular band by scanning all channels and recording the signal strength. * With a map of cell cites in your area, physically track a phone as it moves from cell to cell. I had great fun exploring the cellular network while playing with the CTEK. But this kit isn't for everyone. To get the most out of CTEK, you need to write your own programs. The executables provided in the kit really don't use the phone to its highest potential. Also, the OKI 900 isn't the cheapest phone in the world. It goes for about $400 to $450 new, perhaps $300 used if you can find one. Still, you could put together a great cellular monitoring system comparable to the ones designed for law enforcement for a few hundred dollars as opposed to a few thousand dollars. The CTEK is best suited for monitoring the cellular network rather than as a tool for fraud. You cannot change the phone's ESN with the CTEK. In fact, the library function which lets you send reverse control messages won't even let you send a bogus ESN. Overall, the CTEK is a well-designed product, both in hardward and in software. While it's currently only available for the OKI 900, Network Wizards promises a version for the OKI 1150 soon. ***** Sample output of my cellular monitoring program ***** (phone numbers have been masked) Monitor system A or B?

Need Suggestions for Random Numbers
by jpinson＠fcdarwin.org.ec 17 Dec '03

17 Dec '03

Greetings from the Galapagos islands! I am working on a PC implementation of a one-time pad cipher, and am trying to develop a way to produce an "acceptable" random file to be xor'd with the plaintext. I have seen here and elsewhere descriptions of hardware random number generators (Geiger counters measuring random nuclear decay, microphones picking up background hiss etc.), but I need something that can be implemented entirely in software. I recognize that there is probably no "perfect" software solution, but some techniques are better that others. (i.e.: I want to avoid making a REALLY stupid mistake here!) Listed below are a few ideas I have come up with, but I need some feedback from more knowledgeable sources. Any suggestions or comments would be greatly appreciated. If you reply to me directly, I will summarize for the list. Please don't suggest book/journal references that are not accessible via the internet. It would take me about 6 months to order books from here. (Everything I know about the outside world arrives via my Pegasus/KA9Q mailer :-) Also, can anyone recommend a statistical test for randomness, or for detecting repeating patterns in a "random" file? (I remember some years back someone demonstrated the Apple II random number generator was flawed by converting the random numbers to screen coordinates and "painting" the screen. No matter how long you ran the program, certain areas of the screen were never filled in. In other words, certain numbers were never generated.) Thanks in advance for any assistance. Jim Pinson Galapagos Islands, Ecuador. jpinson(a)fcdarwin.org.ec PGP public key available by finger ----------Possible methods------------ (note: using the Borland C++ compiler) - Generate a random file using Borland's random number generator, then run the output through an encryptor (PGP, DES etc.). Possible variation: running through several different encryptors or multiple passes through a single encryptor. - Generate two random files using different random number generators, then xor'ing the two files together to produce the final file. - Generate a "bunch" of small random number files, reseeding the generator before each run. The resulting files would then be concatenated to produce the final file. (my thought here is to keep the random files small enough to avoid the eventual repeat of sequences that I understand occur in random number generators). - Combinations of the above? - Other: Suggestions welcome. -------------end------------- On the subject of using audio input for generating random numbers: has any one tried using an audio file created by the Windows sound recorder program? What would be a good source of random meaningless sound? (an quiet room, ocean surf, repeats of Gilligan's Island, old presidential speeches (pick your favorite president). :-)

I found this address for it after a couple of tries getting to the "Diehard.html" site. I couldn't connect to that. This FTP site works though. I found it at http://ourworld.compuserve.com/homepages/bob_jenkins/testsfor.htm To qoute, "An excellent test of random sequences is DIEHARD, maintained by George Marsaglia. You get it by ftp from stat.fsu.edu, login anonymous, cd pub, cd diehard, then get what you want. NOTE: George needs you to send him mail at geo(a)stat.fsu.edu when you download it so he can keep getting grants to support his excellent work." Aaron.

Multi-drop quantum cryptography article in Nature 385, 47-49 (1997)
by Paul Pomes 17 Dec '03

17 Dec '03

(Reproduced from <http://www.nature.com>) Eavesdropping on the line Secure electronic communication is becoming increasingly important. In recent years, quantum cryptography has been investigated as a means of detecting eavesdroppers on private lines. When quantum mechanical processes are used to establish the 'key' used for encryption and decryption, any eavesdropping during transmission leads to an unavoidable and detectable disturbance in the received key information. This technique has been demonstrated to be effective on standard communication lines between two users, but Paul D. Townsend now introduces a practical scheme for a multi-user network. This work demonstrates the technical feasibility of quantum cryptography for practical applications.
