Internet, Countries, Nationalism, etc.
by Jim Choate 17 Dec '03

Hi, blanc has put forth an interesting assertion relating to nationalism and the Internet. If he is correct then we will have a one world government (ie technocracy) whether we like it or not. I agree with this assertion, which is why I hold that it is a waste of bandwidth trying to 'control' the Internet or access thereof by citizens of such countries as Singapore. Let them cut themselves off, it does us all a service, and themselves a dis-service. If the citizens have as much dissatisfaction as some members claim they will take care of it themselves. When they get hungry for ideas, materials, and food they will change. You can take a horse to water, you can't make him drink. You can drown him however. Then you are walking, not riding.

It would be interesting if someone could show up at Gilmore's press conferences to supply an alternative view of Gilmore himself. Of course, those still clinging to the notion that Gilmore is working for us might not be comfortable with this idea - biting the hand that feeds, etc., but I think it could be a good way to keep the moderator honest.

Watch out for the Goodtimes Virus Goodtimes will re-write your hard drive, scramble any disks that are even close to your computer, recalibrate your refrigerator's coolness setting so all your ice cream goes melty,demagnetize the strips on all your credit cards, screw up the tracking on your television and use subspace field harmonics to scratch any CD's you try to play. It will give your ex-girlfriend your new phone number. It will mix Kool-aid into your fishtank. It will drink all your beer and leave its socks out on the coffee table when there's company coming over. It will put a dead kitten in the back pocket of your good suit pants and hide your car keys when you are late for work. Goodtimes will make you fall in love with a penguin. It will give you nightmares about circus midgets. It will pour sugar in your gas tank and shave off both your eyebrows while dating your current boyfriend behind your back and billing the dinner and hotel room to your Visa card. It will seduce your grandmother. It does not matter if she is dead, such is the power of Goodtimes, it reaches out beyond the grave to sully those things we hold most dear. It moves your car randomly around parking lots so you can't find it. It will kick your dog. It will leave libidinous messages on your boss's voice mail in your voice! It is insidious and subtle. It is dangerous and terrifying to behold. It is also a rather interesting shade of mauve. Goodtimes will give you Dutch Elm disease. It will leave the toilet seat up. It will make a batch of Methamphetamine in your bathtub and then leave bacon cooking on the stove while it goes out to chase gradeschoolers with your new snowblower. These are just a few signs... Just be very careful! CI

Somehow, I thought my original post was ambiguous enough to be interpreted as support for the government's expansion of surveillance capabilities or the War on Some Drugs. Nothing could be further from the truth. I believe that the original intention of requiring cell phone providers to have the ability to triangulate all the signals they receive was so that drug dealers and other Enemies of the People could be caught easier. Since, drug dealers frequently use cell phones to avoid tracking, I thought that this was probably the primary justification. Just like the current GAK proposal, the government has found another way to justify a proposal to fool people into thinking that it's really for their own good. Many people have grown tired of hearing about the government's "compelling interest" in fighting "crime." The government claims that GAK is not only for violating people's rights by trying to get people to believe that it is a valuable service because it will allow people to recover their crypto keys if they ever lose them. In the case of the cell phone proposal, the promise of better 911 service is used to justify this latest violation of civil rights.

From: Dr.Dimitri Vulis However U.S.G. is able to say that people of Iraq or Lybia or Cuba should not be permitted on the 'net. It also bombs Iraq and murders their civilians in retaliation for something their governments supposedly did. ................................................................ The U.S.G. has many more resources than most of us to do these things, including equipment, cooperative troops, money, and recognition from other governments. If other nations disagree with the U.S.G. they have the resources to discuss, bargain, negotiate, criticize, form alliances, take their chances and retaliate, etc. These things are done on a level not accessible to the most of us. All that we individuals have are access to telephone lines, computers, and modems. Yet even as we speak the world is being "wired" with cables to further make this singular communication possible and open up avenues to non-government organized activities: international corporations are se tting up offices, services, and correspondence wherever in the world they can find markets. All this is happening even while the governments are complaining to each other about what their citizens are posting (tch, tch) and threatening to deprive each other of that privilege. While governments and their True Believer citizens are dealing with each other on one level, the rest of the world is reorganizing itself into a different order of living and doing business. They are sharing ideas and examining their concepts and beliefs, they are conducting a lot of their disagreements on the net (instead of physically against each other on the ground), opening up to a broader view of relationships between individuals, or to governments, or to religions, sexuality, etc. The situation hasn't completely changed yet, but it is in process. ..

Cellular Encryption Docs
by John Young 17 Dec '03

17 Dec '03

Thanks to David Wagner and Steve Schear, we've learned about the latest documents on cellular encryption which supercede the 1992 CAVE document, Appendix A to IS-54, which contained the CAVE algorithm. Here are the latest, followed by ordering information. TIA/EIA/IS-136.1-A -- TDMA Cellular/PCS - Radio Interface - Mobile Station - Base Station Compatibility - Digital Control Panel, October, 1996, 372 pp. $350.00. Addendum No. 1 to IS-136.1-A, November, 1996, 40 pp. Free. TIA/EIA/IS-136.2-A -- TDMA Cellular/PCS - Radio Interface - Mobile Station - Base Station Compatibility - Traffic Channels and FSK Control Channel, October, 1996, 378 pp. $310.00. TIA/EIA-627 -- 800 MHZ Cellular System, TDMA Radio Interface, Dual-Mode Mobile Station - Base Station Compatibility Standard, June, 1996, 258 pp. $120.00. These documents can be ordered from: Global Engineering Documents 15 Inverness Way East Englewood, Colorado 80112 Telephone: 1-800-854-7179 However, each of the documents lists the following related supplements which contain "sensitive information" and may be obtained by US/CA citizens from TIA by signing a Non-Disclosure Agreement and acceptance of export restrictions: Appendix A to IS-136. Appendix A to 627. Common Cryptographic Algorithms. Interface Specification for Common Cryptographic Algorithms. These controlled documents can be requested by calling Ms. Sharon Vargish at 1-703-907-7702, who will fax an NDA, and upon receipt of the completed form, will send the controlled documents at no cost. Here's the NDA: AGREEMENT ON CONTROL AND NONDISCLOSURE OF COMMON CRYPTOGRAPHIC ALGORITHMS REVISION A TO IS-54, IS-95, AND IS-136 [Note: 627 supercedes IS-54; IS-95 is for CDMA] "I, _________________________, an employee/consultant/affiliate (typed name) of __________________________, hereafter, "the company," (Company name) _____________________________ (Company address) _____________________________ and a United States or Canadian citizen, acknowledge and understand that the subject documents, to which I will have access contain information [which] is subject to export control under the International Traffic in Arms Regulations (ITAR) (Title 22, Code of Federal Regulations, Part 120-130). I also understand that the subject documents represent valuable, proprietary and confidential business information of TIA and its members.

Re: Hi again, and an invitation to kibitz

In addition to David Wagner's comments, I'd like to point out several more weaknesses. - Would Kerberos work just as well? No sense reinventing the 3-headed dog. - You're not authenticating the server to the client. - If the challenge is different every time, the server needs to keep the user's password in plaintext (unlike Unix encrypted passwords.) This means that attacks on the server's file system can steal it, and since the password is used for session encryption, it can be used to forge sessions as well. - Alternatively, if the challenge is always the same (per user), then even one eavesdrop kills you, as with Unix passwords. - Since you're using the same 7-byte password hash for the first third of the authentication as for the session key, the dictionary attack on E(challenge, First-seven-bytes) gives you the session key, so you can eavesdrop just fine. If the password is too short, you can then dictionary-attack MD4 to find it also. - There's a Diffie-Hellman variant that can do logins. Unfortunately, it's patented (by some guy from Siemens in Paderborn DE, who patented it in Germany about 2 years before I rediscovered it, and patented it in the US about 6 months before :-) It covers any login methods using commutative hashes H1(H2(x)) == H2(H1(x)). The Siemens version extends it to authenticate both ends to each other; I extended it to get a session key for encryption and/or authentication. This really shouldn't have been patentable - my rediscovery shows that it must be pretty obvious to anyone skilled in the trade :-), and rather than reinventing the wheel, I was reinventing the hubcap or tire swing.... > In article <199701140755.CAA04514(a)mail.intercon.com>, >Amanda Walker <amanda(a)intercon.com> wrote: >> (a) Server sends 8-byte challenge to client >> (b) Client sends Microsoft NT authentication response to the server >> (take the password in Unicode form, do an MD4 hash, pad with 0s to 21 >> bytes, split into 3 7-byte groups, use these as DES keys to encrypt >> the challenge three times, send the 24-byte result as the response). >> (c) If authentication fails, close the connection. >> (d) If authentication succeeds, all subsequent traffic is enccrypted with >> DES in CFB mode.

In particular, an 8 byte challenge is nowhere near enough, though the average million-dollar DES-cracker won't be as easy to adapt for 2**64 cycles of hash+DES*3 - and don't handle each third separately! At least do something like 3DES-EDE and return an 8-byte response, or hash the three output bytes together and send the hash. Using >=16 bytes of challenge would be better, or >=24 if you want printable challenges. >- It doesn't stop replay attacks (replay a fixed challenge, now the same DES > key is used, so replay DES-encrypted session data). You may not be able to replay a given challenge usefully, assuming it's different each time, but MITM attacks work ok after you've cracked the password by dictionary attack in the previous round. >- DES-encryption doesn't provide message authentication against active > attacks; use a MAC too. >- You should use independent DES keys for each direction of the connection. >- Also the DES encryption key doesn't change for each connection.
