ACK! My mailbox has been so backlogged that I read this message a month late! *Did* anyone tape the show? I'd really like a copy...maybe to replay on the radio at WCNI (New London, 91.1) if it's really good (if that's o.k....?)... If someone has a tape, please let me know at mrnoise(a)econs.umass.edu, or if you're feeling both ambitious & altruistic, please mail a copy to me at P.O. Box 109, Bozrah, CT...I'll mail you back $$ for the tape & postage. Thanks in advance for any help on this one...

The average person is probably unaware that the folks at the 800 number they're calling can get their number...

Getting the wrong number: That can happen if you're in a PBX with a separate outgoing and incoming trunk group. Particularly if your incoming number is a Direct Inward Dialing (DID) number, which means that people in the Outside World can call right to your desk by dialing (area code +) 7-digits. There is no facility on most PBXs to have DID numbers or other station directory numbers follow outgoing calls, though you might have a call accounting system hooked up to provide information to your company about which extensions are making which outside calls; but again, that's entirely within your own system. If you do have an outgoing trunk group, I would advise setting it up so that incoming calls on that group at least ring to the receptionist's console, and then give out those numbers to company folks who might have reason to need a way to get through in a pinch if everything else is down. Also the outgoing group will be regular loop- or ground-start trunks, and as a last-ditch backup you can terminate them on single-line jacks for use with emergency phones in case of a system crash or an extended power failure. You can also use the outgoing group to provide night service, where calls to various lines in that group would ring to specified extensions in the areas where people may be working after hours. -gg

In fact, after reading some code, I noticed the optimisations are in there, if one compiles with gcc (a few bytes of RS6k assembler makes a significant difference!). Anyway, the particular benchmark I'm playing with (key generation) is now about 20% faster with gmp than with the routines provided with RIPEM.

PGP for 4.3 BSD Unix
by Robert Luscombe 12 May '93

12 May '93

I want to install PGP 2.2 in my Unix account, and may need some assistance. I have never needed to compile anything before, and need some guidance. Actually, if someone has an executable for 4.3 BSD, that is all i really need. Otherwise, would anyone care to help? I really don't know what other info i need to provide to make this easier... i did see in the makefile.unx that there was a target for BSD with gcc; gcc -v here shows that version 2.3.3 is here. Email me if anyone can help. Thanks, bob BTW- Thanks to Eric Hughes for helping me install some stuff. It seems like cypherpunks is a list where people don't only talk, they actually accomplish something, thanks to people like Eric. --Robert Luscombe------------------------------------------------------ - Internet: ral(a)telerama.pgh.pa.us Voice:412/488-0941 - - robert(a)well.sf.ca.us (Finger for PGP Pub Key) - -----------------------------------------------------------------------

BYTE article
by Matthew J Miszewski 12 May '93

12 May '93

Shheeesh. I wasnt even implying the article was bad. To the contrary it was one of the best mainstream articles I have ever seen on the subject. That is why I posted the note to the list. I thought some list members could find the explanations useful. The refinement I was refering to was the authors implied acceptance of Micali's "fair crypto system" as a "solution". I could be wrong, and Im sure I will be corrected if i am, but my feelings were that this system still depended on the trustworthiness of the branches to which the "pieces" of your key would be distributed. If these were all TLAs, we still have a Denning problem, no? I thought I made it clear in the last post that i thought that the article was very good. If not I am sorry. And if your listening Peter, Great Article! --------------------------------------- Matt (Respectfully Questioning in part) mjmiski(a)macc.wisc.edu

That means your office is served by a PBX. With PBX service you have some incoming trunks and outgoing trunks (technically they are lines, but let's ignore that). The number of lines in your company is much greater than the number of incoming and outgoing trunks. The ANI data is the line id of your outgoing trunk. Incoming calls must pass your extension id and connect through an incoming trunk. Neil

BYTE article
by Matthew J Miszewski 12 May '93

Cypherpunks, There is an article about the future of Encryption Regulation in the May 1993 issue of BYTE. Its not TOO bad and our side is at least represented. (With a most excellent spokesman BTW). They offer up a "solution" to the Denning/Privacy Schism. Including Silvio Micali's (I thought someone else had this idea first...) multiple repositories. I recall some talk about this with regard to time released crypto. I think they could use some refining. The author is Peter Wayner and can be reached at pcw(a)access.digex.com. Take it easy on him, I think he is really trying to struggle with issues that we understand already. Lets school 'im guys (and gals). The article actually mentions steganography also...Not bad BYTE.

Well, I've done some comparison between gmp 1.3 and RSAREF (as distributed with RIPEM 1.07) on a RS6000/320 The key generation speeds turned out to be almost exactly the same using the "aixgcc/xlc mixed" version of RSAREF/RIPEM and gmp compiled entirely with IBM's xlc compiler. (for those who haven't poked around in RIPEM, I'll say that this RS6000 version of RIPEM uses the "long long" data type to get 32 bit by 32 bit multiplications with 64 bit results quickly). So, it wouldn't surprise me if some clever person could optimize gmp for the RS6000 and end up with something faster than what's provided in RIPEM 1.07.
