I don't understand--what would signatures on a nym's key be good for? If I sign your key named "Bruce Baugh", I'm basically saying that I feel confident that this key really _does_ belong to Bruce Baugh. Others see my signature, and say "Jonathan, he's a groovy guy, if he feels confident that this belons to Bruce, well, he's probably gotten the fingerprint directly from Bruce in person, and I'm happy to use this key to send mail to Bruce." If, on the other hand, I sign "Toxic Avenger"'s key, then what benefit is this for third parties? Since Toxic Avenger is, by intention, _not_ linked to a real person, I'm not saying that I feel confident that this key really belongs to any particular real person. What am I saying?

I think this is likely to be an oversimplification. While there are probably a number of people in e.g. FBI, DEA, DOJ who want to restrict domestic crypto, I suspect there are also a number of people in e.g. NSA who are sincerly interested in using SIGINT to protect the US from foreign threats and want strong domestic crypto as part of that protection. As always, public policy is a compromise between competing interests (INSIDE the beltway). However, the current policy is a holdover from the days when strong crypto was a closely held trade secret. Since this assumption is no longer true, the policy becomes more and more disfunctional every day. ----------------------------------------------------------------- Bill Frantz Periwinkle -- Computer Consulting (408)356-8506 16345 Englewood Ave. frantz(a)netcom.com Los Gatos, CA 95032, USA

disk randomness
by Donald T. Davis 17 Dec '03

17 Dec '03

rich salz posted to this list a message i sent him about a portable way to gather disk-noise for a true rng. he also was kind enough to forward a reply to me from the list, because i wasn't subscribed at the time. the reply's author pointed out that my approach is not a practical one, and that NOISE.SYS gathers disk timings and other noise more efficiently, anyway. now that i'm subscribed, i'll answer on my own behalf: i agree that my algorithm isn't practical. in fact, that's why i agreed to rich's request that i let him post my message here. i don't recommend paging-timings to my clients, because it's not a workable approach for production-quality code. memory-paging's only virtue as a noise-source is that it's uniquely portable. i failed to emphasize this, in the message rich forwarded for me. the code needs no device-specific calls, and the only OS-specific call is the gettime() call. even with this virtue, i don't recommend it as a production-quality algorithm, unless the process that needs the rng is already memory-bound. i'm sorry that my original msg was unclear on this point; that's my fault, not rich's. by the way, i think the "interesting work" of mine to which rich referred, is my paper on disk randomness, which appeared in the crypto '94 proceedings. it presents work i did at mit from '88-9, and shows mathematically why disk-timings can contain true entropy: a disk's speed variations come from air turbulence, which now is known mathematically to be unpredictable in the long run. my coauthors were p.r. fenstermacher, a chaos-theory physicist, and r. ihaka, a statistician. -don davis, boston

Re: NSA says strong crypto to china??

Who would have thought? An NSA > remade in Tim May's image. I suspect that the NSA was thinking in our terms long before many of us were aware of cryptography. I actually think that in many cases, their behavior is perfectly rational. Their goals are merely different. If you are in SIGINT, I believe that the possibility of totally losing a valued intelligence tool must heavily weigh on your mind. Of course, they are hardly monolithic, and different groups at the NSA necessarily have different goals. Once SIGINT becomes much harder regardless of their previous attempts to stop it, I suspect that the NSA will become a friend and not an impediment. By that time, of course, the "we have to protect our people" types will be the only ones producing results and getting funding, and the "we have to gather information" types will have long ceased to produce. Thats probably a decade or more off, though. --------------- I suspect that the NSA can basically be divided into four groups: A. Those who are interested in protecting American individual liberties, and are thus (possibly potential) allies. This bunch may have a subgroup of those who already are allies, who have unfortunately been rather unsuccessful (or perhaps we simply haven't seen their successes). B. Those who realize about the potentials for individual liberty from cryptography, but believe that something else about America is more important. For instance, they may believe that the voters in a democracy should be able to institute whatever rules they like. Various left- and right-wing viewpoints are also possible here; the former would include worrying about lost tax dollars because of wanting big government, the latter would include concerns about pornography, etcetera. C. Those who are in the NSA because they want power, and strong cryptography's dissemination would hinder this. This group is likely to be concealed as one of the other groups. D. Those who haven't thought about it, and are simply following orders. I suspect that this is the largest group; while the overall level of intellect at the NSA may be higher than in the average population, the intelligence mindset of "need to know" may be keeping many people from realizing everything the NSA is doing. -Allen

I've heard some people claim that the > government could come after us on the grounds that we were taking > part in a conspiracy to export strong crypto. Why not just print out all of the source code to Navigator (crypto and all) in a nice OCR font? Paper is exportable. Then you would 'only' have to scan it back in and debug it. andrew

Re: IPSEC == end of firewalls

Discussing firewalls, ses(a)tipper.oit.unc.edu (Simon Spero) writes: >What do you need as well as crypto before you can remove all firewalls? What firewalls do is they allow an independent group of people to track external network access and enforce rules over a large population of hosts. Given that just about any security installed on a workstation can be overcome (inadvertently or consciously) by someone with physical access to it, I doubt firewalls will ever go away entirely. Today's techniques will no doubt evolve and change in varous ways over time. But I'd be surprised if the function went away entirely. Until Netscape came out I suspected that desktop crypto wouldn't make the bigtime soon, simply because there are too many ways to do it wrong. Netscape has demonstrated that doing it wrong is no impediment to deployment. Organizations that want to do crypto well are probably going to concentrate crypto services in a few closely managed hosts to reduce the risk of messing things up.

Over time, some nyms take on a distinct identity of their own. In fact, some do it very quickly, a with the neo-Nazi twits now arguing in favor of rec.music.white-power over on news.groups, some with distinct "voices". The thought, therefore, as I imagine it would be "You don't know I am in person, but you can count on me to be who I am, with this style and set of views, and I say that this guy is another actual person with the same."
