Can anyone point me towards a program that's freeware or shareware that will overwrite all the unused i.e., "trashed" space on my hard drive(s)? I sincerely apologise if this is a faq. I know norton's will do it but I don't presently have that installed on my machine. Thanks oodles, joe j. ercole ny, usa vox: 516.681.3548 e-mail: joee(a)li.net finger for pgp public key

Random SuperHacker can get g^X, and g^Y, but not g^XY. It's _not_ free after 1997! I thought of it last fall, was surprised I couldn't find it anywhere in the literature, given that it's pretty obvious, but eventually found that a guy from Siemens had patented it in Germany and then gotten a US patent in ~1994. Unfortunately, he phrased it in terms of "commutative hash functions", with g^X mod p as an example, so it's more general. He also extended it to do two-way authentication (obviously the process can be symmetrical if the user has a stored g^W from the server and can send a challenge, but he found a way to save a step or two.) I developed it because I was looking for a way to do authentication-only public key stuff so the code would be exportable - this approach doesn't generate a shared secret (since the otherwise-secret g^XT is exposed as the response to the challenge.) However, it's possible to extend it to preserve the shared secret - instead of sending response g^XY mod p, send Hash(g^XY mod p) and have the login server validate that. One advantage is that the hash can be much shorter than the whole g^XY mod p, e.g. 32-64 bits instead of 512-1024. And you can now use (g^XY mod p) as a session key (for encrypted sessions) or an authenticator (e.g. send Hash(Data,sequence#,sessionkey) as a MAC for each packet. #--- # Thanks; Bill # Bill Stewart, Freelance Information Architect, stewarts(a)ix.netcom.com # Phone +1-510-247-0664 Pager/Voicemail 1-408-787-1281 #--- # Export PGP three lines a time --> http://dcs.ex.ac.uk/~aba/export/ M0V]N9W)E<W,@<VAA;&P@;6%K92!N;R!L87<@+BXN(&%B<FED9VEN9R!T:&4@ M9G)E961O;2!O9B!S<&5E8V@L(&]R(&]F('1H92!P<F5S<SL-"F]R('1H92!R M:6=H="!O9B!T:&4@<&5O<&QE('!E86-E86)L>2!T;R!A<W-E;6)L92P@( T*

WIL_mil
by John Young 17 Dec '03

17 Dec '03

Garry Wills, the historian, writes a thought-provoking essay in The New York Review of Books, August 10, 1995, on "The New Revolutionaries," about the militants and the political and social grievances that undergird their movement -- many of which are shared, Will states, by a wide spectrum of the populace discontented with the government: The suspicion that government has become the enemy of freedom, not its protector, crosses ideological lines. Liberals point to FBI plots against American citizens like Dr. King, to CIA experiments with LSD on American citizens, to the Defense Department's use of Americans as guinea pigs in nuclear testing. The right sees assaults on liberty from the Bureau of Alcohol, Tobacco and Firearms, the Department of the Interior, the Occupational Safety and Health Administration. Many people resent the fact that government has become a dictator of the terms of societal conduct -- in welfare programs, in affirmative action and other preferential attitudes toward citizens' rights, in schools that seem to have a "multicultural" or antireligious agenda, in confiscatory taxation, in the keeping of elaborate files on citizens' activities, in various agencies' surveillance techniques and bribing of informers. Wills goes on to review these grievances: Taxation. The jury system. Regulations. Police power. Schools. Family. Religion. Citizen militias. Constitutionalism. Corruption. Guns -- discussed at length. And, he summarizes in closing: With the end of the cold war, the justification for government activism has been taken away. If the government is only good for fighting Communists, and it no longer fights Communists, then what good is it? No convincing answer comes from above -- which lends the answer from the depths its new plausibility: It is good for nothing, and citizens must take their own lives in hand again, vindicating their own liberties. Right or wrong, the armed patriots at least have arguments they can believe in wholeheartedly. They take the mood of post-cold war drift, of Perotista resentment, of disillusionment and economic shakiness, of fin de siecle fear, and change it into a plan for doing something about one's gripes. The militias and their supporters are not the most central social symptom of our time, but they are among the more dramatic symptoms of a general crisis of legitimacy. The authority of government can no longer be assumed. It has to be justified from the ground up. Many people who are not militants or conspiratorialists can agree with parts of this analysis. Libertarians wonder why people who keep to themselves should be bothered. It is no longer so "extreme" to believe that our government is the greatest enemy to freedom. We see this in a new hatred of government agents (who fear for their lives in western states). Or in the unprecedented vilification of the head of our government. The fierce contempt for Hillary Rodham Clinton, for the Attorney General (called "Butch" Reno on bumper stickers), for "Condom Queen" Joycelyn Elders, reflects misogyny rebelling against feminism's gains; but it is also a sign that the office of the presidency itself may now incur a contempt as routine as the respect it once commanded. The heaping of filth on the personnel and symbols of government has a delegitimating effect in itself; and the assault is joined to the disillusion, anger, and disorientation that have marked recent electoral behavior. Where the heated deny legitimacy and the cool are doubtful of it, a crisis is in the making. WIL_mil (about 50K, in 3 parts)

Re: NSA, Random Number Generation, Soviet Codes, Prohibition of
by Ulf.Moeller＠hamburg.netsurf.de 17 Dec '03

In the book I mentioned there is a quotation of D. Kahn, The Codebreakers, from 1967: "Interestingly, some pads seem to be produced by typists and not by machines. They show strike-overs and erasures - neither likely to be made by machines. More significant are analsyses of the digits. One such pad, for example, has seven times as many groups in which digits in the 1-to-5 group alternate with digits in the 6-to-0 group, like 18293, as a purely random arrangement would have. This suggests that the typist is striking alternately with her left hand (which would type the 1-to-5 group on a Continental machine) and her right hand (which would type the 6-to-0 group). Again, instead of just half the groups beginning with a low number, which would be expected in a random selection, three quarters of them do, possibly because the typist is spacing with her right hand, then starting a new group with her left. Fewer doubles and triples appear than chance expects. Possible the girls, ordered to type at random, sensed that some doublets and triplets would occur in a random text but, misled by their conspiciousness, minimized them. Despite these anomalies, however, the digits still show far too little pattern to make cryptanalysis possible." -- Ulf Möller * um(a)ulf.mali.sub.org * 3umoelle(a)informatik.uni-hamburg.de PGP key fingerprint: B6 4F 97 28 8F C0 54 C3 A6 10 02 2F B9 31 78 14 "When cryptography is outlawed, bayl bhgynjf jvyy unir cevinpl!"

Canadian Export Controls
by Richard Martin 17 Dec '03

17 Dec '03

This is a notification of the first creation of a few pages describing Canadian Export Controls. Any one who has read the printed document [Canada's Export Controls] will realise that it's almot word-for-word, but there's some use for that. In any case, they currently live at http://www.io.org/~samwise/crypto/ It may be that they'll move, but http://www.io.org/~samwise/interesting.html#privacy should always have a pointer to them. comments, bugs, spelling errors, contributions to rmartin(a)alias.com The pages were written this evening. Tomorrow morning I'll look at them, scream, wonder what I was thinking, and rewrite them. This is so that there'll be a few more screams. :) frodo =)
