Thursday noon, SF: Meatspace rally against cyberspace censorship
by John Gilmore 17 Dec '03

17 Dec '03

Monday's rally was canceled on account of rain. There is now a backup location in case of rain on Thursday. Check the web page before you leave, or come to South Park, and the backup location will be close by. See you there! -- John Date: Tue, 12 Dec 1995 18:15:44 -0800 (PST) From: protest(a)wired.com (--Todd Lappin-->) Subject: SF RALLY -- THURSDAY This is an updated announcement for Thursday's Rally Against Censorship, with the current list of speakers. The rally will take place rain or shine, so hope for the best, bring an umbrella, and spread the word. Thanks! *** NETIZENS!! RALLY AGAINST CENSORSHIP *** Thursday, December 14, 1995 at South Park, 12:00 - 1:00 PM San Francisco, California -- Rain or Shine! -- **PROTEST ** PROTEST ** PROTEST ** PROTEST ** PROTEST ** PROTEST ** Amendment I: "Congress shall make no law ... abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble." **PROTEST ** PROTEST ** PROTEST ** PROTEST ** PROTEST ** PROTEST ** It's like illiterates telling you what to read. On December 6 members of the House Conference Committee on Telecommunications Reform approved a proposal to censor free speech in cyberspace. If the measures are adopted, the Net and online media will become the most heavily regulated media in the United States. They *will not* enjoy the First Amendment freedoms now afforded to print media. Instead, online publishers and users will be held to a vague and patently un-Constitutional "indecency" standard. "Violators" will be subject to fines of up to $100,000 and prison terms of up to five years. In response, ALL members of the Bay Area media, online, Internet, new media, and telecommunications communities are invited to participate in a protest rally to express our outrage that the politicians in Congress (which is not even connected to the Internet!) are attempting to destroy our First Amendment rights in cyberspace, and directly attack our livelihoods. Help stop the demagogues in Washington! There is nothing "decent" about denying free speech to us, our children, and our children's children. Preserve our Constitutional rights! Join us! WHEN: Thursday, December 14, 1995 12:00 - 1:00 PM WHERE: South Park (between 2nd and 3rd, Bryant and Brannan) San Francisco. (In the event of rain, an indoor location will be announced) SPEAKERS:Mike Godwin, EFF; John Gilmore, co-founder, EFF; Denise Caruso, New York Times columnist; Jim Warren, online activist; Howard Rheingold, author; Dave Winer, essayist and software developer; Audrie Krause, Executive Director, CPSR; Jonathan Steuer, CEO, Cyborganic Corp; Michael Goldberg, Publisher, Addicted To Noise. BRING: Attention-grabbing posters, signs, and banners that demonstrate your committment to free speech and expression, and your feelings about Congress. FOR UPDATED INFORMATION: http://www.hotwired.com/staff/digaman (Although this event is being organized in the offices of Wired magazine and HotWired, we are *actively* seeking participation and support from all members of the local community. Please forward this message to anyone you think should attend, and to all relevant news groups.) CONTACT: Todd Lappin -- 415-222-6241 -- protest(a)wired.com

Using quantum cryptography to effect covert channels
by Jas 17 Dec '03

17 Dec '03

B2,3 and A1 system (Orange book), use covert channel analysis to prevent leakages of information (intentional or otherwise). This forms a part of enforcing MAC on such systems. well recently i thought of a method to overcome these barriers so covert channels can again be used to transmit and receive from such machines. this method involves using quantum cryptography. "randomization" is one method used to prevent covert channels, however it is this "randomization" that can be used with quantum crypto to not only make covert channels, but also makes the covert channels secure as well as authenticated! basically quantum crypto uses the fact that observing a system modifies the system. this works on machines that use "randomization" as a method of detering covert channels. ObExample, if an admin gets suspicious of certain behaviour on a machine, the machine behaves differently if he tries to investigate it (as a result of "poking around" the machine to see what is going on). this can be used with quatum crypto methods to covertly communicate data (with security and authentification), and if someone attempts to "observe" the behaviour on the said machines, it will break the communication (because the machine behaviour changes, hence breaks the message) rendering the message unreadable. this may slow down communication some, and will need self-synchronization of some sort, but at least you can communicate. this idea is very rough however, and there may be gaping holes in my arguments, but i think it might be an area someone may wish to look into (especially the high assurance types). i really should write a draft paper on this, but i dont really have a good enough understanding of the formal methods to pull it off. however i have got a coining name for this method, "covert quantum channels". just a random thought to throw around...

Re: Time-based cryptanalysis: How to defeat it?

From: futplex(a)pseudonym.com (Futplex) > I don't understand why Kocher's point is correct. For example, why do the > times diverge with the following modification of the modexp algorithm on > pg.2 of the abstract ? > > Algorithm to compute R = y^x mod n: > Let R_0 = 1. > Let y_0 = y. > For i = 0 upto (bits_in_x - 1): > Let M = (R_i * y_i) mod n. > Let R_(i+1) = (bit i of x) * M + > (1 - (bit i of x)) * R_i. > Let y_(i+1) = (y_i)^2 mod n. > End. I posted a similar idea on sci.crypt, but later I realized that Paul Kocher is right. Your algorithm works OK for the first iteration. The amount of work is pretty much constant regardless of whether bit 0 of x is 0 or 1. However, at the end of that iteration R_1 will have one of two different values depending on that bit 0 value. And, the attacker can know these two values, and if he controls y he can even choose them (they will be either y or 1). Now, on the next iteration, the time it takes will be different depending on bit 0 of x. It won't depend on the bit 1 value, but different bit 0 values will cause R_1 to be different. So the time of this iteration will depend on the value of the bit used in the previous iteration, and likewise for the following iterations. If the attacker can choose y, he can arrange that the two different R_1 values will take different times on average for the rest of the calculation. So he finds out bit 0 as before, and from there he can go on and find the other bits. Hal

Re: Potential defense against timing attack on Diffie-Hellman
by Bill Stewart 17 Dec '03

17 Dec '03

Follow-on defense for low-memory smartcards: This is a bit ugly and I'm not sure how much it protects your information, but it's some help for systems that can't store 1024 partial products 1024 bits long, which smartcards generally can't be expected to do :-) Pick k random values K1, K2, .. Kk, where k is some medium-sized number; probably about 10 though maybe more would be better. Calculate Y[i] = Y**2**i, i=1...log x, as before, but instead of calculating r[i] = r[i-1] or r[i-1]*Y[i], i=1...logx, calculate separate subproducts for i={1...K1}, {K1+1...K2}, ... {Kk...logx}, and then multiply those subproducts together. The easy way to do this is keep second running product P, and whenever you reach Kj, set P = P*r[i], and set r[i]=1 for the next round of (Kj)+1...K(j+1). You still need to calculate r[i-1]*Y[i] whether you're using it or not. For added obnoxiousness, at the cost of about 50% more calculation, you could calculate Yinv = Y**-1 mod m, and calculate r[i] and Y**i for i = 1...Kj, calculate through Y[logx] ignoring the r[]s, and then calculate r[i] and Y[logx] * Yinv**[logx-i] for i=logx....Kj+1. #-- # Thanks; Bill # Bill Stewart, Freelance Information Architect, stewarts(a)ix.netcom.com # Phone +1-510-247-0663 Pager/Voicemail 1-408-787-1281

Oh, I see. Is this another one of those "we won't let you make sure that your money is safe with us, you'll just have to trust us" sort of things? Security through obscurity was never a very strong selling suit, especially to those who know that STO very likely hides a very weak encryption/authentication scheme.

A dream which made sense of a lot of things which had seemed to be somewhat out of alignment with the perceptive parameters within which he usually viewed them. He had seen a large, powerful, feathered creature which ruled a huge nest with millions of eggs in it. The great creature worked its will with the eggs, moving them about, throwing some of them out of the nest, consuming others. Suddenly, the eggs began hatching, one by one, more and more rapidly, with a multitude of young fledglings scrambling about, trying to keep from getting crushed, eaten, or thrown out of the nest by the great feathered creature. A few of them pecked hopelessly at the great creature, in vain, but as the numbers of fledgling miscreants increased, the great creature began to wobble, at which time a great mass of the younger and weaker creatures rose up to overwhelm the great creature, sending it spinning out of the nest, and down into the bowels of the earth. Then the multitude of fledglings came together to form a great feathered creature, similar to the first, with each of them becoming a single feather of the new great creature. The creature of many feathers flapped its wings and flew around the huge nest, but never crossing over the outer boundaries of the nest. There remained but a single egg in the nest. The creature of feathers seemed afraid of the egg and would poke and claw at it, ferociously. Each time it did so, however, one of its feathers would turn into an egg and fall into the nest. At first, the creature of feathers would not seem to lose any feathers as the number of its feathers turning into eggs increased, but eventually there were signs that its plumage was deteriorating as it continued its attacks on the eggs, and it began having trouble flying around the nest. The creature began pecking at its own feathers, in a vain attempt to keep them from turning into eggs. The feathers now began turning into eggs en masse, as the great creature began clawing at the eggs and pecking at its feathers, until finally, it fell out of the nest and plunged into the bowels of the earth, screaming, "But who will take care of the orfins?" The Real Guy shook himself fully awake, now seeing visions of the past and the present instead of mere dreams. He saw a dictator falling from power on a small island, asking the impoverished children who were shooting at him, "But who will take care of the orfins?" He saw a General being driven from the compound that held the food donated to the starving people of his nation, the food that he had confiscated and was selling to neighboring counties, for his own profit. The General fled into the barren lands on the outskirts of the compound, shouting over his shoulder, "But who will take care of the orfins?" The Real Guy looked out of his window and saw a multitude of politicians and sheeple attacking passers-by at random, screaming a wide variety of slogans and sound-bytes about 'protecting/saving/taking-care-of' the 'orfins' and the 'children.' They were trampling the children of the future underfoot as they rushed to assault the motley crew of alleged pornographers, pedophiles, drug dealers and terrorists. The screams of the unborn were mixed with the screams of the children of the present when they failed to get out of the way of the attackers, and were knocked down in the rush to protect them. As each of the evil targets perished under the assault of the 'protectors' of the 'orfins' and 'children,' two of the children turned into pornographers, or pedophiles, or drug dealers, or terrorists. "How many of the citizens need to be eliminated or imprisoned in order to protect the children?" The plaintive voice seemed to emerge from within The Real Guy, himself, as did the answer, as he took on the dark visage of Gomez himself, and began to scream, "All of them! Aallll of thheeemmm!" ---------------------------------------------------------------------------- Bubba Rom Dos shook himself awake, trembling. "A dream within a dream." he said, to no one in particular. Jonathan booted down the Trei Transponder, as each of those gathered looked Bubba over carefully, trying to divine whether their further use of the Transponder, after their recent adjustments, was really a wise idea. The remnants of the Magic Circle of the future gathered around the GraphiScreen on the antique oak table, waiting to see what The Real Guy would do with the InformEnergy they had transferred to The Real Guy's digital implant during the course of the wee hours of the morning. They were overjoyed as they saw him type on the screen of his laptop, over a century earlier in the flow of time: The Problem: Group mindthe tyranny of the masses. The Solution: Anarchy! There was a long pause, then The Real Guy continued: The problem within the problem: How to authorize myself to rise above my social self and stand master and captain over my decisions and my actions. The solution within the solution: "To him who does what within him lies" The tattered remnants of the Circle of Eunuchs sat silently, waiting for The Real Guy to continue. One by one, they realized, in their own way, that the question was one that each person would ultimately need to finish for themselves, according to the dictates of their own creed and conscience. Bubba stood and raised his shotglass, in preparation for a toast, and the others did likewise, waiting for him to speak. "Gurdjieff often claimed that the great evil that humankind must fight against was the descent into unconscious automatism. He maintained that man could not consciously do evilthat he or she could only do so by the process of forgetting the divine spark of humanity that lay within, becoming 'man the machine'; a small cog in an automatism which carried a voice of authority that was beyond his own conscious will to overcome, and rule by virtue of accepting the authority and responsibility for his own life, and actions." "To humans" Bubba threw back his shot of 'Bubba's Special Reserve' with a flourish. "ruling the machine." "And not vice-versa." the Cowboy added, as an afterthought, thinking about the battle over control of the InterNet that was shaping up, a century in their past. ---------------------------------------------------------------------------- The Solution Within The Solution ---------------------------------------------------------------------------- The Real Guy awoke from his nap in the early afternoon. He had had another dream, but this time he recognized it as being one wholly his own, as a result of poring over a mountain of posts to the CypherPunks mailing list that morning. It was a short dream. Short and to the point: "Who will take care of the orfins?" ? the Platypus asked, over and over again. "I'll take care of the ones in DC!" shouted Tim May, pressing a large, red button, followed by a blinding flash and a deafening roar. "To him who does what within him lies" The Real Guy laughed to himself as he spoke these words. At least he hadn't lost his sick, twisted sense of humor. He thought about Tim May's comment on the rather loud and poignant statement made by 'his other brother, Tim' (McVeigh). "Broken eggs, and all that" If you want to make an omelet, you have to break a few eggs. When all you have is a hammer, everything looks like a nail. "When all you have is a bomb, everything looks like an egg." The Regular Guy thought about McVeigh-his motivations and intentions. In the end, it was nobody's business but McVeigh's. It was between him and his conscience, him and his God, or godsor him and the great Void. Who was to say, for another? Nevertheless, the great uproar that followed his bombing of the Federal building in Oklahoma City was the response of the huddled masses who had felt the sting of-and feared-anarchy. McVeigh had killed for them, as a soldier in their army. That wasn't scary. He had been part of a larger force of men and women who were killing for them all around the world. That wasn't scary. Now, he was killing for himself, on his own authorityand that terrified them. The government laid his actions at the feet of a recognizable enemy, wanting no more than the average citizen to face the truth of what had transpired on that fateful day when a hundred and sixty-nine (+ one leg) of their group had perished at the hands of a single member of their society. It was the paramilitary, the citizens' militia, bad people who thought that they had the right to defend themselves from the Great Evil, rather than counting on the benevolent state to do so. After spending the better part of a decade of learning how to kill in their government's armed forces, McVeigh had attended one meeting of the paramilitary, and now, his actions belonged solely to them. The press showed us who they were, where they lived, the threat they presented. And most of all, they assured us that we could identify them and eliminate them as a threat if it became necessary to do so. They were an identifiable group that could be murdered by those who were killing for us, if they rose up against us. The truth was too scary to face. The truth was that he was a single man, acting on the dictates of his own conscience, which deemed that those who lived by the sword, should die by the sword. Regardless of whether they hired others to do their killing for them. Regardless of whether they acted on the authority of the 'group.' Regardless of whether they only killed 'bad guys,' or by 'accident' or 'justifiably.' Regardless of whether they only put them in the oven, only turned on the gas, or merely signed the papers resulting in them being taken from their homes and relocated in a death camp. "When Hitler was Fuhrer, the trains ran on time." The Real Guy smiled wryly. The more things change, the more they remain the same. The Nazis confiscated guns from the citizens to protect them. So did the American Congress. The Nazis suspended the rights of the citizens in order to protect them from Communists and Jews and foreign agents. The American Congress suspended the rights of the citizens in order to protect them from Communists, and Arabs, and foreign terrorists. As well as from the drug dealers they, themselves, had created in reality, and the pornography they had created in their own minds. Tim McVeigh had done what within him lay The message he brought was one which was no stranger to the CypherPunks: "We have met the enemy, and he is us." - Alan 'Pogo' Olsen "Beware of Big Brother inside." -Tim C.

While I am unhappy about many aspects of their statement, notably that they use the governments phrase "key escrow" all over the place, the fact is they have placed news about what mischief the government is up to, on a location that get a totally stupendous number of hits. This will notify a stupendous number of people what the government is up to. It is less than they could have done, less than they should have done, but it is still a very big something, and having done this, before the entire internet and all their customers, it is at least somewhat difficult for them to then turn around and shop their customers to the state. --------------------------------------------------------------------- | We have the right to defend ourselves | http://www.jim.com/jamesd/ and our property, because of the kind | of animals that we are.
