This talk by Jean-Francois Blanchette tomorrow (Thurs.) night may be of interest to those of you in the vicinity of western Massachusetts. Check www.hampshire.edu for a map and directions. Enjoy -Lewis --- begin forwarded message --- ISIS <isisGU(a)hamp.hampshire.edu> wrote: Seminar: All About Alice (and Bob, Eve, and Oscar, too): The Research Culture of Cryptography Location: West Lecture Hall, Franklin Patterson Hall, Hampshire College, =>=>=> Thursday, November 5, 7:30pm Modern cryptology researchers have been enthusiastically portrayed in the media as cyberspace's Freedom Fighters, and the fruit of their work, as tangible evidence that computers not only control, but can also liberate. In this seminar, we'll see how this simplistic picture of cryptological research shapes both the public perceptions of cryptology, and cryptologist's perceptions of themselves and their work. Jean-Francois Blanchette will discuss how the culture of secrecy and military intelligence has deeply informed the models cryptologists use to analyze and design security artifacts. He will also discuss how, from a initial concern with communication secrecy, cryptological research has dramatically expanded its scope to encompass digital signatures and certificates, watermarking, e-cash, copy-protection, and other domains. These are all artifacts of much broader cultural and societal import that can be fit under the analytical category of "privacy." Cryptologists, as well as the rest of us, have to imagine and invent richer and more complex representations of what cryptological research is about and what its object is, and to explore other social and ethical paradigms than those offered by privacy and confidentiality. Jean-Francois Blanchette is a graduate student in the Department of Science, Technology and Society at Rensselaer Polytechnic Institute. Trained as a cryptologist, he is now researching and writing about the practices, cultures, and ethics of cryptology. --- end forwarded message ---

When the politicians speak they always make statements which imply that they're speaking to, and being heard by, the whole nation. I just read a notice that less than 40% of eligible voters went to the polls. Since the Republicans are still in the majority, this means that less than one quarter of the voting population supports Clinton as President. And only slightly more than one quarter support Republicans. This would be meaningful to me, if I was making policy: what are all those other people doing? .. Blanc

As soon as you give some entity (e.g. government) the power of force to regulate privacy, you create an entity that will abuse that force and abuse privacy. Plus such regulations are a false security blanket that diminishes demand for true privacy-creating tools (cryptography) -- not to mention you current regime turns around and attacks those tools. Being bound by the law of economics is generally a good thing. Matt

If you're talking about the people who didn't vote, they're trying to keep from going under. Probably working two jobs, keeping the kids in school and out of trouble, saving for college, paying the house morgage off, etc. Who's in office won't make a whit of difference to any of that. It's irrelevant. If you're talking about the politicians, they're laughing their ass off on the way to the bank to cash their tax-derived income. ____________________________________________________________________ To know what is right and not to do it is the worst cowardice.

No they are not, nor will they necessarily recognize the economic consequences of their actions before they entirely self-destruct or mutate only to do it again. History shows this. I generally use the economic/political distinction as made by Franz Oppenheimer, and furthered by Rothbard, Rand, etc. In that context they are a political actor, not an economic one. I purposefully ignored the prospect of corporations using coercive force to prevent privacy, it is rather improbable and still preferable to government coercion -- but note they do use coercive force today preventing privacy, but government is their instrument of force. Jim Choate wrote: > You need to look around, the government has NO monopoly on force. They have a *legal* monopoly on force (within a state). You do not generally consider the black market in determining monopolistic conditions, and in fact the existence of a black market in a segment generally points to a coercive monopoly in the public one.

It depends on the regulation and how it's applied. You simply can't equitably apply the statement that all regulation is bad because it's equaly clear that no regulation has its own pitfalls and abuses. > Being bound by the law of economics is generally a good thing. Yes, provided you have 'fair competition' which you can't in a free market. Provided all companies and their management operate within some sort of ethical guidelines, which they won't (and don't).

False distinction. Politics is about control and power, and in human society that breaks down to force and money. > I purposefully ignored the prospect > of corporations using coercive force to prevent privacy, it is rather There you go again, confusing privacy with economics... > improbable and still preferable to government coercion -- but note they do > use coercive force today preventing privacy, but government is their > instrument of force. True, but that isn't a function of regulation per se only the particular type of regulation that we have implimented. You're arguing from a specific example and trying to extrapolate to a general rule and it don't fly. > Jim Choate wrote: > > You need to look around, the government has NO monopoly on force. > > They have a *legal* monopoly on force (within a state). No, they don't. It is perfectly legal for an individual to own a weapon. There is also a clear distinction between the local police, your state police, federal agents, military, etc. Lumping them all into one generic category is a disservice and is unrealistic (especialy since they are often in adversarial roles) if we really want to understand how our society works and where we can take it. > You do not generally > consider the black market in determining monopolistic conditions, and in > fact the existence of a black market in a segment generally points to a > coercive monopoly in the public one. No it doesn't. It points to the fact that individuals want to participate in some activity that some other party doesn't want to occur. It does not imply that the regulating party wants the potential income from those activities. Further more, even in a free-market there will exist black markets. It's always cheaper to buy stolen merchandise than legitimately purchased merchandise. The aspect of a free-market is that there is no consequence from such actions (unless you want to admit to allowing corporations to have their own hit squads). Again, a function of human psychology and not economics or political systems. ____________________________________________________________________ To know what is right and not to do it is the worst cowardice.

Last time I checked a laser or a maser (both are radio waves strictly speaking) travel LOS. The scattering comes from beam divergence and incidental refractions and reflections from the molecules in the air and supported detritus. > Microwave ovens work by having the waves bounce around inside a box.

In most microwave ovens there are definite dead-spots (corners and the exact center of the area are notorius). > An open top box will not work. If the microwaves (for example) are transmitted parallel to the open side it might very well work just fine. It's going to depend on a variety of factors that will preclude such a blanket statement from being valid. > Unlikely to prevent someone from figuring out what the real signal is.

For these to work there must be a time-correlated aspect to the signal that doesn't appear in the noise. If you mask the signal with the same sort of time correlated cover (eg phase shifting) it also might work. > And we are talking about 100 dB sorts of suppression. Mere factors of a few > with fake signals and noise are meaningless on this scale. The absolute magnitude isn't really important. Most of the signals that are emitted by a computer are not in the 100dB dynamic range (@2x=3db that's a signal range of 1:33) , more likely 40-50db if that. For a TTL (5V) signal it barely covers 3dB (LOW is <2.5v and a high is >=4.75). There simply is no way in hell a signal with a 3dB range is going to emit a rf signal that is 100dB. There are other logic families with wider dynamic ranges (eg CMOS w/ 18V Vcc can be nearly 18V or approx. about 12dB). ____________________________________________________________________ To know what is right and not to do it is the worst cowardice.

Cryptography Study Group - Palo Alto
by John Cutler 17 Dec '03

17 Dec '03

A Palo Alto-centered cryptography study group has been been formed. Our first project is to read Schneier's "Applied Cryptography." We meet a couple times each week to go over assigned reading and to play with ideas about cryptography. While the current participants all have a professional interest in the field, we are loosely organized. Readings are decided at the previous meeting giving us the flexibility to explore particular ideas in depth. Please contact me if you would like to join us. John Cutler jcutler(a)via.net
