How about applets for java-aware pagers or tv-sets that will supposedly show up in the near future? When a crack is found, you can call a toll-free number, give them the code, and win a prize (ala Chinese-lottery). Would it be better to have them all try random keys rather than use assigned keyspaces? Can't keysearches be shorted by half (not that it's that significant, 2^55 rather than 2^56) using complement keys? First thing one should check are the weak and semi-weak keys (a good implementation will avoid them, but that doesn't mean one shouldn't check for them).

I'm _still_ missing the reference here? Just who *seriously* is proposing that 6-year-old children carry guns to school? (I emphasize "seriously* because there is a big difference between seriously proposing this and obviously making a joke, a la "I say we issue them guns after a basic safety class in Kindergarten." And I think someone's (maybe Brad Dolan's, if I remember correctly) point that his daughter carries a gun at school was followed immediately by mention that she is home-schooled, i.e., at his home.) I can imagine certain circumstances in which children could be armed--attacking terrorists on a ranch, Indians, etc.--but no public school in the United States, and probably not any private schools (K-12), allow loaded guns to be carried to schools. I'd love to see this "stupid gun thread" (to use Ernest Hua's term) die, but it keeps living on because some here are mischaracterizing the claims of others. Look, handing out guns to kids playing cops and robbers at age 6 or 8 or even 10 is probably a bad idea, but training kids at even a very young age to respect guns and to understand their dangers and limitations--and their advantages--is proably a good idea. In any case, the hoplophobia of some parents is not adequate reason to stop other parents from training their children under carefully controlled conditions. Getting a carry permit is not easy in any state in the U.S., so the fears that 6-year-olds are openly carrying guns to public schools is unfounded. (Young kids carrying guns to schools _secretly_ is of course a problem. Many of them carry crude guns out of fear that other kids are carrying guns. The proper solution for a kid committing a serious crime with a gun is to severely punish the child--I see no reason why a 14-year-old who murders someone should not get the brand of justice I favor, namely, a fair trial, no appeal except on substantive grounds, and a quick execution if determined to be guilty of first degree murder.) --Tim May Boycott "Big Brother Inside" software!

Re: Decrypt Unix Password File

Get the source for a a Unix-compatible password encryptor, reverse it to make it a decryption program, take the line for a user from the password file, decode it from printable-ASCII format to the binary value, and enter the user's password.

Subject: Public briefing on NRC Cryptography Policy Report in Boston, August 7 Please post widely.... Cryptography's Role in Securing the Information Society A Public Briefing in Boston, Massachusetts Wednesday, August 7, 1996, 10:00 am to noon There will be a public briefing Boston, Massachusetts by the National Research Council on the report. The briefing will be held at the Gardener Auditorium in the State House in Boston on Wednesday, August 7, from 10:00 AM to 12:00 noon. Check http://www.tiac.net/biz/bcslegal for current information. Authoring committee member Elliot M. Stone will be among the presenters at the Boston briefing. Dr. Herbert Lin, study director and senior staff officer of CSTB, will be present. The Boston Computer Society Legal Group, the Boston Bar Association and the Information Technology Division of the Commonwealth of Massachusetts are co-hosts for this event. Questions from the audience will be entertained, and a limited number of pre-publication copies of the report will be available at that time. For further information, please contact Dan Greenwood at (617) 973-0071 or DGreenwood @ state.ma.us. The event is open to the press and the public. If you have suggestions about other places that the committee should offer a public briefing, please send e-mail to crypto(a)nas.edu.

The exact number is, I think, about 2.2x the freqency, which is why >CDs were standardized at 44 K samples per second per channel. No, Tim, the minimum Nyquist sample frequency _is_ precisely 2.000 times the highest frequency to be recovered. However, what is somewhat less well-known is the fact that in order to keep higher frequencies from being "aliased" (reflected to lower frequencies by heterodyne processes) it is necessary to remove (by filtering) any frequency content above that maximum, before sampling is done. Real-world filters (at least, _economical_ ones) do not have instantaneous cutoffs, so it is necessary to provide a little margin, in this case about 10%. Fortunately, a play-only CD only needs output filters, and the input data (the CD disk itself) has already been limited to about 20 kilohertz, so its requirements are not so stringent. The reason so-called "oversampling" started to be done on CD players is that interpolating digitally between samples results in a far higher aliased noise frequencies, allowing either better performance with the same-quality of filters, or equal quality with lower-cost filters, or a combination of them both.
