They won't likely go after a specific search site on child porn charges, per se, but they may try to impose restrictions on what gets indexed (ironically, given the name "The Index"). Just as spiders will avoid indexing some pages marked for "no index" (I don't recall the exact syntax), so too could they avoid indexing--and hence making available--sites which the government has declared off limits, either in the U.S. or in foreign sites. To the extent search engines are becoming the de facto entry point to the Web for many of us (maybe even most of us), controlling what they are allowed to index and then report on to customers is a powerful means of controlling speech. I have two predictions: 1. Alta Vista, Excite, etc., will offer services based on parental ratings, religious ratings, etc. Like well-known site filtering services such as SurfWatch and LolitaWatch, these services will present various indices to various customers. To make this clearer, imagine "Alta Vista for Kids," with only kid-friendly (TM) sites and pages indexed. 2. Various governments will try to pressure the various search engine operations to limit indexing of various sites and pages. While of course it is difficult for, say, Singapore to tell Alta Vista what to index, the Singaporans can say they'll put Alta Vista on the list of sites which cannot be accessed easily by Singaporans. Thus will pressure be applied. --Tim May -- [This Bible excerpt awaiting review under the U.S. Communications Decency Act of 1996] And then Lot said, "I have some mighty fine young virgin daughters. Why don't you boys just come on in and fuck them right here in my house - I'll just watch!"....Later, up in the mountains, the younger daughter said: "Dad's getting old. I say we should fuck him before he's too old to fuck." So the two daughters got him drunk and screwed him all that night. Sure enough, Dad got them pregnant, and had an incestuous bastard son....Onan really hated the idea of doing his brother's wife and getting her pregnant while his brother got all the credit, so he pulled out before he came....Remember, it's not a good idea to have sex with your sister, your brother, your parents, your pet dog, or the farm animals, unless of course God tells you to.

I was thinking of storing a reply-key in each remailer. The protocol might go something like this (straw man proposal): (1) Alice picks n random ids (say 160 bits or so) and n random keys. (2) Alice sends the combination <id[i], key[i]> to remailer[i], i=0,n-1. (3) Alice builds a reply block which consists of the remailer return path, each element encyphered with the appropriate key and sends it to Bob. (4) When a remailer processes a reply block element, it removes it from the reply block, looks up the id in its database, decrypts the address of the next hop, removes the database element and forwards the message. If Alice becomes nervous, she sends n "replys" thru each remailer to cause the return path to be destroyed. ------------------------------------------------------------------------- Bill Frantz | "Lone Star" - My personal | Periwinkle -- Consulting (408)356-8506 | choice for best movie of | 16345 Englewood Ave. frantz(a)netcom.com | 1996 | Los Gatos, CA 95032, USA

Science, 30 August 1996: "Enforcing Coherent Evolution in Dissipative Quantum Dynamics" Cirac, Pellizzari, Zoller [Precis] The major obstacle to the preparation and manipulation of many-particle entangled states is decoherence due to the coupling of the system to the environment. A scheme to correct for the effects of decoherence and enforce coherent evolution in the system dynamics is described and illustrated for the particular case of the ion-trap quantum computer. The preparation and manipulation of N-particle entangled states is fundamental to the investigation of basic aspects of quantum mechanics and is the basis of applications such as quantum computation, teleportation, cryptography. and spectroscopy. The error correction schemes proposed so far have focused on preserving a given entangled state (memory errors). We introduce a method to correct for the effects of decoherence in the dynamical proccss of preparation and modification of entangled states (gate errors). We illustrate our scheme in the context of the ion-trap QC. ----- This 4-page paper is packed with equations. We will scan to JPEG for those without access to Science. Send us a blank message with the subject: QDY_nam We have to enlarge the fine-print originals to make readable images, usually in the 150kb range. Does anyone know of a program to do text and equations for easy- reading, easy access to a Web site?
