more than spread spectrum

There are alternatives to spread spectrum, if we're threatened with loss of freedom to communicate. We could lay our own wires/fibers. We could set up a mesh network of infrared lasers through the air. Last time I looked, there were no laws against shining lights out your window as long as they didn't bother anyone. An infrared laser could hardly bother anyone. We could produce a line of cheap cards to plug into a PC which would do packet routing, using a variety of physical links -- our own wires, lasers, very low range radio, .... Each card would connect to three or more neighbors and become part of the global mesh. Adaptive routing with no global map would suffice for the card and would keep the whole system peer-to-peer with no need for central control and no chance for central tapping. Of course all of these solutions require a high density of users. A college campus might be the right place to start. We could then branch out to cities. I suspect that a place like Chicago or NYC with high rise apartments might be the place to start -- many options for line-of-sight communications. The benefit isn't just for Cypherpunks. It's a free network for the masses -- like the original USENET (with each user donating routing and store/forward) but with unrestricted, low-range, continuously operating physical links. I'll volunteer to do the software for the node card. Does anyone have hardware design/fab to donate to the effort? - Carl

Declan misses the mark on ecash

Declan McCullagh reports in Wired Online, http://www.wired.com/news/ebiz/0,1272,44507,00.html: The more important patent for digital cash, titled "Blind signature systems," was granted in July 1988 and expires in July 2005. Chaum's method preserved anonymity through a statistical technique. It can be thought of this way: A customer of a virtual bank would create a $1 coin by sending, say, 100 coins with random serial numbers first stuffed into electronic envelopes. The bank randomly would open 99 of the 100 envelopes to verify that the denominations were in fact $1 and the customer wasn't trying to commit fraud. After the bank owner was satisfied that the last remaining envelope was likely to be a $1 denomination too, the bank would sign the envelope -- marking it as digital cash -- and return it unopened. Of course this is a completely incorrect description of Chaum's cash system as it has been fielded in DigiCash and eCashTechnologies. It is a botched attempt to describe the "cut and choose" mechanism. But that was only designed for an offline cash system. The purpose of cut and choose was to check that the customer had properly encoded *his identity* in the cash, not that the denomination was correct as is described here. The reason the customer encoded his identity was that if he then double-spent, the bank could determine after the fact which customer had done it because double-spending would reveal his identity. But of course DigiCash was always implemented as an online system, where double-spending is not possible, since coins are always verified at the time they are spent. It never used a cut and choose mechanism for withdrawals, which would have been painfully inefficient. Instead, the customer simply sent one "enveloped" version of a random serial number to the bank. The bank signed the envelope, and the type of signature determined the denomination of the coin. The customer then took the serial number out of the envelope to get his cash. It's far simpler than the description above would suggest. The article also contains a recap of the Chaum/Brands patent wars. It would have been more interesting if there were some reference to new approaches to ecash that avoid the patents, such as the Lucre software by Ben Laurie, based on David Wagner's blinding (http://anoncvs.aldigital.co.uk/lucre/) or the recent proposal at Eurocrypt for a cash/credential system based on zero knowledge proofs without blinding (http://eprint.iacr.org/2001/019.ps or .pdf).

It looks unconstitutional. And dumb too. What is "fully-functional"? Which operating system? I lean towards RTEMS myself. Exactly which material should it screen? You could probably be in full compliance and protest at the same time. Let's say something like : <a href=http://www.mysite.com/fuckfilter.tgz target=_top>Howdy Howdy Howdy Cowpokes! Texas State Law sec 35.102 compliance</a> How does filter sw work? How do you intercept the data between Netscape and the sockets calls? Is it some kind of proxy on the local machine? Isn't there some sockets or perl whiz who could whip up a fully functional freeware gizmo for Linux that filters the word fuck from an http connection and replaces it with peck in italics? That would fix the peckers. Mike Sec. 35.102. SOFTWARE OR SERVICES THAT RESTRICT ACCESS TO CERTAIN MATERIAL ON INTERNET. (a) A person who provides an interactive computer service to another person for a fee shall provide free of charge to each subscriber of the service in this state a link leading to fully functional shareware, freeware, or demonstration versions of software or to a service that, for at least one operating system, enables the subscriber to automatically block or screen material on the Internet. (b) A provider is considered to be in compliance with this section if the provider places, on the provider's first page of world wide web text information accessible to a subscriber, a link leading to the software or a service described by Subsection (a). The identity of the link or other on-screen depiction of the link must appear set out from surrounding written or graphical material so as to be conspicuous. \ . . . \ Sec. 35.103. CIVIL PENALTY. (a) A person is liable to the state for a civil penalty of $2,000 for each day on which the person provides an interactive computer service for a fee but fails to provide a link to software or a service as required by Section 35.102. The aggregate civil penalty may not exceed $60,000. (b) The attorney general may institute a suit to recover the civil penalty. Before filing suit, the attorney general shall give the person notice of the person's noncompliance and liability for a civil penalty. If the person complies with the requirements of Section 35.102 not later than the 30th day after the date of the notice, the violation is considered cured and the person is not liable for the civil penalty.
