Re: Linking = Showing = Transferring?

Whoops! I mentioned the "linking to a page that links to a page..." problem without noticing that Joseph Sokol-Margolis had already brought it up. Maybe pornography is not in the page (or resource) but in the browser. For example, I have a "pornography enabled" browser, because I can use it to access pornopages. What if I set up a browser for my child that saw a smaller view of the net that did not include pornopages. That browser would not be "pornography enabled". The limited view could be created from some combination of lists of OK sites & pages, lists of off-limits sites & pages, and certification requirements for those in between (virtual OK lists). I have seen the off-limits lists in association with some blocking products. Frank Stuart wrote, >And then there's the problem of URLs not being static. What may be a perfectly >innocuos link one day may turn into something not perceived as harmless the >next. The blocking (off-limits) lists are then always behind and flawed. Better OK lists might be created by the list publisher having contractual commitments from the site owner. A virtual OK list publisher would publish the key for verifying approved pages that have built-in certs. This would provide the better probability that the browser was not pornography enabled. A page would not show if it had been changed. A problem to be solved would be doing this with minimal psychological time costs to the user. Another is making sure that getting certs would not be such a pain that only a few sites would be on the virtual OK list. Of course, I would not want my kids under 10 to see certain ideological pages and there might not be a market to justify certs. I would have to make my own list or get a cheap blocking list or something from the major-group-with-same-ideological-bent-as-dar ftp site.

> A computer "hacker" is an individual with expertise in gaining > unauthorized entry into computer systems. I heard the special agent in charge being interviewed on NPR this morning. He was very careful to distinguish between "classic hackers" who just poke around for their own edification, and those who are using networks to actively commit crimes. My paraphrase, but it was definitely a praiseworthy viewpoint. /r$

Schneier describes the "cave" analogy in his book, on p. 85, and gives a reference: Quisquater, Guilou, Berson, "How to Explain Zero-Knowledge Protocols to your Children," Advances in Cryptology--CRYPTO '89 Proceedings. The paper is only a couple of pages long and would make a nice scan project for someone, as it has no equations.

It would certainly be a more cost-effective way for the NSA to compromise Mixmaster technology than by brute force. Consider this scenario ... Mixmaster get's bought by the Acme Crypto Company of Ft. Meade, MD. They "improve" it, and offer a new version. It's even FREE (for non-commerical use)! But their "improvements" make it incompatible with previous versions, and so you have to upgrade. The new "commercial" version comes with no SOURCE CODE, of course...
