Re: Labeling Usenet articles.
No, I think he's essentially talking about a 'secure' moderated newsgroup. That is, the moderator(s) would sign each 'authorised' message with a special key, and the newsreader would verify that it was signed by a
Ah, now I understand, thanks. Actually, now that I see what you're getting at, this _does_ seem like a good idea. I think moderated newsgroups can be useful in some circumstances (sure, including a fundie newsgroup), and it would be nice to have a cryptographically secure system of doing this, that cant' be easily circumvented like the present one. And I agree that scripts using PGP do seem capable of doing this, rather then writing some new software. This actually is quite a good idea.
Anyone interested in using PGP with netnews, or with E-Mail in the long run, should be looking at the new internet drafts on security multipart extensions to MIME. Perry Jonathan Rochkind says:

This could also be used as a service to help people pick out usefull technical articles. You need to be able to get the article lists from ftp, mail, modem, or newsgroup, so that people can pay or not pay. Basically, this is support for meta-information. Berzerk.

Carry the information with news. Either within each article (X-Christian-rating) or within a set of control groups for this information to flow in. If you want to charge for the information, encrypt it as it goes out. (300 bit rsa keys + des or blowfish would work well. The value of the information is probably low enough that thousands of MIPS years/month is more than it would cost to buy the keys.) Actually, encrypting it as it goes out has the potential to create huge gobs of information if the system has even a couple of hundered subscribers. Would it be feasable to use a shared key amongst groups of subscribers? Some sort of 'raise your hand while we count users' protocol? Distribution by site with clari* style rewards for turning in cheaters? Ok, maybe Bezerk is right, and we do need to have multiple transports available. But are there protocols which address this sort of broadcast only to subscriber systems that are cheap/easy to implement? How do the cable networks do pay per view? -- Adam Shostack adam@bwh.harvard.edu Politics. From the greek "poly," meaning many, and ticks, a small, annoying bloodsucker.
