(The above exchange was in bionet.general)

I would suggest that BIOSCI could provide a signature service for anyone
who wants to register.  Authentication requires a trusted key server, and
BIOSCI could provide the server and also could serve as the connection to
the outside world.  A signed article would contain a signature block that
can be verified by software (e.g. RIPEM) and it would contain the public
key which could be verified by comparing it to the list posted regularly in
some bionet newsgroup.  BIOSCI would only post the public keys which is has
independently verified,
e.g. by telephone or by mail.

Ok, I haven't actually fetched RIPEM and tried it, but I could easily
imagine running it against this article and appending a signature block and
my claimed public key.  Most people wouldn't bother checking (although
newsreaders containing RIPEM code could verify that the signature matches
the claimed publick key).  Maybe next week, well, maybe next year...

Probably, the most serious problem is the possibility that someone could
break into my computer and steal the private key. 

I read the other articles about electronic publishing, and no doubt there
are many other problems more important than authentication.  However, as
more people use online searching capabilities, the advantages of online
publication will become more obvious.  Guess I really should unstuff
TurboGopher and try it...

Using signed articles and newsreaders that check signatures would
completely prevent undetected modifications.
