RE: IS&T Archiving 2006

I'm not sure the LTANS mailing list is the right place to discuss
my paper, but I wanted to point out that you might have long-term
security without using encryption, and long-term notary without
timestamp evidence chains.

This is not the case. Maybe it isn't really a topic for
this list, though. There's an active literature on secret
sharing. Most use secret sharing as a way of managing encryption
keys, but I think it is practical now for the data itself,
without using encryption at all, and appropriate to do so
for a long-term archive.
