For the very low end devices, things that run on a AA battery for
10 years unattended, there simply is not enough power to do
any kind of crypto. It's a research problem for device physicists.

Personally, I see a huge leap here. OpenPGP isn't
suitable/designed at all for that application(s) / market(s).
I see some security needs in this market that, like most
security needs, are being generally ignored.
(1) Authentication of messages
(2) Replay protection for messages
(3) Authentication of software updates
Can PGP perform these functions? Is it the best technical solution?
If the answer to both of these is yes, then we should consider
these small systems.
