Elliptic Curve [??]
ECDSA [??]
Certicom has some patent claims, I couldn't find out what those are
exactly. Probably - something to do with point compression...
There's a rumor that even some CURVES have been patented by somebody.
So the method is very promising technically, and probably hopeless
"politically".
[Why was I so stupid not to patent a few prime numbers, say - all the
primes between 10^3 and 10^150, for cryptographic purposes? :-]
Diffie-Hellman (X9.42) [??]
I'd like to know the "final" status of DH myself. Anybody?
DES/SK [??]
Not patented. Can be used freely.
If you burn it in chips, you may (but don't have to) send me a sample (:-).
And so on... isn't this done in some other IETF docs?
Should be (:-).
