Security reductions

[ciphergoth]

For the three or so cryptographers on my friends list:

The Goh-Jarecki-Katz-Wang DDH-based signature scheme not only has a tight reduction to the hardness of DDH - it also has a loose reduction to DL using the forking lemma in the same way as Schnorr. I mention this because it's currently my favourite scheme, and the authors didn't know about the reduction...

Saw this, and thought of you :)

I'm probably just showing up how little i know about cryptography, here (which let's face it, could probably fit on the back of a stamp!) but, in case it's of interest:
