comment Exact mathematical definition of simulation based security?
Thanks! The first paragraph of your "general observations" cleared this up for me. I'm aware that there seems to be a bunch of frameworks for this. A lot of recent papers seem to concentrate on "composability", where "universal composition" seems like a big thing. Do you know if there's any consensus among cryptographers regarding which current definitions are "right"?
