comment Do random oracles are called even by honest users in the PAK protocol [BMK00]?
I've read Shoup's famous paper "On Formal Models for Secure Key Exchange" and in the paper, due to the use of powerful cryptographic primitives, its construction of the simulator seems to be too simple to show the entire methodology. Do you have any more detailed sugguestion about reading papers? I always seemingly understand the big picture of the ideal/real paradigm and always fall into confusion when I start to read the concrete proof, sadly ...

So private certificate files generated by openssh or given by StartSSL also should be stored carefully. If they are stolen, the private keys are in danger, am I right?

If we assume that the guy does not know the `public key' (he cannot generate any chipertext by himself), does he also be able to use the pairing?
