comment Are there some problems to use pseudo-random number generator in Smart Card?
That's to say I want to find some disadvantages of including the PRNG in smart card.

So, it's better not to include PRNG in the smart card? Actually, I tend to not to include PRNG in the smart card, and I want to find some words to support this.

@AndrewPoelstra:you can refer to the paper "The proof of Theorem 4"

comment Help to understand the chameleon hash function?
@Andrew Poelstra, I'm sorry that you have made a mistake, as $a(t)=(t-t_1)(t-t_2)$ so $a(t_i)=0$. The proof of Theorem 4 is right, you are wrong. you need to reconsider..

comment Help to understand the chameleon hash function?
Now, I'm thinking about making this Non-Interactive Key Exchange to be interactive and identity-based in the standard model, would you give me some suggestions?(Or maybe to cooperate to do this, if you will)

Actually, I don't quite understand what you have said. Maybe the proof of this part can provide some clues, but I think there are some problems with the Proof of Theorem 4.

what software do you draw the map with? It's very beautiful.

comment How does Random Oracle and Standard Model differ?
but proof in the random oracles model is easier than that in the standard model. Although there are some flaws with ROM, in a certain cases where a crptosystem is hard to prove in the standard model, then it's not a bad idea to switch to the ROM. At least, it's better than nothing.

comment Is knowing the private key of RSA equivalent to the factorization of $N$?
when we select $e,d$, generally speaking, if they should $e,d <\phi(N)$ ?
