comment How to prove that a ciphertext is encrypting multiplication of two values?
What do you mean by generic proof argument? How i can convince that the non-DLP encrypted value lies in predefined range?I just make a huge assumption that the encrypted values is the witness for a proof that is submitted independent from the ciphertext?

Yes but what if you don't want to use DLP based public key encryption schemes?

comment Difference between computational and statistical indistinguishabilities
Also statistical indistinguishability is stronger than computational indistinguishability as there is not restriction on the computational power. So it might be the case that a scheme preserves computational indistinguishability but not the statistical indistinguishability

$f(x)$ is defined $mod N^2$ as well

comment Are those two distributions indistinguishable?
I don't understand your comment. you are given 1 number. Either in the first form or in the other form and you have to decide whether or not there exist a quadratic residue for this number.

comment How does OAEP improve the security of RSA?
How the legal receiver gets rid of the pad if he doesn't know the $r$? It just spits the $#pad$ bytes? That implied a public knowledge of the pad length.

comment Advantages of bilinear map
Maybe i should rephrase: "The first use of pairing that we know is not for construction of cryptographic primitives but to break some hard assumptions as the DL in specific groups"

comment How do I calculate the private key in RSA?
These are standard techniques you can find in all books.We say the same thing.In order to compute the inverse you can use the extended euclidean algorithm
