Parity Oracle Attack

Question

What happens when the encrypted values is greater than N?

Answer 1

The encrypted value c can, by definition of the encryption c=m^e mod N, not be larger than the modulus N. See the definition of modulus.

If you want to encrypt messages m larger than N using RSA, you have to pick a larger modulus N.
