comment How can I construct a distinguisher given an inverter?
@K.G. I'm sorry if that wasn't clear, but that's what I meant when I said I'm stuck (I thought it was obvious, I wasn't really trying to calculate the actual probability but simplify it so that it could easily be compared to the probability that you just mentioned). Do you know how is it possible to compare these probabilities ? I would appreciate any help...

comment Question about the definition of a perfect cipher
@mikeazo Yes it is. I don't understand what is the formal definition of a perfect cipher, so I don't even know where to start - what do I need to show ??

comment Question about the definition of a perfect cipher
@curious If it's more comfortable for you, you can ignore b and the requirement of p being a prime. How do you show that it's a perfect cipher ?
