Now, you talked about a MAC function (with AES). I previously talked about
encryption.
If I , the only person, uses the MAC key, when I generate more than 2^64 MAC
values (Let's say each MAC value is 96 bits), I have many collided MAC pairs.
But, I am the only one (beside the person(s) verifyi

This is wrong for PRP, right for PRF. It's not tha
