Take the 2-minute tour ×  In the definition below, what exactly
does it mean for the adversary (not even sure that's the correct
term?) to equal one?  $$ \underset{K}{Pr} \left [A^{F_k(\cdot)}
= 1 \right ] $$  Source (Page 22/35?) or Imgur Link  Thanks in
advance!  share|improve this question Asymptotic security

the probability over all $K$ that $A$ given an oracle access to
$F_K(\cdot)$ outputs 1. You usually compare that to the
probability of A ouptputting 1 while having oracle access to a
random function and the difference tells you how well $A$ does
at telling $F_K$ from random  share|improve this answer add
