# Any Arbitrary Function

According to the attached reference, does it mean that the adversary computes $PPT(initial~input)$, $PPT(z)$ and $PPT(f_i(x',y'))$?

For example, suppose the corrupted party, in the malicious model, has inputs $x,z$ and it wants to compute $x \land y$, then the adversary's output will be:

$PPT(x)$, $PPT(z)$ and $PPT(x \land y))$. Am I right?

Note: PPT is a probabilistic polynomial-time algorithm

• What is $y$ in your example? If the adversary has only $x$ and $z$, how can it compute $x\wedge y$? – fkraiem Sep 2 '18 at 4:06
• Not really. What you describe is one possibility, but there are others. The adversary can for example output $x\wedge y\wedge z$. – fkraiem Sep 2 '18 at 4:18
