Secure Multiparty Computation. Consider the protocol for Garbled circuits that we have seen during the lecture. Let Alice be the participant that encrypts the
circuit and Bob be the participant that runs the circuit.
Suppose that Alice and Bob want to compute the output of a function F for two pairs of inputs (i.e.a=F(x1,y1) and b=F(x2,y2), where Alice knows x1 and x2 and
Bob knows y1 and y2. Suppose that Alice encrypts the circuit representing F once, that she sends the resulting garbled circuit to Bob, and that she allows Bob to
obtain the encryption of both inputs y1 and y2, so that he can run the same circuit twice. Is this secure for Alice? Motivate your answer, in general or with an
example.
