WebDoes it really matter if we used AND, OR or XOR with the one-time pad? The answer is yes, and it’s extremely important to understand why. Recall from the previous article that AND has a 75% chance of outputting 0 and a 25% chance of outputting a 1. While OR has a 25% chance of outputting 0 and 75% chance of outputting 1. Webin combination with free-XOR. We prove the security of our scheme in Section 4. For all circuits, our half-gate technique leads to smaller garbled circuits than all previous methods (i.e., our row of Table 1 dominates all other rows). For many circuits (i.e., those for which free-XOR previously gave the smallest garbled circuits), our work
