Web2-party secure computation use the free-XOR optimization of Kolesnikov & Schneider (ICALP 2008). We introduce an alternative technique called exible-XOR (eXOR) that generalizes free-XOR and o ers several ad-vantages. First, eXOR can be instantiated under a weaker hardness assumption on the underlying cipher/hash function (related-key security 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.
