[PDF] Top 20 Perfect Secure Computation in Two Rounds

... It is instructive to take a closer look at the notion of effective degree and see how it relates to existing notions. Recall that effective degree essentially allows the parties to apply arbitrary local- preprocessing of ... See full document
