The Computational Complexity of Universal Hashing


Any implementation of Carter-Wegman universal hashing from n-bit strings to m-bit strings requires a time-space tradeoff of TS = f~(nm). The bound holds in the general boolean branching program model, and thus in essentially any model of computation. As a corollary, computing a + b • c in any field F requires a quadratic time-space tradeoff, and the bound… (More)
