Abstract

We show that the existence of a coin-flipping protocol safe against any non-trivial constant bias (e.g., :499) implies the existence of one-way functions. This improves upon a re- cent result of Haitner and Omri [FOCS '11], who proved this implication for protocols with bias √ 2-1/2 - o(1) ≈ :207. Unlike the result of Haitner and Omri, our result also holds for weak coin-flipping protocols
