Cost-aware cut-and-choose game is a fundamental technique that has many cryptographic applications. Best existing solutions of this game assumed for simplicity that the number of challenges is publicly known. This paper considers an extension of this game where the number of challenges can be picked probabilistically and hidden to the adversary. Although this small change leads to a linear program with infinitely many variables and constraints, we discover a surprising efficiency solver — using… CONTINUE READING
