  • Abstract
    In the bounded storage model the memory of the adversarial parties is restricted, instead of their computational power. This different restriction allows the construction of protocols with information-theoretical (instead of only computational) security. We present the first protocol for oblivious transfer in the bounded storage model with errors, i.e., where the public random sources available to the two parties are not exactly the same, but instead are only required to have a small Hamming distance between themselves, and the memory of the (adversarial) receiver is limited. Oblivious transfer protocols were known previously only for the error-free variant of the bounded storage model, which is harder to realize.
