Efficient fair conditional payments for outsourcing computations

Abstract


  • The outsourcing computations in distributed environments

    suffer from the trust problems between the outsourcer and

    the workers. All existing solutions only assume the rational lazybut-

    honest workers. In this paper, we first introduce the rational

    lazy-and-partially-dishonest workers in the outsourcing computation

    model. In addition, we propose a new fair conditional payment

    scheme for outsourcing computation that is only based on traditional

    electronic cash systems. The proposed construction uses a

    semitrusted third party T to achieve the fairness and efficiency.

    However, is only involved in the protocol in the exceptional case,

    namely in the case of disputes. Moreover, since neither the secret

    sharing/splitting scheme nor the cut-and-choose protocol is used

    for the generation or verification of the payment token, our solution

    clearly outperforms the existing schemes in terms of efficiency.
