A Unifying Trust Framework on the Secure Computation Outsourcing Problem in Cloud

With the recent advent of cloud computing, the model of outsourcing computations, initiate by volunteer computing efforts, is being revamped. Though the two paradigms differ in several dimensions, they also distribute challenges, stemming from the lack of trust between outsourcers and workers. In this paper, the authors advise a unifying trust framework, where exact participation is financially rewarded: neither participant is trusted; so far outsourced computations are efficiently verified and validly remunerated. They propose three answers for this problem, relying on an offline bank to produce and redeem payments; the bank is oblivious to interactions between outsourcers and workers.
