摘要

This paper introduces a new fog-assisted cloud storage which can achieve much higher throughput compared to the traditional cloud-only storage architecture by reducing the traffics toward the cloud storage.The fog-storage service providers are transparency to end-users and therefore,no modification on the end-user devices is necessary.This new system is featured with (1) a stronger audit scheme which is naturally coupled with the proposed architecture and does not suffer from the replay attack and (2) a transparent and efficient compensation mechanism for the fog-storage service providers.We provide rigorous theoretical analysis on the correctness and soundness of the proposed system.To the best of our knowledge,this is the first paper to discuss about a storage data audit scheme for fog-assisted cloud storage as well as the compensation mechanism for the service providers of the fog-storage service providers.
