摘要

The geographic location of cloud data storage centres is an important issue for many organisations and individuals due to various regulations that require data and operations to reside in specific geographic locations. Thus, cloud users may want to be sure that their stored data have not been relocated into unknowngeographic regions thatmaycompromise the security of their stored data. Albeshri et al. (2012) combined proof of storage (POS) protocols with distancebounding protocols to address this problem. However, their scheme involves unnecessary delay when utilising typical POS schemes due to computational overhead at the server side. The aim of this paper is to improve the basic GeoProof protocol by reducing the computation overhead at the server side.We show how this can maintain the same level of security while achieving more accurate geographic assurance.
