Abstract :
Data storage is one of the most profitable applications in Clouds. Although a transparent service model is convenient, it may be subject to the loss of data integrity. Our study revealed vulnerabilities in some commercial Cloud storage services. We analyzed the repudiation problem in a Cloud environment. In this paper, we propose a new multi-party non-repudiation (MPNR) scheme to fix the issue. Rationale behind the new scheme and a description of its operation are provided. We also discussed its robustness against typical network attacks.
