Cloud Larder is an Increasingly Prevalent Application of Cloud Computing Provide on-demand Outsourcing Document Assistance

Abstract

In this paper, Cloud larder is an increasingly prevalent application of cloud computing, which can provide on-demand outsourcing document assistance for both organizations and individuals. However, users may not fully trust the cloud service providers in that it is difficult to determine whether the Communicating Sequential Processes meet their legal expectations for document security. Therefore, it is critical to develop efficient auditing techniques to strengthen document owners' trust and confidence in cloud storage. a novel public auditing scheme for secure cloud larder based on dynamic hash table , which is a new two-dimensional document structure located at a third parity auditor  to record the document property information for dynamic auditing. Differing from the existing works, the proposed scheme migrates the authorized information from the communicating Sequential Processes to the third party auditor, and thereby significantly reduces the computational cost and communication overhead.
