An explicit integrity verification scheme for cloud distributed systems

Cloud computing encourages the prototype for data service outsourcing, where data owners can avoid cost usage by storing their data in cloud storage centers. The ultimate problem of cloud computing technology is that, the service providers have to protect the user data and services. Secured systems should consider Confidentiality, Availability and Integrity as their primary option. The user encrypts their information to achieve the first one. The second one is achieved in convenient deployment scheme. Last but not the least is integrity. To provide integrity, lots of techniques were discovered, but still the goal is not achieved. In this paper, we propose a novel scheme to achieve integrity goals and we explore how to ensure the integrity and correctness of data storage in cloud computing. The Unique feature of this scheme is finding out which data portion is modified or attacked by the malicious user. In our scheme, there is no need for third-party authority (TPA) and cloud service provider communication in verification. Compared with the existing scheme, it takes the advantage of huge data support and high performance with a simple and easily approachable technique.
