Abstract: As cloud computing is one of the rapidly growing technologies, cloud storage has been accepted by many people and organizations because it is a more convenient and outsourcing application which is high on-demand. Data owner generally thinks that whether his data is secure or not.So, many research people started designing auditing protocols which concentrates on outsourced data. In this paper, we propose a public auditing protocol with global and sampling block-less verification, batch auditing where data dynamics is more efficiently supported. It is important to note that novel dynamic structure in our protocol consists Doubly Linked Info Table (DLIT) and Location Array (LA).By using this dynamic structure, computational and communicational overheads are reduced, security is achieved. Moreover, numerical analysis and real-world experimental results illustrates that the proposed auditing protocol is going to be more efficient.

Keywords: Double Linked Info Table, Location Array, Auditing Protocol.
