Due to the semi-trusted service model, customers of cloud storage are always concerned about the integrity of their outsourced data. With Proofs Of Retrievability (PORs), customers are provided with compact proofs that their data are preserved in the cloud without corruptions and are retrievable with convincingly high probability, so they contribute as attractive building blocks for cloud security. Furthermore, it is beneficial of PORs to be used in cloud archive storage which is accessed by customers with low frequency, so that data integrity is checked and enhanced with bringing remarkable burdens.
