As Internet technology has grown rapidly, a cloud storage service becomes more very popular and widespread recently. Since there is no guarantee for integrity of data in the cloud storage, audit mechanisms for outsourced data were proposed. However, the conventional audit process requires a lot of computation overheads due to the complex operations used in tag generation and verification. In this paper, we propose a light-weight audit scheme for the cloud storage with efficient cryptographic operations. While keeping high efficiency, our proposed scheme guarantees the consistency of data in the cloud storage. To evaluate the performance of our scheme, we measure the computation costs and the time required for audit process. As a result, our proposed scheme can provide correctness of auditing for outsourced data by an efficient manner.
