摘要
En 中文
To guarantee the integrity of cloud data, plenty of cloud storage auditing schemes are proposed. In cloud storage, when a company is purchased by another company, the corresponding data of the acquired company will be transferred to the acquiring company. In addition, there may be duplicate files between the acquiring company and the acquired company. To solve the above problems, we propose a secure cloud storage auditing scheme with deduplication and efficient data transfer. We design a novel signature transformation method, in which the signatures of the acquired company can be efficiently transformed into the signatures of the acquiring company with the assistance of the cloud. Using the above method, the acquiring company does not require to recompute the data signatures for the transferred data when cloud data is transferred. Furthermore, to improve the efficiency of cloud storage, we use data deduplication method, in which the cloud stores only a single copy of the duplicate files. The security proof and performance analysis show that the proposed scheme is secure and efficient.
