Abstract:
With the proliferation of cloud storage, outsourced data transfer becomes an essential requirement for users to migrate their outsourced data from one cloud to another. However, data confidentiality and integrity are big concerns for users when their data are migrating between two semi-honest clouds. In this paper, we propose a secure outsourced data transfer scheme (SODT) to achieve secure data migration in cloud storage. SODT allows users to migrate the remote data from one cloud to another without retrieving the data from the former cloud, such that the data confidentiality and integrity can be achieved during this process. In addition, the cloud can perform secure data erasure after the data are migrated by utilizing the proxy re-encryption technique. Finally, we discuss the security properties including confidentiality and integrity of SODT, and demonstrate its efficiency in terms of the computational and communication overhead.
