Abstract:
Commercial cloud storage providers use data deduplication to manage data growth. Many secure data deduplication schemes have been developed and used to protect users’ sensitive data in outsourced storage.
Many scholars studied secure and efficient re-encryption for encrypted data deduplication, and many solutions support dynamic ownership management. In this paper, we demonstrate that the recently designed lightweight rekeying-aware encrypted deduplication scheme (REED) is vulnerable to a stub-reserved attack.
We also propose a CAONT-based data deduplication scheme with efficient re-encryption. Our scheme resists the stub-reserved attack and protects data owners’ sensitive data due to one-way hash function’s intrinsic property.
Data owners only need to re-encrypt a small portion of the package through the CAONT, reducing system computation overhead. Finally, security analysis and experiments prove our re-encryption scheme is secure and efficient.
