| Summary: | To keep the data in the cloud confidential against unauthorized parties,a cryptographic access control solution called hybrid cloud re-encryption（HCRE） based on attribute-based encryption（ABE） was introduced.HCRE designed a secret sharing scheme to delegate the task of ABE re-encryption to the cloud service provider（CSP）,which alleviates the administering burdens on the data owner.Experiments show that HCRE can handle dynamic access policies in a more ef-ficient way.Additionally,HCRE does not reveal extra information of the plaintext to the CSP,thus it does no harm to the data confidentiality. |
