Combined Access Control of Time and Attributes for Time Sensitive Data in Cloud

摘要

The brand-new pattern of deploy data to the cloud is a two edged sword. On the one hand, it enables data owners to share their information with desired individuals. On the various other hand, it posses brand-new is difficulties on personal privacy and also security protection. To protect information secretness versus the honest-but-curious cloud company, many jobs have actually been suggested to sustain great grained data access control. Nevertheless, till currently, no approaches can sustain both fine-grained accessibility control and also time-sensitive information posting. In this paper, by incorporating timed-release encryption right into CP-ABE (Ciphertext-Policy Attribute-based Encryption), we recommend a brand-new time and also attribute aspects consolidated gain access to control on time-sensitive information for public cloud storage (called TAFC).
