PROJECT TITLE :

TAFC: Time and Attribute Factors Combined Access Control on Time-Sensitive Data in Public Cloud - 2017

ABSTRACT:

The new paradigm of outsourcing information to the cloud is a double-edged sword. On the one hand, it frees information owners from the technical management, and is less complicated for data owners to share their information with supposed users. On the other hand, it poses new challenges on privacy and security protection. To protect data confidentiality against the honest-but-curious cloud service provider, numerous works have been proposed to support fine-grained data access management. However, till currently, no schemes will support each fine-grained access control and time-sensitive knowledge publishing. During this paper, by embedding timed-unleash encryption into CP-ABE (Ciphertext-Policy Attribute-based mostly Encryption), we propose a brand new time and attribute factors combined access management on time-sensitive information for public cloud storage (named TAFC). Based mostly on the proposed scheme, we further propose an efficient approach to style access policies faced with numerous access necessities for time-sensitive information. In depth security and performance analysis shows that our proposed theme is highly economical and satisfies the protection necessities for time-sensitive data storage in public cloud.
