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

Abstract

A double-edged sword is the new outsourcing data paradigm to the cloud. On the one hand, it frees data owners from the technical management and makes it easier for data owners to share their data with intended users. On the other hand, TAFC: Time and Attribute Factors Combined Access Control on Time- Sensitive Data in Public Cloud poses new privacy and security challenges. Numerous works have been proposed to support fine-grained data access control in order to protect data confidentiality against the honest but curious cloud service provider.

TAFC: Time and Attribute Factors Combined Access Control on Time- Sensitive Data in Public Cloud Up to now, however, no schemes can support both fine-grained access control and time-sensitive data publishing. In this paper, by embedding timed-release encryption into CP-ABE (Ciphertext-Policy Attribute-based Encryption), we propose a new time and attribute factors that combine access control on time-sensitive data for public cloud storage (named TAFC).

Conclusion

This paper aims to control fine-grained access for time-sensitive data in cloud storage. One challenge is to achieve both flexible timed release and fine granularity simultaneously with lightweight overhead, which was not explored in existing works. We proposed a scheme in this paper to achieve this goal. Our scheme seamlessly incorporates the concept of timed-release encryption into the architecture of ciphertext policy attribute-based encryption.
