The new model of subcontracting data to the cloud is a two-edged sword. On the one hand, it frees data owners from the official management, and is easier for data owners to share their data with proposed users. On the other hand, it brings about new experiments on privacy and security protection. To protect data privacy against the honest-but-curious cloud service provider, numerous works have been proposed to support fine-grained data access control. However, till now, no schemes can support both fine-grained access control and time-sensitive data publishing. In this work, by establishing timed-release encryption into CP-ABE (Cipher-text Policy Attribute-based Encryption). I propose a new time and characteristic issues combined access control on time-sensitive data for cloud storage. Based on the proposed scheme, I further propose an efficient approach to design access policies faced with various access requirements for time-sensitive data. Extensive security and performance analysis shows that our proposed scheme is highly efficient and satisfies the security requirements for time sensitive data storage in public cloud.
