Data access management is an efficient way to make sure the knowledge security within the cloud. However, thanks to knowledge outsourcing and untrusted cloud servers, the information access management becomes a difficult issue in cloud storage systems. Existing access management schemes are not any longer applicable to cloud storage systems, as a result of they either turn out multiple encrypted copies of constant knowledge or need a totally trusty cloud server. Ciphertext-Policy Attribute-based cryptography (CP-ABE) may be a promising technique for access management of encrypted knowledge. It needs a trusty authority manages all the attributes and distributes keys within the system. To guard knowledge confidentially against the honest-but-curious cloud service supplier, varied works are projected to support fine-grained knowledge access management. However, till now, no schemes will support each ne-grained access management and time-sensitive knowledge business enterprise. During this paper, by embedding timed-release cryptography into CP-ABE (Ciphertext-Policy Attribute-based Encryption), we tend to propose a replacement time and attribute factors combined access management on time-sensitive knowledge for public cloud storage.
