Assured Way to Manage Various Controls in Cloud

Abstract

Secure cloud garage, which is a rising cloud carrier, is designed to guard the confidentiality of outsourced statistics however also to offer bendy statistics get entry to for cloud customers whose information is out of bodily control. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is seemed as one of the maximum promising strategies that may be leveraged to cozy the guarantee of the provider. However, the use of CP-ABE may additionally yield an inevitable security breach that's referred to as the misuse of access credential (i.e. Decryption rights), because of the intrinsic “all-or-nothing” decryption feature of CP-ABE. In this paper, we check out the 2 most important instances of get right of entry to credential misuse: one is on the semi-trusted authority facet, and the opposite is at the aspect of cloud consumer. To mitigate the misuse, we recommend the first responsible authority and revocable CP-ABE based cloud garage system with white-field traceability and auditing, referred to as CryptCloud+. We also gift the safety evaluation and further exhibit the utility of our system thru experiments.
