Crypt Cloud: Secure and Expressive Data access by CP-ABE

Abstract

Secure distributed storage, a new cloud management, is designed to give cloud clients with out-of-control data flexible access to information while maintaining the confidentiality of redistributed data. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is regarded as one of the most promising methods for confirming the administration's security. Nevertheless, the inherent "win or bust" decoding feature of CP-ABE may result in an unavoidable security breach known as the abuse of access certification (such as unscrambling rights). In this paper, we research the two major cases of access capability misuse: One is in favor of cloud client, while the other is on the semi-trusted specialist side. To direct the maltreatment, we propose the vitally mindful master and revocable CP-ABE based circulated capacity system with white-box obviousness and auditing, insinuated as CryptCloud+. We also talk about the security investigation and use of our framework in real-world situations
