Key-cipher policy attribute-based encryption mechanism for access control of multimedia data in cloud storages

Cloud technology is advancing at a rapid pace. Many applications and multimedia data are hosted in the cloud, Security, confidentiality, efficiency key drawbacks of cloud computing. There variety access control systems on market to secure cloud. But generation time major flaw both multi-authority single authority systems. Cipher policy attribute-based encryption (CPABE) one many cryptographic algorithms available for ensuring user confidentiality which provides fine-grained control. It also addreses number issues related attribute revocation, time, handling large attributes. We present mechanism called key-cipher-policy-based ABE (KCP) this article, hybrid approach combines CP-ABE KP approaches result wide range attributes, an efficient process, addresses challenges revocation.
