People endorse the nice power of cloud computing, however cannot totally trust the cloud suppliers to host privacy-sensitive knowledge, thanks to the absence of user-to-cloud controllability. to make sure confidentiality, knowledge homeowners source encrypted knowledge rather than plaintexts. To share the encrypted files with alternative users, Ciphertext-Policy Attribute-based encoding (CP-ABE) may be used to conduct fine-grained and owner-centric access management. however this doesn't sufficiently become secure against alternative attacks. several previous schemes didn't grant the cloud supplier the aptitude to verify whether or not a downloader will decipher. Therefore, these files ought to be on the market to everybody accessible to the cloud storage. A malicious assailant will transfer thousands of files to launch Economic Denial of property (EDoS) attacks, which is able to mostly consume the cloud resource. The remunerator of the cloud service bears the expense. Besides, the cloud supplier serves each because the businessperson and also the recipient of resource consumption fee, lacking the transparency to knowledge homeowners. These considerations ought to be resolved in real-world public cloud storage. during this paper, we tend to propose an answer to secure encrypted cloud storages from EDoS attacks and supply resource consumption answerableness. It uses CP-ABE schemes in an exceedingly black-box manner and complies with impulsive access policy of CP-ABE. we tend to gift 2 protocols for various settings, followed by performance and security analysis.
