Abstract:

Cloud computing has become a popular way to store data, but many people are concerned about entrusting sensitive information to cloud providers who may not provide enough user control. With the development of cloud storage system and its application in complex environment, its data security has been more and more attention. However, previous schemes have not adequately protected against Economic Denial of Sustainability (EDoS) attacks, where attackers can consume cloud resources and cost the payer a great deal of money. This lack of transparency and accountability is a major concern for data owners. In order to solve these issues, Fine grained control of access to Cloud Storage using CP-ABE Encryption Technique. The main aim is to secure encrypted cloud storage from EDoS attacks and provide resource consumption accountability by using CP-ABE schemes in a black-box manner that complies with the arbitrary access policies of CP-ABE. Many data owners choose to outsource encrypted data using Ciphertext-Policy Attribute-based Encryption (CPABE) for fine-grained access control. Two protocols are described for different settings and conducted performance. Security is analyzed to demonstrate the effectiveness and efficiency of the presented solution.
