A New Approach of Multi Authority Data Access Control for Secure Cloud Storage

Abstract

Now days, many users are storing their large amount of datas in cloud, as a results of it provides storage flexibility. But the foremost drawbacks in cloud square measure information security. Cipher text-Policy Attribute-based cryptography (CP-ABE) is believed to be one in all the foremost acceptable technologies for data access management in cloud storage; as a results of it offers information householders lots of direct management on access policies. Throughout this work to propose associate data access management for multiauthority for validating the integrity of associate un-trusted and outsourced storage by third party auditor. In addition, this project proposes methodology based on probabilistic question and periodic verification for up the performance of audit services. It ensures efficiency of security by protecting from unauthorized users. These experimental results not alone validate the effectiveness of these approaches; but
conjointly show our audit system verifies the integrity with lower computation overhead and requiring less extra storage for audit knowledge.
