摘要：Cloud computing is a revolutionary computing environment, which allows user a flexible, on-demand,and low-cost usage of computing resources, but the data is outsourced to some cloud servers, and various privacyconcerns emerge from it..Attribute-based Encryption (ABE) is a cryptographic conducting tool to guarantee dataowner’s direct control over their data in public cloud storage. ABE is an encryption method used by the user to storethe data in the cloud. ABE is a public-key based one to many encryption methodologies which allows users to encryptand decrypt data based on user attributes Different plans taking into account the Ciphertext Policy attribute basedencryption have been proposed to secure the storage in cloud.Nonetheless, most work spotlights on the informationsubstance security and the access control, while less consideration is paid to the benefit control and the identitysecurity. In this paper focused on better access control permissions for each file based on the attribute of user.Attributes are efficiently utilized for encrypting the valuable data
