A Novel Cloud Servers Using Attribute Authority to End-user by Encryption

Bojja Nithya, V. Amarnadh, G. Vishnu Murthy


In this paper we proposed to control the access of the large quantity of big facts becomes a very tough problem, especially while massive statistics are saved inside the cloud. Ciphertext-Policy Attribute primarily based Encryption (CP-ABE) is a promising encryption method that allows stop-users to encrypt their statistics underneath the get admission to policies defined over a few attributes of data customers and handiest lets in records consumers whose attributes satisfy the get right of entry to policies to decrypt the statistics. In CP-ABE, the get admission to coverage is connected to the ciphertext in plaintext shape, which may additionally leak some non-public facts approximately quit-customers. Existing strategies best partially conceal the characteristic values in the get right of entry to rules, whilst the attribute names are still unprotected. In this paper, we advocate an green and first-rate-grained large information access manage scheme with privacy-keeping policy. Specifically, we conceal the whole characteristic (in preference to best its values) in the get entry to regulations. To assist records decryption, we also layout a unique Attribute Bloom Filter to assess whether an characteristic is within the access coverage and discover the exact position in the get right of entry to policy if it's far in the get admission to policy.
