Amplifying Security for Cipher Text Policy Attribute Based Data Sharing

The rapid growth of usage of Digital technology leads to storage of all categories and types of data in digital media. As the technology is very fast in maintenance and also in data theft. We require providing security for the data stored in the digital media various data security techniques have introduced for the last 5 decades, but all those techniques are only key based techniques. All the key based techniques are old and data hackers can hack with various key hacking algorithms and maintenance of all the keys leads to escrow problem in networks. To overcome the problems based in existing technologies we propose a new solution called attribute based cipher text, Providing security to text using various policy based attribute encryption is an approach in which a user with a enigmatical key (containing attributes) is able to decrypt a message only if the attributes in the policy meet those defined in the secret key. The cipher policy attribute based encryption and decryption provides control and security to the outsourced data, it confronts two obstacles. In this paper we provide an applying encryption for data security using user revocation technique, the dynamic revocation of cipher policy attribute based encryption mechanism. The proposed system provides an Amplifying Security for Cipher Text Policy Attribute Based Data security eliminating escrow problems.
