Enhanced Secure Data Sharing Over Cloud Using ABE Algorithm

Abstract

Cloud Computing provides a convenient way of sharing of data, which brings various benefits for both the society and individuals. Security is becoming a wide necessity in day-to-day life. Data security is the most obliged security of all. The data in our system is opened to high potential risks. Due to many security reasons we adopt diverse methods. Now everyone is being dependent on the cloud platform for security and storage but even it is vulnerable to various threats. The data inside cloud is not well-secured as it can be accessed by anyone who would have our credentials. But there exists a resistance for users to directly outsource the shared data to the cloud server as the data often contains valuable information. So we propose an Enhanced Security to the data using encryption- The ciphertext-policy (CP) attribute-based encryption (ABE) (CP-ABE) and Byte Rotation Algorithm emerging as a promising technology for allowing users to conveniently access data in cloud computing, giving security to outsourced information, while thinking that client is not stressed while transferring their classified information. Moreover, the privacy of users are protected in this scheme. The security and performance analysis shows the scheme is secure, efficient and privacy-preserving.
