Secure Data Storage in Cloud by using Assymetric Key Management based Encryption

Abstract

Cloud computing is a recently evolved computing terminology in which benefits of the computing framework that given as a service over the Internet. We progress a new methodology for fine grained sharing of re-encrypted data that we call Key-Policy Attribute Based Encryption (KP-ABE). This technique presents a real processing overhead on data possessing for key distribution and the data administration. When fine-grained access control of data is in demand, and subsequently does not scale well. The issue of the same time managing fine-grained, scalability and the data confidentiality of access control is still remain uncertain. We accomplish this goal by using decentralized key policy Attribute Based Encryption (KP-ABE). Extensive study shows that the proposed scheme is highly efficient and secure.
