A Framework for Secure Data Sharing over Cloud Based on Group Key Management

Abstract:Now a day’s cloud storage gaining more popularity for sharing of data.The sharing of data with more securely, efficiently and flexible through others in the cloud storage. So that by providing security of sharing data we using cryptography technique. In this paper we are using new public key cryptography technique for provide security of data. This paper basically contains two concepts i.e. key generation, encryption and decryption of data. First one is the key generation we are using improved Diffe Hellman key exchange technique. The second one is advanced cryptography technique for data encryption and decryption. So that by proposing those techniques we can provide more secure, efficient and flexible of sharing data. Information offering is an essential usefulness i
