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

Now-a-days, 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 the authors using cryptography technique. In this paper, they 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 they are using improved Diffe Hellman key exchange technique. The second one is advanced cryptography technique for data encryption and decryption.
