Enhancement in OTP generation process for cloud data security using Diffie-Hellman and HMAC - A Review

Cloud Computing is a latest technology and used in every field where storing large amount of data is required. Security is the main problem while storing data. Encryption is used to protect the private data and provides the security in cloud computing. In this paper, the comparison between FHE and FDE is being carried out and a propose scheme is discussed which is used to enhance the security in cloud using OTP generation process in which Diffie-Hellman and HMAC is used to establish a secure channel between the user and the server.
