Key management is very essential part in the cryptographic field where the key must be maintained very secure so that the problem of maintaining of the key is important. The proposed method elaborates the much enhanced and actual key management system along with improved speed and less storage of the key. The policy of managing the key is mandatory for producing a key and required to take care to the storage as well as processing of it in the cloud scenario where security of the data is up most important thing when number cloud users are more in the network to use several applications. Making use of several algorithms by considering Diffie Hellman by combing with the Elliptic Curve will provide most effective in managing of the keys with much lesser key size. In this paper key exchange and shared key generation with Curve 448 is considered the practical results shows that effective key generation and exchange of the shared key. It obtains a 224-bit security level which delivers increased security over Curve 25519, and which has a 255-bit prime number. The proposed elliptic curves which are quicker and simpler to implement than other prime-order curves which are applicable for most of the applications. Hamburg chose the Solinas trinomial prime base p=2448-2224-1 which provides faster Karatsuba multiplication.
