Secured and Authenticated Communication in Cloud Using Dynamic Key Exchange Protocol
Cloud computing is a new type of service which provides large scale computing resources to each customer. Cloud computing systems can be easily threatened by various passive and active attacks, because most of the cloud vendors provide services to so many people who are not proven to be trustworthy. Therefore cloud computing systems need to have some security mechanism to protect the user data from unauthorized people. In this paper, the authors proposed a modified Diffie-Hellman Cryptographic Public key algorithm which provides secure and dynamic key exchange for mutual exchange of the session key between cloud user and cloud provider which can be used for secure and authenticated transmission of the user data.
