Cloud Computing Security by Integrating Classical Encryption

Cloud calculation provides sharing of the spread sources and the services related to the organizations or websites users. As cloud computing of distributed resource is shared in an open environment, the security is the biggest problem in software development. On one hand user controls data and process on his own computer and on the other hand, data services provided by the company and the vendor are kept in the cloud so that the user does not know where to store the data and has no control over it. In this paper, we try a hybrid methodology of modern and classic cryptographic algorithms for providing data security in a cloud environment. (C) 2014 The Authors. Published by Elsevier B.V.
