Security in Cloud Computing

Abstract

Cloud system involves transferring data from client to server, server to client and processing, storage data in server. As a result of which, data needs to be protected and secure while transferring through the network and in the server of service providers. Cloud system is an emerging technology in which security is the most challenging issue. Due to data security issue with cloud computing many business organization have fear in storing their data in Cloud. So the most challenging task of the business organization is to provide high security for their data since the data are sensible related to their business. This paper tries to summarize general characteristics and trusted security of cloud computing which will help the development and adoption of this rapidly evolving technology. This paper explores some of the basics and privacy issues of cloud computing. We demonstrate a new type of attack that is called “Man in the Cloud” (MITC) Attack. To ensure the security of data, In this paper we proposed a method of providing security that can be prevent “Man in the Cloud ”(MITC) Attack. In this paper we use RSA encryption and decryption algorithm plus auto generated random code verification system to provide two steps security in file synchronization in cloud computing or mobile cloud computing (MCC).
