Cloud Computing Security through Symmetric Cipher Model

Cloud computing can be defined as an application and services which runs on distributed network using virtualized and it is accessed through internet protocols and networking. Cloud computing resources and virtual and limitless and information's of the physical systems on which software running are abstracted from the user. Cloud Computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. To satisfy the needs of the users the concept is to incorporate technologies which have the common theme of reliance on the internet Software and data are stored on the servers whereas cloud computing services are provided through applications online which can be accessed from web browsers. Lack of security and access control is the major drawback in the cloud computing as the users deal with sensitive data to public clouds. Multiple virtual machine in cloud can access insecure information flows as service provider; therefore to implement the cloud it is necessary to build security. Therefore the main aim of this paper is to provide cloud computing security through symmetric cipher model. This article proposes symmetric cipher model in order to implement cloud computing security so that data can accessed and stored securely.
