Cloud computing platform gives people the opportunity for sharing resources, services and information among the people of the whole world. In private cloud system, information is shared among the persons who are in that cloud. Because of this, different security related problems have grown in this platform. This paper work has proposed newer security architecture for cloud computing platform, which ensures secured communication system and hiding information from others. DES based file encryption system and asynchronous key system for exchanging information or data is included in this model. This structure is easily applicable with main cloud computing features, e.g. PaaS, SaaS and IaaS.
