摘要：The cloud computing stage gives populace the chance for sharing information resources and servicesalong with the people through internet. In the cloud computing system, both application software and databases aremoved to the large data centres, where the data should not be secure in the hands of providers. IT organizations haveexpressed concerns about the various security aspects that exist with the widespread implementation of cloudcomputing. These types of concerns originate from the fact that data is stored remotely from the customer's location.From the consumers’ perspective, cloud computing security concerns, especially data security and privacy protectionissues, remain the primary inhibitor for adoption of cloud computing services. This paper describes an enhancement forthe already existing data security model in cloud environment. The proposed data security model provides userauthentication and data protection. This makes certain secure communication system and hiding information fromothers. In this model message digest based file encryption system and secure public-key encryption system using RSAfor exchanging data is included. This model also includes onetime password (OTP) system for user authenticationprocess. This structure can be easily applied with all cloud computing layers, e.g. PaaS, SaaS and IaaS.
