摘要：Cloud computing has been evolved as a next generation computing and changed the way organizations see the IT infrastructure. Cloud computing is paradigm which provides pool of IT resources over internet as a service on rent. It is becoming popular day by day because it reduces operational cost by preventing upfront investment of computing resources and frees the user from maintenance. Clouds providers offer centralized data centers for storing user data. In cloud computing the primary challenge is to gain the trust of the user by ensuring them that their data is safe from unauthorized access. Data security and privacy issues has become a major obstacle to the wide adoption of cloud services. To address this problem, , we proposed the service model based on idea provided by Dawn Song, Elaine Shi, and Ian Fischer. The proposed architecture provides security to cloud data by providing access control, logging, and key management mechanisms. Encryption techniques and third party auditing service are used to provide data security and to protect data integrity.
