Data Auditing in Cloud Environment using Message Authentication Code

Cloud computing can be defined as a platform which provides different users an opportunity to store their data in the cloud. This data can be retrieved by any of the users or the service provider of that cloud. Data integrity is one of the major aspects of cloud computing services that prevails in a cloud environment. A cloud user needs to consider about data integrity apart from the confidentiality of data , that is data is not modified or corrupted by the service provider or other users. In this paper, we are going to propose a method to ensure data integrity in cloud environment. We will assure that the data in the cloud has not been altered by using Message Authentication Code (MAC). General Terms Security Management, Auditing, Cryptography and Data Integrity
