An efficient AES and RC6 based cloud-user data security with attack detection mechanism

This paper proposed an efficient framework for text data security. In this framework the data is totally controlled by the user and the user security is controlled by the cloud server. For data security advanced encryption standard (AES) and RC6 algorithms are used. The data is uploaded by the users so the data of the concern user is the admin of those data. Cloud servers are also not allowed to view or update the data without the permission of the concern user. When any user or cloud server wants to access the data of others, the data can be requested. The encrypted data is send after the permission of the concern user. It can be decrypted by AES and RC6 key. Bit rendering and notification can be helpful in malicious behavior detection. The results shows that our approach is better in terms of using the private key, key randomization and provides the support of user to user, user to cloud server and cloud server to user as comparison to the traditional approach.
