A Secure and Efficient Way of Accessing Encrypted Cloud Databases Using Adaptive Encryption Scheme

Seethal K S | Siddana Gowda

Abstract: Now-a-days cloud computing is showing consistent growth in the field of computing. Users can utilize these services on pay-per-use basis. Database-as-a-service is a one type cloud computing service. DBAAS service provides users with database access without need for setting up physical configuration or installing software. But main drawback of DBAAS is, when data is exchanged in cloud, there exists the problem of disclosure of privacy. The idea is to build privacy preserving storage model where data sharing services can update and control the access and limit the usage of their shared data. Preserving privacy is an important issue for cloud computing and it needs to be considered at every phase of design. This paper proposes a metadata based data segregation and storage methodology along with an encryption technique to provide additional security. Here additional security is provided by SQL aware encryption scheme or adaptive encryption scheme. This would serve as a helping note in the progress of strengthening the privacy preserving approaches in cloud computing. This paper also compares both encryption schemes.
