SecureAccess to Outsourced Databases
Sanjeev Chauhan · IOSR Journal of Computer Engineering · 2013
Data security is one of the fundamental security requirement for outsourced databases in a cloud computing environment.Existing solutions usually suffer from problems such as information leakage, key management, revocation handling and user authentication.In this paper to overcome these security challenges, the proposed scheme uses a modified row-based encryption technique where each row of the database is encrypted using a separate key.The proposed scheme also uses client side memory, and selective encryption to increase performance of the system.The proposed approach also uses a modified Diffie-Hellman key exchange algorithm for establishing secure communication between cloud service provider and the user, inhibiting malicious outsiders.
