Evaluating the Performance of Reverse Encryption Algorithm (REA) on the Databases

Database encryption is a well established technology for protecting sensitive data. Unfortunately, the integration of existing encryption techniques with database systems causes undesirable performance degradation. It is a crucial technique in the security mechanisms of database. In this paper we propose a new encryption algorithm, which we call Reverse Encryption Algorithm (REA). Our new encryption algorithm REA is simple and yet leads to a cipher. It has achieved security requirements and is fast enough for most applications. REA algorithm is limiting the added time cost for encryption and decryption to don't degrade the performance of a database system. Also, we evaluate the performance of the proposed encryption algorithm REA and compare with the most common encryption algorithms. The performance measure of encryption schemes will be conducted in terms of encryption / decryption time. Experiment results show that our new algorithm outperforms other algorithms at encryption and decryption time.
