CLOUD QUERY PROCESSING ANALYSIS: ENCRYPTION AND DECRYPTION

The usage of clouds to provide data query services is becoming an attractive solution to services that demand scalability and cost minimization. Despite the huge advantages, cloud consumers require their confidential or delicate data to be safe and secured, because violating their private data would be a great concern that is not tolerable. Therefore, corporations who use the cloud services especially the database-as-a-service have tended to encrypt sensitive data for security and confidentiality purpose. Encrypting data would facilitate protecting private information from any violation by the service provider. Several studies have proposed AES and RSA encryption methods. Yet, each encryption method provides a specific level of security which comes with an opposite level of efficiency. Therefore, this work will examine the performance for both encryption methods. The environment setup consists of Microsoft SQL Server as cloud database simulation, and a Visual Studio platform to simulate the local processing of queries. The performance evaluation parameters are time consumption for encryption and decryption. Overall, the results appeared are not significant as each method has its own benefits.
