摘要：With the rapid growth of technology, cloud computing become more and more popular. Manyorganizations have been attracted by the variety of services that have been offered by the cloudsin form of resources and applications. Database system is one of the most widely used systemsin industry. Cloud providers offer database-as-a-service to attract more clients to use theirservices. However, executing queries against a cloud database is a challenging process sincedata are stored in encrypted form for security purposes. Cloud database server is responsible ofperforming the user’s query on the encrypted database without any knowledge about themeaning of the requested data to ensure the data confidentiality. Most of the existing methodsfocus on data confidentially and do not guarantee the performance of their techniques. In thispaper, an agent-based system called QinCloud is introduced to execute query efficiently overencrypted data in cloud databases. The proposed system allows users to execute queries on acloud database server without having any intermediate proxy as a trusted server. Nevertheless,the proposed system is designed to support wide range of queries that are performed completelyon the cloud database server side. The proposed system overcomes many issues in existingsystems.
