| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With the spread of cloud computing, database services, which are basically under a heavy load are now on the cloud. As cloud, cloud service providers have higher permission than database and system administrators, even if the OS and database are robust, reading or leaking of confidential data by cloud service providers is a significant threat yet. A hardware-assisted security mechanism called TEE (Trusted Execution Environment), has been installed in CPUs to protect data and processes from cloud providers.TEE allows programs to run while protecting processes and memory in an isolated environment (trust area). However, as TEE allocates dedicated CPU/memory resources for a protected trusted region, it is not possible to use all of the server’s resources; resources allocated for running OS and other processes, called untrust region, is remaining. Especially in the case of protecting data and processes in a high-load database, situations frequently occur where only the Trust region is overloaded and the resources in the Untrust area remain, resulting in low resource utilization efficiency. Therefore, this study proposes a data protection mechanism for RDBMS that protects sensitive data while effectively utilizing the resources of both Trust and Untrust areas by executing only the elements that handle sensitive data in the Trust area. | |
