Abstract

Intel SGX is already here, with a strong emphasis on security and privacy. However, it is not free. Studies have shown that it incurs a significant performance overhead to take advantage of the security and privacy enhancement offered by SGX. In particular, it only provides limited physical memory for applications to use SGX. As a result, page faults can be frequently triggered during program execution, especially for memory-intensive applications with a large memory footprint. Therefore, it is imperative to look into possible optimization opportunities to enhance the efficiency of SGX.
