| Abstract(in English) | Various OS vulnerabilities have been reported so far, and the reliability of the OS as an execution environment for programs that process sensitive data is uncertain. Intel SGX, one of the trusted execution environments, protects data from malicious attacks against the OS by executing programs that process important data in an isolated environment called an enclave. However, the data structures that can be transferred between the application host and the enclave are currently limited to simple data structures such as arrays, and handling data structures that contain pointers requires expensive data serialization. This paper proposes a method that enables flexible and efficient data transfer for data structures containing pointers by using fat pointers and memory pools. The evaluation shows that the method can improve the speed of transferring vector and list up to 18.52 times and 19.64 times respectively, compared to serialization. |
