Protecting Technique for the Executable File of Virtual Machines

가상기계 실행파일을 위한 보호 기법

The development of a wire and wireless communication technologies might permit easily accessing on various information. But, the easiness of accessing information has basically the problem of an unintended information outflow. An executable file which has key algorithms, data and resources for itself has very weak point in the security. Because the various information such as algorithms, data and resources is included in an executable file on embedded systems or virtual machines, the information outflow problem may appear more seriously. In this paper, we propose a technique which can be protecting the executable file contents for resolving the outflow problem through the encryption. Experimentally, we applied the proposed technique to EVM-the virtual machine for embedded system and verified it. Also, we tried a benchmark test for the proposed technique and obtained reasonable performance overhead.
