Abstract
A virtual machine can be implemented by anyone because the interface and other information necessary for implementation are publicly available. Therefore, it is possible that by implementing the virtual machine illegitimately, programs run thereon on will be made to operate illegitimately instead of legitimately. A program compares secret information held by the virtual machine with verification information held by the program itself. The program thereby verifies whether the virtual machine that runs the program is implemented legitimately, and is able to reject an illegitimate virtual machine.
