Abstract
A virtual machine can be implemented by anyone because the interface and other information necessary for implementation are publicly available. Hence, if virtual machine is implemented maliciously, a program operating thereon can be made to operate maliciously instead of operating legitimately. By comparing secret information held in memory and specific to the virtual machine with verification information which a program holds itself, the program verifies that the virtual machine on which it is running has been legitimately implemented and excludes illegitimate virtual machines.
