Techniques for virtualization as interprocess communication, synchronization and code obfuscation

摘要

Techniques are presented for obfuscating programs of virtual machines. On a virtual machine hosted by a physical device, a program is run that is configured to execute one or more operations. At a virtual machine manager hosted by the physical device and configured to manage the virtual machine, execution of the program is monitored to detect a trapping event that causes the virtual machine manager to take over operation of the program. Upon detecting the trapping event, a specific operation of the program is performed that differs from an operation implied by static analysis of the program.
