Abstract
When software is initially loaded to RAM, an engineA is installed at the beginning of an otherwise empty area of RAM. When the protected application is called, the engine first creates a series of steps (FIG.D), including a CALL command to a protection block. On reaching the call, the protection blockis executed, to complete various security checks. If these are successful, stepis created and written over the callso that execution of stepsandcan continue as normal. Consequently, the protected software (stepsand) is not exposed to scrutiny unless the security checks have successfully been completed.
