Abstract
The present disclosure relates to software tampering resistance. In one aspect, a method for generating protected code is provided, comprising identifying a primary function in code to be obscured, the primary function being a function used to verify the integrity of the code run-time. The method then comprises generating a finite state machine from the primary function, wherein a state of the finite state machine at a given instance defines an element of the primary function to be executed. The method then comprises distributing the finite state machine throughout the code to obscure one or more areas of the code.
