Abstract

Computer-implemented systems, methods, and computer-readable media for generating and executing anti-reverse engineering software include receiving at least one of a set of input instructions and a set of input values; creating a deterministic environment; executing one or more functions corresponding to at least one of the set of input instructions and the set of input values while simultaneously generating a set of output values corresponding to the executed one or more functions, wherein the set of output values is generated based on a deterministic function of the computing device executing the one or more functions; and outputting the set of output values.

1 . A method for generating and executing anti-reverse engineering logic comprising:
 receiving, by a computing device, a non-empty set of input values;   executing, by the computing device, one or more functions corresponding to both the non-empty sets of input values and a set of states of the computing device, wherein the one or more functions correspond to a logic to be protected;   generating, by the computing device, a set of output values corresponding to both the executed one or more functions and the set of states of the computing device; and   outputting, by the computing device, the set of output values,   whereby when the set of output values is later used as the set of input values, the method executes the same one or more functions, and   whereby an alteration of the set of states of the computing device results in the method executing one or more different functions.
