  • METHOD AND APPARATUS FOR INCREASING THE SECURITY OF SOFTWARE CODE THROUGH EXECUTION PATH DIVERSITY
    Publication number: 20240078294
    Abstract: A system and method for creating secure software code. Original code is processed to determine memory states, which are dynamic during execution of the code. Selected functions of the code are duplicated and placed in parallel alternative control paths in order to create protected code with increased path diversity. The state of the memory, or a variable derived therefrom is used to select one of the alternative paths during execution of the protected code.
