  • SYSTEM AND METHOD OF INTERLOCKING TO PROTECT SOFTWARE-MEDIATED PROGRAM AND DEVICE BEHAVIOURS
    Publication number: 20150074803
    Abstract: Methods and devices for thwarting code and control flow based attacks on software. The source code of a subject piece of software is automatically divided into basic blocks of logic. Selected basic blocks are amended so that their outputs are extended. Similarly, other basic blocks are amended such that their inputs are correspondingly extended. The amendments increase or create dependencies between basic blocks such that tampering with one basic block's code causes other basic blocks to malfunction when executed.
