A secure design-for-test infrastructure for lifetime security of SoCs

International audienceModular design of a system-on-chip (SoC) exposes intellectual property (IP) and SoC assets to attacks in test, debug, and functional modes. We enhance the SoC Design-for-Test (DfT) infrastructure with security countermeasures to thwart these attacks. We first secure IP and SoC assets from attacks in test and debug modes, then reuse the DfT infrastructure to detect attacks in functional mode
