UltraSoC and Agile Analog have teamed-up to deliver hardware-based security against ‘analogue interference’ attacks such as power supply or clock signal tampering. The aim is to combining UltraSoC’s embedded on-chip analytics with Agile Analog’s on-chip analogue monitoring IP. As well as voltage and clock glitching, these side-channel attacks can also include deliberate brown-outs and temperature variations, ...
