Non-invasive real-time detection of hardware trojans
Integrated circuit (IC) trojans are a significant security threat to our communications, cloud and IT infrastructure. These rogue modifications to semiconductors can be triggered at any point and represent a latent risk. A hostile government or entity could introduce a hack into semiconductors, that once fabricated could then be embedded into smartphones, telecommunications equipment or IT infrastructure. In addition to being of great importance to chip manufacturers, software companies and systems providers, this issue is recognized as a matter of national security.
The invention described here is a device that monitors the operation of integrated circuits in real time to ensure that the device has not been hacked. It does so by measuring the RF signals emitted from the ICs. It is non-invasive and is envisioned as an in-line process that can be used by semiconductor manufacturers to verify the authenticity of the chips as they are being fabricated. The approach is an application of diamond magnetometry and leverages the research of the Loncar lab to exploit the unique properties of diamond. It is a new technique for ultrahigh spatial resolution detection of near-field electromagnetic emission, using negatively charged nitrogen-vacancy (NV-) color centers in diamond.
