agileEMSensor
The agileEMSensor is a Ring Oscillator (RO) based sensor designed to detect electromagnetic fault injection (EMFI) attacks on critical circuits. It offers protection against Side-Channel Attacks (SCAs) and tampering through deliberate electromagnetic disturbances. The sensor provides digital outputs to warn processors of intrusion attempts. The RO based scheme is designed to protect a full Root-of-Trust (RoT) or Secure Enclave. This solution is highly configurable with programmable thresholds and internal calibration. It can be tailored to your specifications and is ideally suited for security and monitoring in applications such as in IoT, Communications, Automotive, AI, and general SoCs and ASICs.
Detection of electromagnetic fault injections • Programmable thresholds • Latched and unlatched operation • Latched and unlatched operation • Response time: <5ns • Silicon area: 0.006 mm2 in TSMC N4P
Isolated from power supply noise and temperature • Programmable thresholds • Flexible sensor element integrated into chip back-end flow to protect critical circuitry
