Fully-integrated top-metal mesh sensor protecting integrated circuits against tampering attacks
The Active Shield is a fully integrated digital IP protecting System-on-Chip (SoC) against tampering through a metal mesh sensor.
Features
- fully integrated countermeasure against cut and strap attacks
- dynamic detection of tampering attempts
- shield characteristics adjustable through a graphical user interface: security level; mesh number and density; gate number; power consumption;via distribution; routing congestion
- easy integration in typical design flows through RTL files and back-end scripts
- fully compatible with both Cadence SoC Encounter and Synopsys IC Compiler
- silicon proven in 110 nm, 90 nm, 65 nm and 55 nm CMOS processes
- typical power consumption: 5 µW to protect a 2 mm² area in a 65 nm CMOS process
- typical silicon area overhead lower than 3%
- straightforward integration through AMBA APB bus (customized on request)
