Active Shield

​​The Active Shield is a fully integrated digital IP protecting System-on-Chip (SoC) against tampering through a metal mesh sensor.

Key Features

Tamper-resistant​
Dynamic detection
Configurable architecture
Adjustable parameters
Silicon proven​

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)

Deliverables

  • VHDL source codes
  • VHDL test benches
  • Synopsys synthesis scripts
  • design specification
