Microsemi EnforcIT detects tampering in FPGAs

Microsemi's EnforcIT security monitor IP block allows for additional layers of user-configurable tamper protection and responses to be integrated into the company's SmartFusion2 SoC FPGAs and IGLOO2 FPGAs.

The new security IP allows designers to configure SmartFusion2 and IGLOO2 devices to interface with hardware security mechanisms built into the silicon of these FPGAs. When configured for reporting, EnforcIT security monitor can report to the FPGA a variety of internal security flags and system conditions. When configured to act autonomously, EnforcIT security monitor can respond to malicious FPGA threats and take action, mitigating further attack by protecting or destroying critical data and design. Configurable alarm actions include zeroize, lockdown, and chip reset among others. Safety controls permit the user to delay or cancel automatic responses. The IP allows logic integrity, fault detection, and runtime IP version reporting.
