Security

Today’s demanding applications not only have to meet the functional requirements, but also meet them in a secured

way. Security starts during silicon manufacturing and continues through system deployment and operations.

Microchip’s PolarFire SoC FPGAs represent the industry’s most advanced secure programmable SoC FPGAs.

Design Security

Protecting your design starts with wafer manufacturing and continues through the deployment of the end product.

The following are key features that provide state-of-the-art supply chain assurance and IP protection benefits:

• Secure supply chain management through the use of hardware security modules (HSMs) during wafer test and

packaging

• Supply chain assurance through the use of a 768-byte digitally signed x.509 FPGA certificate embedded in

every FPGA

• AES256-encrypted CRI DPA countermeasures patent protected, bitstream, and key management protocols

• Built-in tamper detectors: voltage monitors, temperature monitor, clock glitch detectors, voltage glitch detectors,

protective meshes, and bus scrambling

• Data integrity through built-in cryptographic digest capabilities

• Zeroization capabilities for all on-chip memories and the FPGA fabric

• Integrated PUF for key storage

• 56 KB of PUF protected sNVM

– Secure reprogrammable keys using non-volatile memory

8.1.1

Tamper Detectors

PolarFire SoC FPGAs integrate numerous on-chip tamper detectors, enabling users to monitor the environment and

the operating parameters of the design. The user can respond to the events that are determined to be out-of-scope

for proper operation. Tamper flags indicate that a tamper event has occurred and are available as signals to the

FPGA fabric for users to process and respond. The following is a partial list of tamper detectors:

• Clock glitch detectors

• Clock frequency detectors

• Voltage monitor detectors

• Temperature sensor

• JTAG active detector

• Mesh active detector

8.1.2

Tamper Responses

After processing a detected event, the user can perform one of the following actions.

• Disable I/Os—configurable on a per I/O basis

• Security lockdown

• Reset

• Zeroize
