Cyber Security is the #1 Concern for Connected Devices on the Network Edge
It is not enough for today's demanding applications to meet the functional requirements of their design—they must do so in a secured way. Security starts during silicon manufacturing and continues through system deployment and operations. Microsemi's PolarFire FPGAs represent the industry's most advanced secure programmable FPGAs.

Are SRAM-based FPGAs Secure?
SRAM-based FPGA's lack the key capabilities required to create a trusted and secure hardware platform for a secure embedded system making them vulnerable to cloning, copying, and reverse engineering. Sensitive customer data can be attacked and embedded systems compromised.
Microsemi FPGAs Create the Secure Foundation for Your System
Secure hardware is used to create a secure hardware Root of Trust. A hardware Root of Trust is an immutable and trusted starting point from which security can be extended to other parts of the system. Without this secure foundation your system can't be protected. A secure hardware Root of Trust must include the following capabilities:
- Licensed, Patented DPA Protection
- Protects design IP from copying and reverse engineering
- Built-in Certified Security Functions
- True Random Number Generator, Physically Unclonable Function (PUF), Elliptical Curve Cryptography (ECC), AES, SHA, HMAC
- Tamper Detectors with Counter Measures
- Supply Chain Assurance that the FPGA is Authentic
- Factory Hardware Secure Module (HSM) Flow for Secure Key Injection
- Factory Key Database Generation
- Signed Device Digital Certificate
Licensed, Patented DPA Protection Counters Side Channel Attacks
Side-Channel Analysis attacks use information that 'leaks' from electronic systems to determine otherwise secret information.
- Like a safecracker listening to tumblers in a lock, side-channel analysis uses changes in operating current and timing information to indirectly determine on-chip secret keys.
- Differential Power Analysis uses statistical results of many measurements to find secret keys used in cryptographic functions.
- Without DPA resistance security keys are vulnerable and security systems can be completely bypassed.
- Microsemi has licensed from CRI, a division of Rambus, their DPA resistant patent portfolio to protect key operations from DPA sice channel attacks.

Built-in Certified Security Functions
Once the on-chip security keys and configuration bit streams are protected from DPA it is important to support the cryptographic functions needed to extend security and create a hardware Root of Trust. Key cryptographic functions must include:
- True Random Number Generation- used by many cryptographic standards
- Physically Uncloneable Function- used to create device unique security keys known only to the device
- Hardware Acceleration for Security Standards
- AES, SHA, HMAC and ECC
View the above video to see how security services in Microsemi SmartFusion2 SoC FPGAs and IGLOO2 FPGAs are used to support common security standards.
If your Supply Chain Isn't Secure, How Can Your System Be?
Microsemi secure manufacturing flow:
- Inject device unique keys with FIPS Hardware Security Modules (HSMs)
- Inject device unique signed X.509 digital certificate proving authenticity of device purchased
- Secure Derived Key Database generation for customer Managed HSM flow
View this video to see how a secure supply chain is protected when using SmartFusion2 SoC FPGAs and IGLOO2 FPGAs- beginning with secrets 'baked' into the wafer, through wafer test, assembly and binning, all the way to sales via the distribution channel. Hardware security modules, secure key storage and X.509 certificates all contribute to the Microsemi secure manufacturing flow that protects your supply chain.
Protect Your Valuable Design IP From Copying and Reverse Engineering
Microsemi FPGAs leverage built-in design security features to protect your valuable design IP:

Secure Configuration Bit Streams with DPA Protection
Microsemi FPGAs use encrypted, DPA protected and authenticated bit streams to prevent copying and cloning.
- Only bitstreams encrypted with the key matching the key in the device will be programmed into that device
- Hardware security modules allow for secure production programming and accounting of programmed devices
Tamper Protection, Zeroization and Security Key Protection
Protecting Your Design also requires features to detect unauthorized access to critical on-chip data.
- On chip built in tamper detectors
- User configurable tamper macro with EnforcIT IP for tamper response
- Zeroize the device in response to a tamper event
- Disable JTAG, ETM
- Disable Verify

Secure Production Flow Programming
Hardware Security Modules (HSMs), managed by a secure production center, create a secure environment using:
- Cryptographically Secure Build Tickets - build only N systems
- Certificate of Conformance - prove only N number of devices were built
Use Microsemi SmartFusion2 SoC FPGA or IGLOO2 FPGA devices in your next design to automatically protect your valuable design IP, sensitive data and embedded system. Use the Microsemi FlashPro5 programmer with Microsemi Libero SoC development tool suite to protect your valuable design IP no matter where they are programmed.

Tamper Prevention and Detection
Tamper prevention and detection block attacks that can extract secret data or change the state of the device, and provide an alarm signal if tampering is suspected. Some of the techniques used on Microsemi FPGAs include:
- Security lock modification
- Mesh open/short detection
- Clock tamper monitor
- Countermeasures for passive and active side channel attacks
- Detection of attempted programming port access and authentication failures
- Keys, passcodes (in NVM), and other data-at-rest (in ROM and RAM) protected cryptographically
- Digests on NVM and ROM to detect attacks on memory, keys or settings
- Microsemi offers the EnforceIT Security Monitor IP block that can flexibly process tamper flags, allow time for communication with a host system if desired, and trigger built-in or your own custom chip or system-level tamper penalties.
Tamper Penalties and Zeroization
Once tampering is detected it is useful to apply a penalty. It is common to use escalating penalties if tampering occurs too often or is too severe. A severe penalty, zeroization, can be applied to erase part or all of a device, even returning it to an unprogrammed state. Microsemi FPGAs can implement a variety of built-in penalties, such as:
- Resetting the device- so it reboots in a known, safe state
- Disabling I/O- to prevent loss of secrets
- Placing all security options in to their most secure state
- Zeroizing on-chip memory
- Erasing FPGA configuration NVM and MSS embedded NVM
- Erasing MSS SRAM, and fabric block RAMs & registers
- Erasing all crypto-variable storage incl. (optionally) the Factory Keys
- Eliminating any remnant traces of the non-volatile configuration
- Verifying all NVM and SRAM is in a known state, and
- Supplying a cryptographic proof of success

Pass-through License for CRI Patented DPA Protection
Microsemi has obtained a license from Cryptography Research, Inc. (CRI, now a division of Rambus) for the DPA patent portfolio, consisting of more than fifty patents. The pass through license:
- Extends a sub-license to customers who purchase selected Microsemi FPGA devices. The purchaser can then use any of CRI's patented DPA-mitigation techniques to protect their end-application from side-channel attacks. The protection techniques can be incorporated in the user's logic implemented in the FPGA fabric or in the user's firmware executing on a hard or soft microcontroller, in the licensed Microsemi FPGA. No additional paperwork paperwork is required of the purchaser of these devices to use this license.
- Users of Microsemi's DPA resistant Secure Boot Reference design have also been granted a pass through license to a target processor for implementing a secure boot function in conjunction with Microsemi FPGAs or SoC FPGAs. The user has only to sign an Eligibility Certification Form to be able to use CRI’s patented DPA mitigation techniques in their target processor’s boot-loader with these Microsemi FPGAs.
