Custom Part Manufacturing Service (CPMS)

Customize Your Wireless Hardware and MCUs with Advanced Security and Unique Certificates

Building an IoT device was easy in the past: developing code, flashing it on a chip, and manufacturing. Today, security is the ultimate challenge for IoT device makers. Your IoT device faces severe security threats throughout its entire supply chain, starting at the beginning of the outsourced manufacturing process.

New IoT Challenges

Product Counterfeiting

Outsourced manufacturing imposes various security risks at your IoT products – cloning, overproduction, and counterfeiting. Unencrypted software is subject to IP theft, and tampering is a threat throughout the supply chain.

“Zero Trust” Security Paradigm

No IoT device is trusted to pair with other devices or join an ecosystem such as AWS, Matter, and Wi-SUN any longer without a unique identity and secure authentication. Soon unauthenticated IoT devices cannot generate revenue!  

Regulation and Legislation

US and European authorities are responding to the increasing security threat with laws mandating IoT companies implement better security. Soon IoT devices must only run authenticated code. Only secure interfaces and ports are allowed. Secure software OTA update and a unique device ID become mandatory.

What is CPMS?

Custom Part Manufacturing Service (CPMS) allows you to customize Silicon Labs hardware – wireless SoCs, modules, MCUs – at the factory. The CPMS self-service web portal guides you through the customization process and its various customizable features and settings. You can place orders for customized test and production units to our factories securely via the CPMS portal.

Unlike traditional flash programming, CPMS is a secure provisioning service that enables you to customize your chips with several highly advanced features – these can include: secure boot, secure debug, encrypted OTA, public, private and secret keys, secure identity certificates, and more.

The custom features, identities and certificates are injected on the hardware securely, quickly, and cost-efficiently at the world’s safest place, the Silicon Labs factories.

 

Why CPMS?

Securing an IoT device is a highly complicated and costly process - you must generate public and private keys for secure boot and secure debug, sign code with a private key, store all the private keys in an HSM, place the public keys for secure boot and secure debug in one-time-programmable (OTP) memory, flip OTP bits for secure boot and secure debug, and flash the encrypted code and identity certificates within the hardware.

CPMS streamlines the programming part of this process for you. Even the most advanced security features, certificates, and identities can be programmed in a secure, fast, and cost-efficient way at the Silicon Labs factories.

 

Benefits

Key Features

Unique Part Number

Program your chips with a unique part number to track shipments to avoid overproduction and over-pricing. With the custom part numbers, you can know exactly how many parts your contract manufacturers order from Silicon Labs. 

Secret Keys

Inject custom public and private keys and other custom secret keys on the chips during manufacturing – safeguard your products right from the beginning of their lifecycle. 

Secure Bootloader

Pre-flash a secure bootloader of your choice on the chips to encrypt your software Intellectual Property (IP) during contract manufacturing. Safeguard your competitive edge in the market.  

Tamper Detection

Set up the right tamper detection features on your hardware in manufacturing. CPMS helps to navigate the countless alternative settings to protect your products against the most sophisticated tampering attacks. 

Debug Port

Configure the debug port to one of the three possible states securely before the chips leave the factory. 1. Standard 2. Secure Lock (can be unlocked with a secure debug token)
3. Permanent Lock

Application Software

Pre-flash your application software already in Silicon Labs chip manufacturing securely, and cost-efficiently without delaying your time to market at third parties. 

Custom Markings

Customize markings on the hardware to hide the exact technology used in your products to hide competitive advantages.

Custom Certificates

Program custom certificates on your chips at the Silicon Labs factories. Custom certificates can be used to authenticate (attestation) your devices with IoT cloud services, ecosystems (AWS, Matter, Wi-SUN) and smartphone applications.
