Matter production, simplified.

Silicon Labs is the only IoT embedded solution provider offering a Custom Part
Manufacturing Service (CPMS) to device makers. This secure provisioning service
allows IoT device makers to order customized hardware straight from the factory via
the CPMS web portal. CPMS removes the numerous complexities, time, and expense ofcustom provisioning Matter devices at scale.

Silicon Labs has partnered with Kudelski Security toprovide scalable access to Device Attestation
Certificates (DACs) for your Matter devices. Kudelski
has 30+ years of experience securely provisioning
more than 500 million devices. Rest assured that yoursecrets are stored in HSMs both on and offline toprovide maximum security for your secret key material.

What is Matter?

Matter is an open-source connectivity standard to connect smart home and Internet ofThings (IoT) devices securely with one another. The protocol was created by theConnectivity Standards Alliance (CSA) and is supported by companies such as Amazon,Apple, Google, Samsung, and Zigbee Alliance members. Matter includes securityfeatures designed to protect devices from cyber attacks.

How do I get started with Silicon Labs & Matter?
In order to certify your Matter devices, your organization will need to become a member of the Connectivity Standards
Alliance (CSA). Silicon Labs provides integrated tooling through Simplicity Studio to help get you moving fast. We provide anumber of Matter application examples on Github that you can start with. If you decide to simplify your path to production,
we provide integrated production services through our CPMS portal that can work in conjunction with Simplicity Studio toget you setup in CPMS. You will also need to setup and account with our preferred Matter CA, Kudelski in order to get theDACs that will be needed for your Matter devices.

We partner with Kudelski as aCA to provide the DACs
needed for your devices. Set
up an account with Kudelski
to create and securely store
your PAI private key material.

Once development iscompleted, you will need tocertify your device. This
happens through a CSA
approved test facility. Onceapproved, CSA will issue aCertification Declaration or(CD).

How do I get started with CPMS & Matter?
CPMS solves the very difficult problem of “How in the world do I get unique certificates in every production device on themanufacturing line and do this securely?”. Rather than spending months solving this workflow yourself and trying to bend
your contract manufacturer to do your very complicated bidding, CPMS simply needs to know a few configuration values
and your products will be off to the races. If your team uses Simplicty Studio, you can simply export a JSON file to instruct
CPMS about your product. Your product will hit the market faster, more securely, and give you that edge over yourcompetitors that are attempting to accomplish this themselves.

Happy Customer

Once certified, bring yourfirmware and Certification
Declaration (CD) to CPMS.
We work with our partner
Kudelski to properly secure
the device and provide test
samples. You will also be
issued an Order-able Part
Number (OPN).

CPMS interacts with Kudelski
through our Secure Vault
Services to generate thesigned DACs needed toidentify your device on theMatter network. This is done
behind the scenes with noaction needed by you.

Silicon Labs securely
manufactures your Matterdevices based on the OPN
provided by CPMS. Unique
DACs are injected into eachdevice at the time ofmanufacture. Your Matterdevices are manufactured
and ready to ship.

The final step is the unboxingof your Matter device andmarveling at what youcreated. 

The only action left is tobecome a leader in theMatter ecosystem.

CSA Membership
Become a member of CSA (Connectivity Standards Alliance, formerly theZigbee Alliance) to take advantage of device certification and othermember services. You will also need to register for a Vendor ID (VID)
through CSA once you are a member. This VID will be used to identify
valid vendors through the Distributed Compliance Ledger (DCL).

Manufacturing Service (CPMS) also to simplify your production
experience once your are certified and ready to hit the market.

Kudelski account
As you get closer to production and start to think about getting your
Matter device to market, you will need to start considering how you will
provision your devices at scale with a proper Certificate Authority (CA)to sign and issue your Device Attestation Certificates (DAC).

Silicon Labs partners with Kudelski Security to sign and issue DACs
signed with a valid PAA and PAI by Kudelski. This process is integrated
into our manufacturing facilities to make this a seamless process saving
your organization countless hours trying to develop processes togenerate these unique DACs and get them into your parts at scale atyour manufacturing facility or CM.

Getting ready for production.

4Device Certification
Your team has been working diligently, developing the next great MatterIoT device and you’re ready to go to market. Your next step is to get yourdevice certified through a CSA approved testing facility. There are anumber of different certification vendors that will test your device toensure that it properly adheres to the Matter specification.

The end result of the certification process is a Certification Declaration(CD) which is issued by CSA once your device passes. The CD will beadded to the device programming and used during commissioning toattest that the device is certified.

Why certify? https://csa-iot.org/certification/why-certify/5CPMS Configuration
Your team has done all of the hard work in creating a Matter device.
You’ve certified that device through a CSA testing facility. Now what?
How do I get these manufactured at scale with unique DACs in eachone? 

This is where CPMS excels. CPMS allows you to customize your device
even further, including the ability to add the Matter ecosystem to yourdevice. Simply provide the necessary inputs, or you can create a data
model through our development tools that will pre-fill these fields for you
based on your device. CPMS will work with Kudelski behind the scenes
to generate the DACs and provision these to your samples.

6DAC Creation
When your sample order is submitted, CPMS gets to work ordering theDACs for your device through our Secure Vault Services (SVS). Theinputs added to CPMS such as your VID, PID, and other inputs are sent
to Kudelski to create the unique DACs for your device and are sent backto Silicon Labs. One important note when creating your account withKudelski, you will need to add Silicon Labs as a requestor and receiver ofDACs for this PAI so that this process can happen seamlessly.

Once Silicon Labs has the DACs, the manufacturing process can begin.
The DACs are placed into the manufacturing process to generate yoursample order.

Manufacturing
Silicon Labs securely manufactures your Matter devices based on theOPN provided by CPMS. The signed DACs that we received from
Kudelski are injected into each device at the time of manufacture. Your
Matter samples are manufactured and ready to ship back to you forapproval.

Once you have had time to validate that the samples are working to yoursatisfaction, return to CPMS to approve the samples (or you may reject
the samples if a problem exists). Once approved, you have an OPN fromSilicon Labs that can be order from any of our third-party distributors.

8Happy Customer
In the end, we hope that you had a positive experience with CPMS andyour Matter device. As always, Silicon Labs is ready to help support you
through this process. Setting up custom provisioning in a manufacturing
process is a daunting task. Our aim is to make this a seamless process
through our Custom Part Manufacturing Service so that you don’t haveto.

Thank you for your interest in manufacturing your Matterdevice with Silicon Labs.
