Pre-Configured Secure Elements to Support the Most Common Authentication Use Cases


If you find yourself on this page, you’ve most likely already reviewed the features of the Trust&GO platform and have determined that you need a more flexible option to implement secure elements in your design. With our TrustFLEX platform, you can order a variety of secure elements with a pre-established locked configuration that supports the most common authentication use cases. 

Choose From These TrustFLEX Use Cases


  • Wireless Power Consortium (WPC) Qi® 1.3 wireless power charging authentication
  • Certificate authentication for any Public Key Infrastructure (PKI) or cloud platform
  • Token authentication
  • Secure boot (with key attestation)
  • Over-the-Air (OTA) verification
  • Firmware IP protection
  • Message encryption
  • Public and private key attestation
  • Private key rotation for device management
  • I/O protection key
  • Host accessory authentication
  • Device acessory authentication 
  • Host disposable authentication 
  • Device disposable authentication 

If the TrustFLEX use cases do not meet the requirements of your authentication model, please look at our TrustCUSTOM platform.

Ready to Get Started With TrustFLEX?


Step 1: Download the Trust Platform Design Suite, available for Windows® and macOS®, to prototype with your secure element.

Step 2: Buy the development kit of your choice, then prototype and integrate your application code in the microcontroller.

Step 3: Once the C code is working in your embedded application, you are ready to create the configuration file using the TrustFLEX configurator that is available in the Design Suite. After the configuration file is finalized, submit a support ticket to obtain your encryption key. Encrypt the configuration file using the provided utility, load it in the support ticket and you will receive provisioned validation devices by our Hardware Secure Module (HSM) equipped factories.

Title Description
How to Use Microsoft® Azure® RTOS and the ATECC608 TrustFLEX Secure Element In this blog you can read about how to implement a secure boot and Transport Layer Security (TLS) mutual authentication for your Internet of Things (IoT) device.
How Transport Layer Security (TLS) and Secure Elements Work In this blog you can learn about the importance of TLS and the embedded security pillars as encryption is weak without robust secure key storage to protect the private key.
Asymmetric Authentication Use Case Example The purpose of authentication is to prevent cloning and counterfeiting and to ensure that an object is genuine and authorized to connect to a product. In this use case example, find out how to authenticate an object, such as an accessory, peripheral, battery or cartridge, that is typically removable and replaceable by the consumer.
Secure Firmware Download Use Case Example In this use case example, you will see a demonstration of the authentication of a firmware update. The example uses asymmetric cryptography to establish a chain of trust to validate the update.
Securing Cloud-Connected Devices with Google Cloud IoT and Microchip This blog article written by Google discusses how the ATECC608B secure element strengthens authentication between IoT Core and IoT hardware.
Symmetric Authentication Use Case Example The purpose of authentication is to prevent cloning and counterfeiting and to ensure that an object is genuine and authorized to connect to a product. In this use case example, find out how to authenticate an object, such as an accessory, peripheral, battery or cartridge, that is typically removable and replaceable by the consumer.
Symmetric Authentication with a Non-Secure MCU Use Case Example In this use case example, you will learn how to authenticate an object using one-way symmetric authentication, which avoids the need for an Internet connection and white (or black) list. A white list is a lookup table for identifying approved units and a blacklist is a lookup table for identifying non-approved units.

General Questions:

Q: How can I get started with the Trust Platform?
A:
 Use the “Let Us Guide You to the Right Option” on the Trust Platform page, which will help you take the first step. You will find additional information about getting started with Trust&GOTrustFLEX and TrustCUSTOM on their pages.

Q: I am a distribution partner. How do I enroll in the Trust Platform program?
A:
 Contact your local Microchip sales office to request assistance with joining the program.

Trust&GO Questions:

Q: Do I need to contact Microchip to provision my Trust&GO secure element?

A: No. When you buy the device, it is already provisioned with keys and certificates specific to the use case you have selected that are locked inside the device. Trust&GO cannot be altered and is intended to be used as is.

Q: Where can I obtain the public keys and certificates for my Trust&GO device?
A: Log into your customer account at the ecommerce website where you purchased the device after device shipment, and you should be able to download a manifest file containing all the necessary public keys and certificates. Contact the vendor if you have any trouble finding this file.

TrustFLEX Questions:

Q: Do I need to contact Microchip to provision my TrustFLEX secure elements?  
A:
 Yes. When you buy the device, it comes pre-configured with your selected use case(s). By default, the TrustFLEX device also come with keys and generic certificates for thumbprint authentication that are overwritable internally if you have not already locked them using the lock bit. While the configuration cannot be altered, the default credentials can be changed if you have not already locked them. If you decide to use the default credentials, you will have to lock them after receiving the device. If you don’t want to use the default credentials, you can replace them with yours and then lock them. After you have made your decision, create the secret packet exchange, encrypt it and upload it into a support ticket on Microchip’s technical support portal. We will provision your devices and ship them according to your instructions.

Q: Where can I obtain the public keys and certificates for my TrustFLEX device when I use the default credentials?
A:
 Log into your customer account at the ecommerce website where you purchased the device after device shipment, and you should be able to download a manifest file containing all the necessary public keys and certificates. Contact the vendor if you have any trouble finding this file. WARNING: If you have overwritten the default credentials in your device, the manifest file will no longer be compatible with the device’s new credentials.

TrustCUSTOM Questions:

Q: Do I need to contact Microchip to provision my TrustCUSTOM secure element?
A:
 Yes. When you buy the device, it will be blank. You will need to use the TrustCUSTOM configurator, which is available under Non-Disclosure Agreement (NDA) to define the configuration, create the secret packet exchange, encrypt it and upload it into a support ticket on Microchip’s technical support portal. We will provision your devices and ship them according to your instructions.

Q: Where can I obtain the secret packet exchange for my TrustCUSTOM device?
A:
 This utility is only available through a Non-Disclosure Agreement (NDA). Contact your local Microchip sales office or distributor to request it.

Q: Where can I get the full data sheet for my TrustCUSTOM device?
A:
 This document is only available through a Non-Discloser Agreement (NDA). Contact your local Microchip sales office or distributor to request it.
