6.3 TrustFLEX vs. Trust&GO

Trust&GO products have been defined for customers with low volumes that can use a secure off-the-shelf solution. The product’s simple onboarding procedure leverages Microchip’s secure manufacturing solution and infrastructure. By using this flow, customers do not have to create their own secure manufacturing environment.

However, at times customers may want to have more control over their security environment while still enjoying the simplicity of the Trust&GO product use. The TrustFLEX product was created for these customers. TrustFLEX products are still capable of implementing the use cases of the Trust&GO product but provide additional flexibility for some of the security keys and certificates.

Same locked configuration as that of the Trust&GO product.
Same data slot definition as that of the Trust&GO.
Ability to provision the customer’s public key into the device for Secure Boot implementation.
Ability to do Symmetric Key Authentication. Customers can securely provide their desired Symmetric Keys as part of the secure provisioning process.
Ability to customize certificate elements and link the certificate chain to the customer's desired PKI.
Option for either I²C or SWI interface devices.
