Pre-provisioned IoT security solutions for any deployment size
Microchip’s has three tiers to its Trust Platform that deliver out-of-the-box pre-provisioned, pre-configured or fully customizable secure elements. The tiered approach allows developers to choose the solution that is correct for their own application.
The first tier is called Trust&GO and it provides zero-touch pre-provisioned secure elements with an MOQ down to 10 units. The credentials of the devices are pre-programmed, shipped and locked inside the ATECC608A for automated cloud or LoRaWAN authentication onboarding. Corresponding certificates and public keys are delivered in a “manifest” file, which is downloadable through Microchip’s e-commerce store and select distribution partners. The solution makes it easy to secure and manage edge devices without the overhead cost of third-party provisioning services or certificate authorities.
TrustFLEX is the second tier in Microchip’s new programme. It allows the customer to use a certificate authority of choice while gainng the benefits of pre-configured use cases, which include include baseline security measures such as Transport Layer Security (TLS) hardened authentication for connecting to any IP-based network using any certificate chain, LoRaWAN authentication, secure boot, OTA updates, IP protection, user data protection and key rotation. TrustFLEX will cut the time and complexity for those wishing to customizing devices without requiring customized part numbers.
For fully custom designs, TrustCUSTOM is the third tier in the programme. It provides customer-specific configuration capabilities and custom credential provisioning.
To simplify the process even further, Microchip and Amazon Web Services (AWS) have worked together to enable a simplified onboarding process into AWS IoT services for products using any tier of the Microchip Trust Platform.
The ATECC608A provides Common Criteria Joint Interpretation Library (JIL) “high”-rated secure key storage, giving confidence that devices implement industry-proven security practices and the highest level of secure key storage. Using hardware-based root of trust storage and cryptographic countermeasures, the device protects against the widest classes of known physical attacks. Microchip’s secure manufacturing facilities safely provision keys, ensuring that keys are never exposed to any party during provisioning or the lifetime of the device.
Development Tools
The ATECC608A can be paired with any microcontroller and microprocessor. For rapid prototyping of secure solutions, designers can use the Trust Platform Design Suite, which includes:
• A guided “use case tool”
• Executable Python tutorials running on Jupyter notebooks
• C code examples for each use case
• A “secret exchange” utility
• The Trust Platform hardware development kits
