Connectivity - Microchip ATECC608B key takeaways

Microchip ATECC608B secure element key takeaways:

• Optimal level of protection for IoT designs (JIL rating high) against all known hardware and software attacks.
• Microchip ATECC608B is a cost-effective, flexible on-boarding with personalization service open to low volume.  
• This personalization service offers a unique part number per customer product, allowing for better control of the supply chain, and prevents overbuilding.
• It supports all major cloud vendors AWS, Azure and Avnet IoTConnect.
• Microchip Trust Platform v2 tool is a real game changer to easily program and prototype an ATECC608B secure element. Most use cases are very well documented with step-by-step tutorial and even videos.
• The device firmware remains entirely generic as credentials are loaded directly onto the personalized secure element, simplifying firmware design and firmware upgrade procedure.

Connectivity - Software network stack architecture

Main Focus for the stack implementation:

• Protect device identity using ATECC608. Certificates are injected in the SE using TPDSv2 (Avnet IoTConnect Custom PKI use case).
• FreeRTOS with minimalistic SW implementation.
• No PKCS11 involved, only mbedTLS.
• Network stack code size < 250kB.

Offload Crypto Operations to SE:

• Sign crypto operation is performed by ATECC.
  • MbedTLS perform sign operation against ATECC slot 0.
     
• Verify crypto operation is performed by ATECC but public keys are provided by host (ATECC memory limitation).
• ECDH is performed by ATECC in temp slot.
