External Provisioning/Programming Powered by Secure Thingz
We are surrounded by a myriad of Internet of Things (IoT) devices that are connected through a variety of infrastructures. This makes them more vulnerable to attacks than ever before. As the threat level continues to increase, embedded developers need to prioritize the implementation of security in their IoT applications. One approach used to secure applications is to develop/design secrets or keys that create a unique secure identity for each device. These keys are programmed/provisioned into a secure location on a microcontroller (MCU) by a secure programming provider.
To simplify the implementation of security in your product, Microchip has partnered with Secure Thingz to enable the SAM L11 family of MCUs to be provisioned at a secure external programming center. The external programming center will provide you with a provisioning kit that includes a very simple graphical software tool to enable you to securely encrypt your cryptographic keys and firmware to secure the application. After you complete the provisioning kit, the programming center will then securely provision the SAM L11 MCUs to create a secure identity that can be used as a foundation for securing your application. This identity can be used for applications such as IP protection, cloud attestation, supply chain management, secure updates and more.
What Does the Combination of a SAM L11 MCU and Secure Deploy Offer?
As this diagram illustrates, you will follow these two basic steps:
- Design/development of keys and certificates: Personalize your keys and certificates using the Secure Wrapping Tool that comes with the provisioning kit provided by your selected programming partner. The basic framework is securely encrypted, signed and then sent to the programming facility.
- Secure programming: The secure programming facility will receive your key framework and will securely provision the blank SAM L11 MCUs with your keys and use the input from the Secure Wrapping Tool (part of the provisioning kit) to securely provision keys/certificates into the SAM L11. Even if you use an unsecured link to send the file to the programming facility, this file can only be decrypted by the Hardware Security Module (HSM) at the programmer partner’s facility. After the keys and application are programmed into the SAM L11 MCUs, the debug access levels are set to ensure that the keys cannot be hacked by most typical digital/network attacks.
