Add Custom Key Storage to Any Embedded Design


If you have already reviewed our& Trust&GO and TrustFLEX options and determined that you need more customization for your secure element or Platform Root of Trust device, then the TrustCUSTOM platform is the best choice. It enables you to implement and fully customize secure key storage and other firmware security use cases in your design. You will start with a blank ATECC608B-TCSM, ATSHA204A-TCSM, or CEC173x-TCSM device and use our tools to configure it to meet your specific security authentication requirements. At the end of the process, you will be able to order your devices and securely provision them by leveraging our Hardware Secure Modules (HSMs) that are installed in our secure factories.
