Wire up secure element (crypt chip) to existing PCB
Budget: $250 – $750 USD
Hello,
We have an existing PCB which utilizes an ESP8266 chip with firmware written in C++ (Arduino) which works well. However, we are productionizing our consumer electronics product and need to add a secure element (aka crypto chip - ATECC608B) to the PCB.
Please find the data sheet for the secure element (ATECC608B) that we are planning adding to our existing circuit board.
The workflow our system will use is to simply use portions of their ECC key as both the IV and CBC AES 256 bit encryption keys to encrypt/decrypt the end user Wi-Fi credentials which will be saved in our ESP8266 EEPROM device. There is a lot of additional functionality offered by the secure element which we may use in subsequent versions of our product; but for now this is it.
Please take a look at the attached data sheet and validate that you have enough information to connect it to our PCB before submitting to our project. More information on the Microchip secure data element that we are using can be found here: https://www.microchip.com/en-us/product/ATECC608B-TNGTLS?_ga=2.39661155.1126574565.1698865172-1733081797.1698865172#
Thanks in advance for your consideration.
