UNIT ID is a crypto coprocessor with hardware-based secure key storage, integrated with ATECC608B hardware cryptographic chip, using I2C communication interface. The chip has a built-in 10Kb EEPROM for storing keys, certificates, data, consumption records and security configurations. The configuration can be locked to prevent changes by restricting access to memory areas
Each ATECC608B comes with a guaranteed unique 72-bit serial number and includes several security features to prevent attacks on the device itself, or logical attacks on data transferred between devices.
Supporting Trust&GO platform (pre-built universal certificate for TLS-based network security authentication, such as: AWS-IoT, Azure, Google and other cloud platforms to verify registration), The internal certificate of the encryption chip can be obtained directly through the tool to complete the automatic registration without private key exposure.
This pre-provisioned Trust&GO secure element supports 'Microchip Trust Platform' only. For more details, please refer to below link. https://www.microchip.com/en-us/product/ATECC608B-TNGTLS
