Description
Description Unit ID is an encryption coprocessor with hardware-based secure key storage, integrating the ATECC608B hardware encryption chip and using the I2C communication interface. The chip has a built-in 10Kb EEPROM, which can be used to store keys, certificates, data, consumption records, and security configurations. By restricting access policies to memory areas, the configuration can be locked to prevent changes. Each ATECC608B comes with a guaranteed unique 72-bit serial number and includes multiple security features to prevent physical attacks on the device itself or logical attacks on data transmitted between devices. Supports the Trust&GO platform (pre-configured with universal certificates, suitable for TLS-based network security authentication, such as AWS-IoT, Azure, Google, and other cloud platform verification registrations). The internal certificate of the encryption chip can be directly obtained through tools to complete automatic registration without exposing the private key. Trust&GO The pre-configured Trust&GO security element only supports the "Microchip Trust Platform".
