Secure 4 click PID MIKROE-2829 Weight 24 g Secure 4 click includes the ATECC608A, a secure CryptoAuthentication device from Microchip, which is equipped with an EEPROM array which can be used for storing of up to 16 keys, certificates, consumption logging, security configurations and other types of secure data. Access to the various sections of memory can be restricted in several different ways and then the configuration can be locked permanently, to prevent changes. The ATECC608A equipped on this click board , supports the I2C interface with a flexible command set, that allows use in various security applications, including Network/IoT Node Endpoint Security, Secure Boot, Small Message Encryption, Key Generation for Software Download, Ecosystem control, Anti Counterfeiting and similar.

It can also generate random private keys and random numbers, which can be used as a part of the crypto protocol.
