XINABOX LIMITED AH01

This xCHIP is a core encryption module which forms part of the Crypto module range, running a security algorithm based on SHA-256. It includes the ATECC508A from Atmel which is a secure CryptoAuthentication device, which is equipped with an EEPROM array that can be used for storing of up to 16 key, 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. Hardware restrictions on the ways in which keys are used or generated provide further defence against certain styles of attack. Access to the device is made through a standard I2C interface at speeds of up to 1Mb/s. Applications include IoT node security and ID, secure download and boot, ecosystem control, message security and anti-cloning.
