The DS28E54 secure authenticator combines FIPS 202- compliant secure hash algorithm (SHA-3) challenge and response authentication with secured electrically erasable programmable read-only memory (EEPROM).

The device provides a core set of cryptographic tools derived from integrated blocks, including an SHA-3 engine, 2.25Kbit of secured user EEPROM, a decrement-only counter, and a unique 64-bit ROM identification number (ROM ID), all while remaining reverse compatible to the DS2431/DS28E07.

The unique ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application.

The device communicates over the single-contact 1- Wire® bus.

The communication follows the 1-Wire protocol, with the ROM ID acting as the node address in the case of a multidevice 1-Wire network.
