The DS28E50 secure authenticator combines FIPS 202-compliant secure hash algorithm (SHA-3) challenge and response authentication with Analog Devices' patented ChipDNA™ technology, a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. The ChipDNA implementation utilizes the random variation of semiconductor device characteristics that naturally occur during wafer fabrication. The ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. Attempts to probe or observe ChipDNA operation modifies the underlying circuit characteristics thus preventing discovery of the unique value used by the chip cryptographic functions. The DS28E50 utilizes the ChipDNA output as key content to cryptographically secure all device-stored data. With ChipDNA capability, the device provides a core set of cryptographic tools derived from integrated blocks including a SHA-3 engine, a FIPS/NIST -compliant true random number generator (TRNG), 2Kb of secured EEPROM, a decrement-only counter and a unique 64-bit ROM identification number (ROM ID). 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 DS28E50 communicates over the single-contact 1-Wire® bus at both standard and overdrive speeds. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.
