DS28E30X+U

DS28E30X+U is a 1-wire ECDSA secure authenticator. It provides a highly secure and easily deployed turnkey authentication solution based on the FIPS-186 ECDSA standard. It combines ECDSA challenge and response authentication with secured EEPROM for the storage of the keys and user data. This device provides a core set of cryptographic tools derived from integrated blocks including an asymmetric hardware engine, a true random number generator (TRNG), 3Kb of secure EEPROM, a decrement-only counter, and a unique 64-bit ROM identification number (ROM ID). The ECC public/private key capabilities operate from the NIST-defined P-256 curve to provide a FIPS 186-compliant ECDSA signature generation function to support a bidirectional asymmetric key authentication model. It is used in applications such as battery authentication and charge cycle tracking, medical tools/accessories authentication and calibration, accessory, and peripheral secure authentication.
