DS28E36 DeepCover® Secure Authenticator

Analog Devices DS28E36 DeepCover® Secure Authenticator provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services offered by the hardware-implemented crypto engines, the device incorporates a FIPS/NIST true random number generator (RNG), 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). This unique ROM ID is used as a fundamental input parameter for cryptographic operations and as an electronic serial number within the application. The Analog Devices DS28E36 DeepCover Secure Authenticator communicates over the single-contact 1-Wire^® bus at overdrive speed. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multi-device 1-Wire network.
