Analog Devices / Maxim Integrated DS28E84 DeepCover 1-Wire Authenticator
Analog Devices DS28E84 DeepCover 1-Wire Authenticator is a radiation-resistant secure authenticator with a core set of cryptographic tools. Security functions are derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256). The device integrates a FIPS-compatible true random number generator (TRNG). Also incorporated is 10Kb of secured OTP, 15Kb of FRAM, one configurable GPIO, and a unique 64-bit ROM identification number (ROM ID).
