DS2478 DeepCover® Automotive Secure Coprocessor

Analog Devices DS2478 DeepCover^® Automotive Secure Coprocessor can compute any required HMACs or ECDSA signatures to do any operation on the DS28E40 or DS28C40 ICs. This coprocessor supports multiple asymmetric (ECC P-256) and symmetric (SHA-256) security functions for the DS28E40/DS28C40 ICs. In addition to the security services provided by the hardware-implemented ECC and SHA-256 engines, the device integrates a FIPS/NIST true random number generator (TRNG). The device also integrates 6Kb of secured OTP (3Kb user, 3Kb keys/secrets), one configurable GPIO pin, and a unique 64-bit ROM identification number (ROM ID).
