Resumen del producto
DS2478ATB/VY+ is a DeepCover® secure ECDSA and HMAC SHA-256 coprocessor. The coprocessor can compute any required HMACs or ECDSA signatures to do any operation on the DS28E40 or DS28C40. The DS2478 provides a core set of cryptographic tools derived from integrated asymmetric (ECC P-256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware-implemented crypto engines, this device integrates a FIPS/NIST true random number generator (TRNG), 6Kb of secured one-time-programmable (OTP) memory, one configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). It is used in applications such as automotive secure authentication, identification and calibration automotive of parts/, tools/accessories, IoT node crypto-protection, secure authentication of accessories and peripherals, secure storage of cryptographic keys for a host controller, secure boot or download of firmware and/or system parameters.
