DS2478 DeepCover Automotive Secure Coprocessor
●The DS2478 is a DeepCover® secure ECDSA and HMAC SHA-256 coprocessor companion to the DS28E40 or DS28C40. 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 hard-ware implemented crypto engines, the 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).
●The ECC public/private key capabilities operate from the NIST-defined P-256 curve and include FIPS 186-compli-ant ECDSA signature generation and verification to sup-port a bidirectional asymmetric key authentication model. The SHA-256 secret-key capabilities are compliant with FIPS 180 and are flexibly used in conjunction with ECDSA operations or independently for multiple HMAC functions.
●The GPIO pin can be operated under command control and include configurability supporting authenticated and nonauthenticated operation including an ECDSA-based crypto-robust mode to support secure-boot of a host processor. This secure-boot method can also be used to enable the coprocessor functions.
●DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced security to provide the most secure key storage possible. To protect against device-level security attacks, invasive and noninvasive countermeasures are implemented, including an active die shield, encrypted storage of keys, and algorithmic meth-ods.
