DS28C40G/V+U Authentication Chip 10-TDFN (3x4) Surface Mount
Exposed PadGeneral DescriptionThe DS28C40 is a secure authenticator that 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 provided by the hardware implemented crypto
engines, the device integrates a FIPS/NIST true random number
generator (TRNG), 6kb of one-time programmable (OTP) memory for
user data, keys and certificates, 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 186-4 compliant ECDSA signature generation
and verification to support a bidirectional asymmetric key
authentication model. The SHA-256 secret-key capabilities are
compliant with FIPS 180 and are flexibly used either 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. 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 active die
shield, encrypted storage of keys, and algorithmic methods. Applications● Automotive Secure Authentication● Identification and Calibration Automotive Parts/Tools/
