DeepCover Secure Authenticator
General Description
The DS28C36 is a secure authenticator that provides a
core set of cryptographic tools derived from integrated
asymmetric (ECC-P256) and symmetric (SHA-256) secu-
rity functions. In addition to the security services provided
by the hardware implemented crypto engines, the device
integrates a FIPS/NIST true random number genera-
tor (RNG), 8Kb of secured EEPROM, a decrement-only
counter, two pins of 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
compliant ECDSA signature generation and verification
to support a bidirectional asymmetric key authentication
model. The SHA-256 secret-key capabilities are compli-
ant with FIPS 180 and are flexibly used either in conjunc-
tion with ECDSA operations or independently for multiple
HMAC functions.
Two GPIO pins can be independently 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.
