DeepCover Radiation Resistant
1-Wire Authenticator
General Description
The DS28E83 is a radiation-resistant secure authentica-
tor 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-compatible true
random number genera­tor (TRNG), 10Kb of secured
OTP, 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-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 nonau-
thenticated 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
Medical Consumables Secure Authentication
