DeepCover Radiation-Resistant 1-Wire  
Authenticator  
DS28E83  
General Description  
Benefits and Features  
The DS28E83 is a radiation-resistant secure authenticator  
that 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, the device integrates a FIPS-compatible true ran-  
dom number generator (TRNG), 10Kb of secured OTP,  
one configurable GPIO, and a unique 64-bit ROM identifi-  
cation number (ROM ID).  
High Radiation Resistance Allows User-Programmable  
Manufacturing or Calibration Data Before Medical Steril-  
ization  
● Resistant up to 75kGy (kiloGray) of Radiation  
● One-Time-Programmable (OTP) 10kb of User Data,  
Keys, and Certificates  
ECC P-256 Compute Engine  
● FIPS 186 ECDSA P-256 Signature and Verification  
● ECDH Key Exchange for Session Key Establishment  
● ECDSA Authenticated R/W of Configurable Memory  
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 either in conjunction with  
ECDSA operations or independently for multiple HMAC  
functions.  
SHA-256 Compute Engine  
● FIPS 180 MAC for Secure Download/Boot  
● FIPS 198 HMAC for Bidirectional Authentication and  
Optional GPIO Control  
SHA-256 OTP (One-Time Pad) Encrypted R/W of Config-  
urable Memory Through ECDH Established Key  
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.  
One GPIO Pin with Optional Authentication Control  
● Open-Drain, 4mA/0.4V  
● Optional SHA-256 or ECDSA Authenticated On/Off  
and State Read  
● Optional ECDSA Certificate to Set On/Off After  
Multiblock Hash for Secure Download  
®
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 meth-  
ods.  
TRNG with NIST SP 800-90B Compliant Entropy Source  
with Function to Read Out  
Optional Chip-Generated Pr/Pu Key Pairs for ECC Opera-  
tions or Secrets for SHA-256 Functions  
Unique and Unalterable Factory-Programmed 64-Bit Iden-  
tification Number (ROM ID)  
Applications  
● Medical Consumables Secure Authentication  
● Medical Tools/Accessories Identification and  
Calibration  
● Accessory and Peripheral Secure Authentication  
● Secure Storage of Cryptographic Keys for Host  
Controllers  
● Secure Boot or Download of Firmware and/or System  
Parameters  
● Optional Input Data Component to Crypto and Key  
Operations  
Advanced 1-Wire Protocol Minimizes Interface to Just Sin-  
gle Contact  
Operating Range: 3.3V ±10%, 0°C to +50°C  
±8kV HBM ESD Protection of 1-Wire IO Pin  
6-Pin TDFN and 2-Pin SFN
