DS28E50

DeepCover Secure SHA-3 Authenticator

with ChipDNA PUF Protection

General Description

Beneﬁts and Features

● Robust Countermeasures Protect Against Security

The DS28E50 secure authenticator combines FIPS202-

compliant secure hash algorithm (SHA-3) challenge

and response authentication with Maxim’s patented

ChipDNA™ technology, a physically unclonable function

(PUF) to provide a cost-effective solution with the ultimate

protection against security attacks. The ChipDNA imple-

mentation utilizes the random variation of semiconductor

device characteristics that naturally occur during wafer

fabrication. The ChipDNA circuit generates a unique

output value that is repeatable over time, temperature,

and operating voltage. Attempts to probe or observe

ChipDNA operation modifies the underlying circuit charac-

teristics thus preventing discovery of the unique value used

by the chip cryptographic functions. The DS28E50 utilizes

the ChipDNA output as key content to cryptographically

secure all device-stored data. With ChipDNA capability, the

device provides a core set of cryptographic tools derived

from integrated blocks including a SHA-3 engine, a FIPS/

NIST compliant true random number generator (TRNG),

2Kb of secured EEPROM, a decrement-only counter and

a unique 64-bit ROM identification number (ROM ID). The

unique ROM ID is used as a fundamental input parameter

for cryptographic operations and serves as an electronic

serial number within the application. The DS28E50 com-

municates over the single-contact 1-Wire® bus at both

standard and overdrive speeds. The communication fol-

lows the 1-Wire protocol with the ROM ID acting as node

address in the case of a multidevice 1-Wire network.
