DS28C50

DeepCover® I C Secure SHA-3 Authenticator

with ChipDNA PUF Protection

General Description

Benefits and Features

The

DS28C50

secure

authenticator

combines

● Robust Countermeasures Protect Against Security

Attacks

FIPS202-compliant secure hash algorithm (SHA-3) chal-

lenge 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 out-

put value that is repeatable over time, temperature, and

operating voltage. Attempts to probe or observe ChipDNA

operation modifies the underlying circuit characteristics,

thus preventing discovery of the unique value used by the

chip cryptographic functions. The DS28C50 utilizes the

ChipDNA output as key content to cryptographically se-

cure 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 DS28C50 com-

• Patented Physically Unclonable Function Secures
