DS28E39

DeepCover Secure ECDSA Bidirectional

Authenticator with ChipDNA PUF Protection

General Description

Beneﬁts and Features

● Robust Countermeasures Protect Against Security

The DS28E39 is an ECDSA public-key-based bidirec-

tional secure authenticator that incorporates Maxim’s

patented ChipDNA™ feature, a physically unclonable

function (PUF) to provide a cost-effective solution with

the ultimate protection against security attacks. Using 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 characteristics, preventing discovery

of the unique value used by the chip cryptographic func-

tions. The DS28E39 utilizes the ChipDNA output as key

content to cryptographically secure all device stored data

and optionally, under user control, as the private key for

the ECDSA signing operation. With ChipDNA capabil-

ity, the device provides a core set of cryptographic tools

derived from integrated blocks including an asymmetric

(ECC-P256) hardware 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 ECC public/

private key capabilities operate from the NIST-defined

P-256 curve to provide a FIPS 186-compliant ECDSA

signature generation function. 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 DS28E39 communicates over

the single-contact 1-Wire® bus at both standard and

overdrive speeds. The communication follows the 1-Wire

protocol with the ROM ID acting as node address in the

case of a multidevice 1-Wire network.
