DeepCover Secure SHA-3 Authenticator with
ChipDNA PUF Protection
DS28E50
General Description
Benefits and Features
The DS28E50 secure authenticator combines FIPS
202-compliant secure hash algorithm (SHA-3) challenge
and response authentication with Analog Devices' patent-
ed ChipDNA™ technology, a physically unclonable func-
tion (PUF) to provide a cost-effective solution with the ul-
timate protection against security attacks. The ChipDNA
implementation utilizes the random variation of semicon-
ductor 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 char-
acteristics thus preventing discovery of the unique value
used by the chip cryptographic functions. The DS28E50
utilizes the ChipDNA output as key content to crypto-
graphically 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 en-
gine, a FIPS/NIST-compliant true random number gener-
ator (TRNG), 2Kb of secured EEPROM, a decrement-on-
ly 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 communicates over the single-contact 1-Wire
bus at both standard and overdrive speeds. The commu-
nication follows the 1-Wire protocol with the ROM ID act-
ing as node address in the case of a multidevice 1-Wire
network.
