DeepCover Secure ECDSA Bidirectional

Authenticator with ChipDNA PUF Protection

Design Resource Overview

Detailed Description

Operation of the DS28E39 involves use of device EEPROM

and execution of device function commands. The following

provides an overview including the decrement counter.

Refer to the DS28E39 Security User Guide for details.

The DS28E39 integrates the Maxim ChipDNA PUF

to protect all device stored data from invasive dis-

covery. Optionally, under user control, the ChipDNA

output can also be used as the ECC-P256 private

key. In addition to the ChipDNA circuit and ECC-P256

engines for signatures, the device integrates a FIPS/

NIST-compliant TRNG, 2Kb EEPROM for user mem-

ory, ECC key set, control registers, and certificates.

One user page can optionally be designated as a

decrement-only counter. The device operates from a

1-Wire interface with external parasitic supply by way of

Memory

and/or general-purpose, user-programmable memory.

Depending on the memory space, there are either default

or user-programmable options to set protection modes.
