DS28E40

Deep Cover Automotive 1-Wire Authenticator

General Description

Benefits and Features

The DS28E40 is a secure authenticator that provides a

core set of cryptographic tools derived from integrated

asymmetric (ECC-P256) and symmetric (SHA-256) secu-

rity functions. In addition to the security services provided

by the hardware-implemented cryptographic engines, the

device integrates a FIPS/NIST True Random Number

Generator (TRNG), 6Kb of One-Time Programmable

(OTP) memory for user data, keys and certificates, one

configurable General-Purpose Input/Output (GPIO), and a

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

● ECC-P256 Compute Engine

• FIPS 186 ECDSA P256 Signature and Verification

• ECDH Key Exchange for Session Key

Establishment

• ECDSA Authenticated R/W of Configurable Memory

● SHA-256 Compute Engine

• FIPS 198 HMAC for Bidirectional Authentication

● SHA-256 One-Time Pad Encrypted R/W of

Configurable Memory Through ECDH Established Key

● One GPIO Pin with Optional Authentication Control

• Open-Drain, 4mA/0.4V

The ECC public/private key capabilities operate from the

NIST-defined P-256 curve and include FIPS 186 compli-

ant ECDSA signature generation and verification to sup-

port a bidirectional asymmetric key authentication model.

The SHA-256 secret-key capabilities are compliant with

FIPS 180 and are usable flexibly either in conjunction with

ECDSA operations or independently for multiple Hash-

Based Message Authentication Code (HMAC) functions.

• Optional SHA-256 or ECDSA Authenticated On/Off

and State Read

• Optional ECDSA Certificate Verification to Set On/

Off after Multiblock Hash for Secure Boot

● TRNG with NIST SP 800-90B Compliant Entropy

Source with Function to Read Out

● Optional Chip-Generated Pr/Pu Key Pairs for ECC

Operations

● 6Kb of One-Time Programmable (OTP) for User Data,

Keys, and Certificates

● Unique and Unalterable Factory-Programmed 64-Bit

Identification Number (ROM ID)

The GPIO pin is operated under command control and is

configurable enabling support of authenticated and non-

authenticated operation. The GPIO-authenticated opera-

tion supports ECDSA-based crypto-robust mode, enabling

secure-boot of a host processor.

DeepCover embedded security solutions cloak sensitive

data under multiple layers of advanced security to provide

the most secure key storage possible. To protect against

device-level security attacks, including invasive and non-

invasive methods, countermeasures include active die

shield, encrypted storage of keys, and algorithmic meth-

ods.

• Optional Input Data Component to Crypto and Key

Operations

● Single-Contact, 1-Wire Interface Communication with

Host at 9.09kbps and 62.5kbps

● 3.3V ±10%, -40°C to +125°C Operating Range

● ±8kV HBM ESD protection of 1-Wire IO Pin

● 10-Pin TDFN Package

• 3mm x 4mm TDFN Package

• 3mm x 3mm, Side-Wettable TDFN Package

Applications

● Automotive Secure Authentication

● Identification and Calibration Automotive Parts/Tools/

Accessories

● AEC-Q100 Grade 1

● IoT Node Crypto-Protection

● Accessory and Peripheral Secure Authentication

● Secure Storage of Cryptographic Keys for a Host

Controller

● Secure Boot or Download of Firmware and/or System
