DeepCover Secure Authenticator

General Description

Beneﬁts and Features

● ECC-256 Compute Engine

The DS28E36 is a DeepCover secure authenticator

that provides a core set of cryptographic tools derived

from integrated asymmetric (ECC-P256) and symmetric

(SHA-256) security functions. In addition to the security

services provided by the hardware implemented crypto

engines, the device integrates a FIPS/NIST true random

number generator (RNG), 8Kb of secured EEPROM, a

decrement-only counter, two pins of configurable GPIO,

and a unique 64-bit ROM identification number (ROM

ID). This unique ROM ID is used as a fundamental input

parameter for cryptographic operations and also serves

as an electronic serial number within the application. The

• FIPS 186 ECDSA P256 Signature and Veriﬁcation

• ECDH Key Exchange with Authentication Prevents

Man-in-the-Middle Attacks

• ECDSA Authenticated R/W of Conﬁgurable

Memory

● SHA-256 Compute Engine

• FIPS 180 MAC for Secure Download/Boot

Operations

• FIPS 198 HMAC for Bidirectional Authentication

and Optional GPIO Control

● Two GPIO Pins with Optional Authentication Control

• Open-Drain, 4mA/0.4V

DS28E36 communicates over the single-contact 1-Wire

bus at overdrive speed. The communication follows the

1-Wire protocol with the ROM ID acting as node address

in the case of a multidevice 1-Wire network.

• Optional SHA-256 or ECDSA Authenticated On/Oﬀ

and State Read

• Optional Set On/Oﬀ after Multiblock Hash for

Secure Boot/Download

The ECC public/private key capabilities operate from

the NIST defined P-256 curve and include FIPS 186

compliant ECDSA signature generation and verification

to support a bidirectional asymmetric key authentication

model. The SHA-256 secret-key capabilities are compli-

ant with FIPS 180 and are flexibly used either in conjunc-

tion with ECDSA operations or independently for multiple

HMAC functions.

● RNG with NIST SP 800-90B Compliant Entropy

Source with Function to Read Out

● Optional Chip Generated Pr/Pu Key Pairs for ECC

Operations

● 17-Bit One-Time Settable, Nonvolatile Decrement-

Only Counter with Authenticated Read

Two GPIO pins can be independently operated under

command control and include configurability supporting

authenticated and nonauthenticated operation including

an ECDSA-based crypto-robust mode to support secure-

boot of a host processor.

● 8Kbits of EEPROM for User Data, Keys, and

Certificates

● Unique and Unalterable Factory Programmed 64-Bit

Identification Number (ROM ID)

• Optional Input Data Component to Crypto and Key

Operations

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, invasive and noninvasive

countermeasures are implemented including active die

shield, encrypted storage of keys, and algorithmic methods.

● Single-Contact 1-Wire Interface Communication with

Host at 11.7kbps and 62.5kbps

● Operating Range: 3.3V ±10%, -40°C to +85°C

● 6-Pin TDFN-EP Package (3mm x 3mm)

Applications

● IoT Node Crypto-Protection

Ordering Information and Typical Application Circuit appear

at end of data sheet.

● Accessory and Peripheral Secure Authentication

● Secure Storage of Cryptographic Keys for a Host

Controller

● Secure Boot or Download of Firmware and/or System
