DS28E15

1-Wire SHA-256 Secure Authenticator

with 512-Bit User EEPROM

General Description

Features

The DS28E15 combines crypto-strong bidirectional

secure challenge-and-response authentication func-

tionality with an implementation based on the FIPS

180-3-specified Secure Hash Algorithm (SHA-256). A

512-bit user-programmable EEPROM array provides

nonvolatile storage of application data. Additional pro-

tected memory holds a read-protected secret for SHA-

256 operations and settings for memory protection

control. Each device has its own guaranteed unique

64-bit ROM identification number (ROM ID) that is fac-

tory programmed into the chip. This unique ROM ID is

used as a fundamental input parameter for cryptographic

operations and also serves as an electronic serial num-

ber within the application. A bidirectional security model

enables two-way authentication between a host system

and slave-embedded DS28E15. Slave-to-host authenti-

cation is used by a host system to securely validate that

an attached or embedded DS28E15 is authentic. Host-

to-slave authentication is used to protect DS28E15 user

memory from being modified by a nonauthentic host. The

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.
