1-Wire SHA-1 Authenticator

General Description

Features

S Dedicated Hardware-Accelerated SHA-1 Engine

The DS28E10 combines secure challenge-and-response

authentication functionality based on the FIPS 180-3

specified Secure Hash Algorithm (SHA-1) with 224 bits

of one-time programmable user EPROM in a single

chip. Once written, the memory is automatically write

protected. Additionally, each device has its own guaran-

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

that is factory programmed into the chip. Memory writes

are performed 4 bytes at a time. A secure and low-cost

factory programming service is available to preprogram

device data, including the SHA-1 security data compo-

nents. The device communicates over the single-contact

1-Wire® bus. The communication follows the standard

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

in the case of a multidevice 1-Wire network.
