DS2460

SHA-1 Coprocessor with EEPROM

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

The DS2460 SHA-1 Coprocessor with EEPROM is a

hardware implementation of the ISO/IEC 10118-3

Secure Hash Algorithm (SHA-1), eliminating the need

to develop software to perform the complex SHA

computation required for authenticating SHA devices

and for performing the validation of digitally signed

service data. The DS2460 communicates with a

microcontroller through the popular I²C interface.

Applications include hosts of access control and

electronic payment systems for token authentication

and service data validation as well as generation of

one-time-use encryption keys for short message

encryption and decryption for messages not exceed-

ing the length of a SHA-1 result, which is 20 bytes.

Dedicated Hardware-Accelerated SHA Engine

for Generating SHA-1 MACs

112 Bytes User EEPROM for Storing End
