Abridged Data Sheet  
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.
