#118627 - DS2460 I2C Coprocessor Responding to: ???'s previous message |
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 can compute SHA-1 Message Authentication Codes (MAC) for use with 1-Wire SHA devices, such as DS1963S, DS1961S, DS2432, DS28E01-100. Furthermore, the device can compare MACs. The EEPROM provides storage for secrets plus user 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.
