Secure ASSP AT98SC008CT Summary

Description
Based on ATMEL Smar t Card chip design exper tise and leadership. The AT98SC008CT is a fully integrated secure solution (Hardware and Firmware) designed for embedded systems (Servers/Routers, Peripherals, Set Top Boxes, PDAs, etc.). This secure chip has been designed to serve anti-cloning, access control and hardware protection applications. It provides an embedded crypto application allowing a strong authentication, digital signature, encryption, message digest and secure storage of user data (keys, etc.). The AT98SC008CT includes a hardware Triple DES supporting symmetric-key operations and a 32-bit crypto accelerator for public-key operations (RSA and Elliptic Curves signature algorithms). The chip comprises also a hardware Random Number Generator used to generate on-chip public keys and challenges during authentication process. Communication with the chip occurs through a SPI interface running up to 2 Mbps (UART interface will be implemented in the future). In addition to the crypto application, the chip
provides a robust communication protocol, a persistent data storage with secure memory management (access control, anti-tearing), and an administration application to manage contents and configuration of the chip. State-of-the-art security features embedded in Smart Cards secure products dedicated for Banking, ID and Pay-TV are also included in the AT98SC008CT. Including power and frequency protection logic, logical scrambling on data and address, power analysis countermeasures and EEPROM access control.
