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.
