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,
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.
