Secure ASSP

AT98SC is a complete turnkey cost-effective single chip solution to add security in embedded systems (Servers/Routers, Peripherals, Set Top Boxes, PDAs…). It has been designed to serve anti-cloning, access control and hardware protection applications.

The first two devices of this product family, the AT98SC008CT and AT98SC032CT-USB, provide an embedded « crypto » application allowing strong authentication with digital signature, encryption, message digest and secure storage of user data (keys, etc.). It 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 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.

AT98SC incorporates many advanced security features embedded in Smart Cards secure products dedicated for Banking, ID and Pay-TV. Such features includes power and frequency protection logic, logical scrambling on data and address, power analysis countermeasures and Eeprom access control.
