Description

Based on ATMEL Smart Card chip design expertise and leadership. The

AT98SC032CT-USB is a fully integrated secure solution (Hardware and

Firmware) designed for computer security applications (e.g. Web portal

This secure chip features

“crypto” application allowing strong

authentication, one-time password generation, digital signature, data

encryption, message digest, random number generation and public key

generation. The administration application allows the management of

contents and configuration of the chip.

Data is permanently stored in a 32 KByte file system which is fully

customizable according to customer application requirements. Folders can

be password protected,, and file access rights can be defined to protect

user sensitive data and restrict access to cryptographic features.

The AT98SC032CT-USB includes a hardware 3DES engine and a 32-bit

crypto accelerator for public-key operations (RSA and Elliptic Curves

algorithms). The chip also features a hardware Random Number Generator

used to generate on-chip public keys and challenges during authentication

process.

Communication with the chip occurs through a USB 2.0 interface running up

to 12 Mbps. Compliance to the USB-CCID ensures an easy interaction with

Linux and Windows applications (no specific driver is required).

State-of-the-art security features embedded in ATMEL Smart Cards

(dedicated to Banking, ID and Pay-TV) are also included in the

AT98SC032CT-USB: power and frequency protection logic, logical

scrambling on data and address, power analysis countermeasures and

EEPROM access control.
