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. W eb portal

login, PKCS#11 or MS-CAPI, Two-factor authentication, etc.).

This

secure

chip

features

a

“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 W indows applications (no specific driver is required).
