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
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 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.
