AT98SC032CTUSB Summary
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 authentication, one-time password generation, digital encryption, message digest, random number generation generation. The administration application allows the contents and configuration of the chip. allowing strong signature, data and public key management of
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). 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.
