The chip includes also a MAP which is based on a 1088 bits processor architecture. It processes modular multiplication, squaring and additional calculations up to 2176 bit operands. Internal Modular Arithmetic Processor (MAP) and DES accelerator are designed to speed up cryptographic calculations using Public Key Algorithms and Secret Key Algorithms. This product is based on a STMicrolectronics 8 bit CPU and includes on chip memories: User ROM, User RAM and User EEPROM with state of the art security features. ROM, RAM and EEPROM memories can be configured into partitions with customized access rules. Figure 2. Block Diagram Access from any memory area to another are protected by hardware FIREWALLS. Access rules are User defined and can be selected by mask options or during the life of the product. The chip includes a DES accelerator which is accessible via cryptographic system ROM software library. As with all the other ST19X products, serial interfaces fully compatible with the ISO7816 standard for Smartcard applications are available. In addition, the chip includes an 2.0 standard USB serial interface and 2 serial access ISO7816-3 I/Os. A CRC calculation block is also available and is directly accessible by the User. This product is manufactured using an advanced highly reliable ST CMOS EEPROM technology.

CRYPTOGRAPHIC LIBRARIES For an easy and sufficient use of the Modular Arithmetic Processor (MAP), ST proposes a complete set of firmware subroutines. This library is located in a specific ROM area. This library saves the operating system designer from coding first layer functions and allows the designer to concentrate on algorithms, Public Key Cryptography and Secret Key Cryptography protocols implementation. This library contains firmware functions for: ASYMMETRICAL ALGORITHMS - loading and unloading parameters and results to or from the MAP - calculating Montgomery constants - basic mathematics including modular squaring and multiplication for various lengths - modular exponentiation using or not the Chinese Remainder Theorem (CRT) - more elaborate functions such as RSA signatures and verifications for modulo length up to 2176 bits long, DSA signature and authentication. - full internal key generation for signatures/ verifications. This guarantees that the secret key will never be known outside the chip and contributes to overall system security. - long random number generation - RSA up to 2176 bits - DSA up to 1088 bits - SHA-1 - RSA key generation SYMMETRICAL ALGORITHMS - DES, triple DES, DESX computations - CBC chaining mode - Loading/Unloadings from/to registers are secured against SPA Information furnished is believed to be accurate and reliable.
