Secure dual interface and contact PKI smart card controller

1.4.3 AES coprocessor

SmartMX is the first smart card microcontroller platform to provide a dedicated high

performance 128-bit parallel processing coprocessor to support secure AES. The

implementation is based on FIPS197 as standardized by the National Institute for

Standards and Technology (NIST), and supports key lengths of 128-bit, 192-bit, and

256-bit with performance levels comparable to DES. AES is the next generation for

symmetric data encryption and recommended successor to DES providing significantly

improved security level. A secure crypto library element for AES is available.

1.5 SmartMX interfaces

1.5.1 SmartMX contact interface

Operating in accordance with ISO/IEC 7816, the SmartMX contact interface is supported

by a built-in Universal Asynchronous Receiver/Transmitter (UART), which enables data

rates of up to 1 Mbit/s allowing for the automatic generation of all typical baud rates and

supports transmission protocols T=0 and T=1. Up to two additional I/Os are available.

1.5.2 SmartMX contactless interface

The optional contactless interface is fully compatible with ISO/IEC 14443 A as well as

NXP Semiconductors’ field proven MIFARE technology. A dedicated Contactless Interface

Unit (CIU) manages and supports communication using data rates up to 848 kbit/s. A true

anti-collision method (in accordance with ISO/IEC 14443-3) enables multiple cards to be

handled simultaneously.

The optional MIFARE functionality provided in configurations B1 (MIFARE 1K

implementation), B4 (MIFARE 4K implementation), D1 (MIFARE 1K implementation with

MIFARE simultaneous operation enabled) and D4 (MIFARE 4K implementation with

MIFARE simultaneous operation enabled) safeguard the interface compatibility with any

installed MIFARE infrastructure. The ability to run the MIFARE protocol concurrently with

other contactless transmission protocols implemented by the customer code (T=CL or self

defined) enables the combination of new services and existing applications based on

MIFARE (e.g. ticketing) on a single dual interface controller based smart card.

The MIFARE implementation on the SmartMX makes use of the approved true random

number generator and thus is not susceptible to attacks based on the predictability of

random numbers. This emulation is separated from the rest of the SmartMX by a firewall

that is part of the Common Criteria evaluation.

A tutorial software library for ISO/IEC 14443-3 and ISO/IEC 14443-4 is available to

support NXP Semiconductors’ customers for easy integration of the contactless

technology into current system solutions.

The input capacitance can be factory configured for either standard loop antennas or for

smaller antennas (such as “ID1/2” antennas). This is accomplished by setting the device

input capacitance to either the standard value or to a higher value.

1.5.3 SmartMX S2C interface

The S2C interface is intended for use with NXP Semiconductors NFC circuits (e.g. PN544)

in order to configure secure NFC systems, for example in mobile hand sets.
