2 my-d® product family

The my-d® products are designed to meet increased demands for security and design flexibility.

The family of contactless memory my-d® supplies the user with different memory sizes and

incorporates security features to enable considerable flexibility in the application design.

The functional architecture, meaning the memory organisation and authentication of my-d®

products is the same for both, my-d® proximity (ISO/IEC 14443) and my-d® vicinity

(ISO/IEC 18000-3 mode 1 or ISO/IEC 15693). This eases the system design and allows simple

adaptation between applications.

All my-d® products are available in plain mode with open memory access and in secure mode with

memory access controlled by authentication procedures.

Flexible controls within the my-d ICs start with plain mode operation and individual page locking for

more complex applications various settings in secure mode can be set for multi user / multi

application configurations.

In secure mode a cryptographic algorithm based on 64-bit key is available. Mutual authentication,

message authentication codes (MAC) and customized access conditions protect the memory

against unauthorized access. Configurable value counters featuring anti-tearing functionality are

suitable for value token applications, such as limited use transportation tickets.

Architectural interoperability of all my-d® products enables an easy migration from simple to more

demanding applications.

In addition, the my-d® light (ISO/IEC 18000-3 mode 1 or ISO/IEC 15693) is part of the my-d®

family. Its optimized command set and memory expands the range of applications to cost sensitive

segments.

3 SRF 55V02S my-d® vicinity secure

my-d® vicinity secure focuses on flexible memory and sector configuration at longer read/write

distances.

All my-d® vicinity products comply with ISO/IEC 18000-3 mode 1 or ISO/IEC 15693 standards for

contactless vicinity smart cards. The power supply and data are transferred to the my-d® products

via an antenna. The my-d® vicinity is designed to communicate within the operating distance of up

to 1.5m depending on appropriate reader antenna configurations.

3.1 Circuit Description

The my-d® vicinity is made up of an EEPROM memory unit, an analog interface for contactless

energy and data transmission, a control unit and a crypto unit.

• Analog Contactless Interface:

The Analog Contactless Interface comprises the voltage rectifier, voltage regulator and system

clock to supply the IC with appropriate power. Additionally the data stream is modulated and

demodulated.

• Operational mode

The access to the memory depends on the actual mode of the my-d® vicinity. The memory is

accessed according to plain or secure mode after the VICC is selected.

• Authentication Unit (optional use)

The Authentication Unit generates random numbers, calculates and verifies the message

authentication codes (MAC).

• Memory Unit

The Memory Unit consists of 320 bytes organised in 32 pages each of 8 user and 2

administration bytes.

• Control Unit

The Control Unit decodes and executes all commands. Additionally the control unit is

responsible for the correct anticollision and authentication flow.

3.2 Memory Principle

The my-d® vicinity secure features secure memory access.

The User / Key Memory with its flexible organisation permits up to 14 independent secure sectors

of a variable size each protected with a 64 bit key pair. Only after a successful authentication a

single sector is accessible. In addition, one freely programmable plain sector is available for

general purpose use.

The service area contains the UID and manufacturer data. The service area cannot be changed.

The administration area comprises the access conditions and sector information.

3.3 System Overview

The system consists of a contactless label and a contactless reader together with an antenna.

Operations on protected areas of my-d® vicinity in secure mode require mutual authentication

between the label and the reader. To achieve high system security the my-d® security algorithm

has to be integrated into the reader. A license can be obtained from Infineon Technologies.

Optionally, a Security Access Modules (SAM) contains the algorithm for performing the mutual

authentication and data integrity check.

Contactless Energy and Data Transfer

The read / write distance is up to 1.5 m depending on an appropriate reader antenna configuration.

The label antenna consists of a simple coil with few turns. Contactless labels are passive. The RF

communication interface exchanges data with data rates of up to 26 kbit/s.

An intelligent anticollision function enables operation of more than one label in the field

simultaneously. The anticollision algorithm selects each label individually and ensures that the

my-d® vicinity secure

SRF 55V02S

Short Product Information 10 / 10 2007-07-02

execution of a transaction with a selected label is performed correctly without data corruption

resulting from other labels.

Multi-Application Functionality

The my-d® vicinity secure mode provides the possibility to use one large sector or up to 15 smaller

ones of flexible size.

Optionally, one sector can be addressed without authentication reading e.g. additional label and

user information.

The my-d® vicinity closes the gap between the diverging requirements for low cost memory and

secure, value token applications. Its unique value counter functionality eases the implementation of

value blocks and limited use.

The hierarchical approach of a key pair enables customized applications comprising different

memory access.

System Security

In the system design, substantial emphasis has been placed on security against fraud.

The serial number is unique for each label and cannot be changed. Access to the protected

memory of the label is only granted after a mutual authentication.

For all operations to the protected memory the authentication unit calculates and validates the

message authentication codes (MAC) to verify the data integrity. Additionally a key pair and

individually configurable access conditions secure the access to the protected memory
