This family of contactless memories supports the different interface and memory size needs as well as various security requirements for variable applications. The product series functional architecture (e.g. memory organisation, authentication) is the same for both proximity (ISO/IEC 14443) and vicinity (ISO/IEC 15693). This eases the system design and allows simple adaptation of applications from my-d proximity to my-d vicinity or vice versa. Applications are supported very flexible by setting the appropriate mode for the my-d product, starting with plain mode with a page locking mechanism up to various settings in secure mode for multi user / multi application configurations with tearing protected counters. In secure mode a strong cryptographic algorithm with 64 bit key length is additionally available for security mechanisms like mutual authentication and message authentication codes. User Area 1 up to 15 Sectors Administration Area Control of Memory Access Configurable Sector Size Key Area up to 14 Key Pairs Service Area Unique Serial Number Legend Blocks marked by cross hatch - Defined by chip manufacturer Figure 4 Memory principle of my-d products These powerful features make the contactless security memory product series my-d ready to cope with even high-end requirements. Architectural compatibility of all my-d products allow an easy migration path from simple to powerful demanding applications. Short Product Information 6 / 10 2002-07-30 my-d vicinity SRF 55V02S 3 my-d vicinity products my-d vicinity focuses on flexible memory and sector configuration with higher read/write distances. This family of contactless memory chips supplies the user with different memory sizes and optionally offers the use of security features meeting the requirements of variable applications. As special feature the EAS (Electronic Article Surveillance) mode is built in to achieve higher and more robust performance in the demanding EAS application. my-d vicinity products are available in two memory sizes as well as in plain mode and in secure mode: * my-d vicinity plain mode with plain memory allowing unlimited access (SRF 55VxxP). Thus the memory is organised in one sector. * my-d vicinity secure mode allowing to configure counters and to secure memory access by authentication measures (SRF 55VxxS). Thus the memory may be organised in up to 16 sectors with at least one sector in plain mode. * 2,5 KBit memory sizes 32 pages with 10 Bytes (8 byte user data) * 10 KBit memory sizes 128 pages with 10 Bytes (8 byte user data) * In security mode advanced functions are available. Please refer to the relevant data book for details. All my-d vicinity products comply to the standard ISO/IEC 15693 for contactless vicinity smart cards. The power supply and data are transferred to my-d products via an antenna. my-d vicinity is designed to communicate up to a typical operating distance of 120 cm with a contactless reader in an appropriate gate configuration. Short Product Information 7 / 10 2002-07-30 my-d vicinity SRF 55V02S 3.1 Circuit Description my-d vicinity consists of a EEPROM memory unit, an analog interface for contactless energy and data transmission, a control and a crypto unit.

Authentication Unit (optional use) Generates random numbers, checks and calculates message authentication code (MAC). Memory Unit 320 bytes organised in 32 pages with 8 + 2 bytes each. Control Unit -- Decoding and execution of the commands -- Anticollision method complying to ISO/IEC 15693. It allows the recognition of several labels in the field which may be selected and operated in sequence. -- Access to key-protected sectors is only permitted after authentication with an appropriate key. Only one sector is opened within a session. One sector is optionally configurable without key protection and authentication. -- Memory access to the pages according to the individual access conditions programmed for every page and every key * * * * Short Product Information 8 / 10 2002-07-30 my-d vicinity SRF 55V02S 3.2 System Overview The system consists of a contactless label on one hand and a contactless reader together with an antenna on the other. Operations on protected areas of my-d vicinity in secure mode require a mutual authentication with the reader. To achieve a high system security a Security Access Module (SAM) holds the algorithm for performing the mutual authentication and integrity check of all data exchange. Host System C Analog Circuitry Data my-d vicinity Label VICC SAM Antenna Identification Terminal Energy Figure 6 Contactless System Example * * VICC - Vicinity Card according to ISO/IEC 15693 optional SAM - Security Access Module with contacts according to ISO/IEC 7816 Contactless Energy and Data Transfer The operating distance between label and reader antenna is typically up to 120 cm in an appropriate gate configuration. The label antenna consists of a simple coil with a few turns. Contactless labels are passive. The RF communication interface allows to exchange data with 26 kbit/s. This high data transmission rate permits short transaction times. An intelligent anticollision function allows to operate more than one label in the field simultaneously. The anticollision algorithm selects each label individually and ensures that the execution of a transaction with a selected label is performed correctly without data corruption resulting from other labels. Short Product Information 9 / 10 2002-07-30 my-d vicinity SRF 55V02S Multi-Application Functionality my-d vicinity provides the possibility to use one large sector or several smaller ones with different sizes. Optionally, one sector can be opened without authentication to read e.g. additional label and issuer information. Thus, my-d vicinity meets the need of low cost memory applications like public transport as well as the more extensive needs of payment systems, which is also supported by the counter function. Two different key sets for each memory sector support systems using key hierarchies. System Security In the system design, special emphasis has been placed on security against fraud. The serial number is unique for each label and can not be changed. Access to the protected memory of the label is only possible after a mutual authentication (challenge/response) which is a function of the unique serial number, random number and key to be used. Authentication is only possible with a security access module, SAM, that holds the algorithm. Therefore, for all operations on the protected memory, the SAM calculates and checks by a message authentication code (MAC) the integrity of the transferred data. Thus, operations on the protected memory are key protected, and restricted by page-configurable access conditions. Short Product Information 10 / 10 2002-07-30 |
