short product information 10 2008-05-13 my-d? proximity 2 sle 66rxxs system overview 3.3 system overview the system consists of a host system, one or more my-d? proximity 2 cards and an iso ? iec 14443-3 compatible cont actless reader with an antenna. operation on protected areas of a my-d? proximity 2 in secure mode require mutual authentic ation 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 for integration of the algorithm into the reader. optionally, a se curity access modules (sam) contains the algorithm for per forming the mutual authenti cation and data integrity check. to access plain pages on a sle 66rxxs, the algorithm is not required on the reader. figure 3-3 secure my-d? proximity 2 rfid system 3.4 product versions to identify the different types of my-d? proximity 2 contactle ss memories special chip type information is coded into the manufacturer page (page 02 h , byte 0). the table below briefly describes the values of this byte for the different chip versions. table 3-1 chip information fo r different pr oduct variants sales code chip information byte sle 66r04s 10xx_x010 b sle 66r16s 10xx_x100 b sle 66r32s 10xx_x101 b host system identification terminal (pcd) c analog circuitry antenna picc data energy clock sle 66rxxs my-d? proximity 2 algorithm algorithm or sw sam
short product information 11 2008-05-13 my-d? proximity 2 sle 66rxxs supported standards 3.5 supported standards iso ? iec 14443-3 type a (parts 1, 2 and 3) tested according to iso/iec 10373-6 (picc test & validation) 3.6 command set the my-d? proximity 2 chip is compliant to the iso ? iec 14443-3 standard. a set of standard iso commands is implement ed to operate the chip. ad ditional to the iso/iec 14443 commands, a my-d? specific command set is impl emented. this facilitates the access to the on-chip integrated memory. to execute commands on plain memory pag es, no authentication is required. 3.7 multi-application functionality the my-d? proximity 2 secure mode provides t he possibility to use one large sector or up to 15 smaller ones of flexible size. optionally, one sector can be addressed without authentication re ading e.g. additional label and user information. the my-d? proximity 2 closes the gap between the diverging requirements for low cost memory and secure, value token applications. it s unique value counter functionality eases the implementation of value blocks and limited use. the hierarchical approach of a ke y pair enables custom ized applications co mprising different memory access. 3.8 security features the serial number is unique fo r each label and ca nnot be changed. acce ss to the protected memory of the label is protect ed by using mutual authentication. for all operations to the protec ted memory the authentication unit calculates and validates the message authentication codes (mac ) to verify the data integrit y. additionally a key pair and individually configurable access conditions secure t he access to the protected memory.
