Get Data APDU command different tags and response format

问题

As you may know, Gloabal Platform Card Specification defines a command named Get Data to retrieve some information from the smart card.

GlobalPlatformPro is one of the popular tools for communication with smart cards. When I list the installed applets on the card using this tool, I have the following output:

D:\3-TestTools\SmartCard>GP -list -d -v -i

As you see above, the tool extracted Card Info, Card Data and Key Info from the card using following APDU commands:

• Card Info : 80 CA 9F 7F
• Card Data : 80 CA 00 66
• Key Info : 80 CA 00 E0

Questions:

1. Tags E0 and 66 are mentioned in Global Platform Card Specification, but the tag 9F 7F don't! Where is it specification?

2. As it is mentioned in the Global Platform Specification, the format of Card Data (Tag 66) is defined in ISO/IEC 7816 Part 6. But in this document there is only a table as below:

As you see above, the contents of this table is really different from the output that I can see in GPP tool output. How I can interpret the outputs (Get Data APDU command responses)?

回答1:

(In context of Global Platform 2.2.1 and ISO/IEC 7816-6:2004)

• Tag 'E0' (Key Information Template):

  • Defined in Global Platform (see section 11.3.3.1 and tables 11-27 and 11-28).

• Tag '66' (Card data):

  • Defined in ISO 7816-6 -- it may contain tag '73' called "Discretionary Data Objects" described as "Concatenation of data objects not defined in ISO/IEC 7816" (see Table 6).

  • Global Platform defines the contents of tag '73' within tag '66' (Card data) as "Card Recognition Data" (see section 7.4.1.3, appendix H.2 and Table H-1). This definition is in line with ISO 7816.

• Tag '9F7F' (CPLC / Card Production Life Cycle Data):

  • Defined in "Visa Integrated Circuit Card / Card Specification" which is not public (but might be found using google). The Open Platform 2.0.1 (predecessor of GP) defines that CPLC should be retrievable with the GET DATA command -- but it does not tell the particular tag.

Hope this makes some sense...good luck!
