need help hf 14a snoop data analysis
We snooped the process of writing data(maybe increment process) to the card.
However, there are two parts that differ from the existing results.
I thought it would be a change.
I do not know what the value is.
The hypothesis test is repeatedly performed.
encrypted value?
random value?
Time-related values?
increment process?
If you play a replay with this apdu command
0B 00 91 0F 67 6E error occurs in the last instruction.
In the last reader command, there is an unknown value of apdu command part, data part, 4byte. This part was brute force, but failed.
I need help so much.

Re: need help hf 14a snoop data analysis
Correct, should be in desfire.
Read the desfire datasheet and see which commands your trace contains. It will help you in the process of analysing reader/tag communication.

Re: need help hf 14a snoop data analysis
I originally wrote in the Desfire category, but I did not have an answer and was in a hurry. I'm sorry.
How can I get a Desfire Data Sheet if I sign a deal with NXP? Is there any other way?
