Hi Jonathan ,
Do you have tried the Encrypted write for NTAG413DNA?
As described in doc an410314, section 5.2.1 Table14, step11.
What is the last 24 bytes mean?
And where are they from?
From the step before. we just can get the Encrypted data and the 16 bytes New IV
So , I was wondering where are the last 24 bytes from ?
Dear yang youyong,
I am going to guide you here through the data sheet since this information is under NDA I cannot tell you the information but guide you, as you can see the cmd here is the cmd.WriteData this command, please chekc how this command is constructed, after the length you can see that there is the data, and the data is the information calculated in step 9, my apologies if I cannot be specific but this information cannot be shared through this communication channel.

Dear yang youyong,
I am going to answer this in the internal case you submitted,since most of this information is under NDA we can guide you through the DS and application notes that are secured so this procedure is clear.
