Need some input on ARQC generation

[Nagaraju C M]

Hi All,

 

I am referring EMV v4.2 Book 2 Security and Key Management CR05 document to generate ARQC.  And generated ARQC. But I am in confusion that, the generated one is valid or not. Because no where I am not getting any samples. Please if someone provide me some sample or algorithm steps to generate ARQC, it will help me to verify generated ARQC.

 

Thanks,

Nagaraju

In SMAdapter interface we have defined the following methods:
verifyARQC
generateARPC
verifyARQCGenerateARPC

Please look for javadoc and signatures

These are generic methods for service all EMV variations.

but JCESecurityModule.java don't implement them (but more advanced EMV methods do:).
I plan do it in some future (So far, no one but me asking for it.:)
Samples will be also avaliable in coresponding JCESecurityModuleTest.java

You could try them against a card which you know the keys for?

Why not share some data and perhaps someone can confirm if yours are
correct?

Input data (perhaps components), clear keys, chip version and your
results would suffice?

This Thales Sim has the command partially implemented

, the .net source code is available. Take a look and see if it helps.
