I have read the EMV spec.
And I have finished some simple steps. Now I need to validate the card. How can I validate the card with "internal authenticate" ? Can I use some public key and signature method ?
JavacardOS will not accept order any more, please contact our partner Feitian online Store:

And I donot want to run any applet with it - I just want to read the unique ID of the card to validate that the card is not created manually and validate that t...

Re: secure channel initiation mode implicit
The steps are much the same as the explicit, except there is not INIT-UPDATE/EXT-AUTH commands to deal with. When the first secured APDU is received (CLA = 0x84), you follow the process to generate session keys and verify the MAC. The card spec outlines how to generate a MAC with the session keys. ...

secure channel initiation mode implicit
Hello, it's me again.
Can somebody here explain the mechanism of secure channel initiation on mode implicit? I already have a look at the specification, the introduction about GlobalPlatform initiation mode implicit is very simple.
So hope expert guide me how to do it.
Any help is appreciated.

Re: ECDSA signature

Is there anyway to use the same random number so that I can get the same ECDSA signature?

ECDSA signature
I have created an EC key pair and I tried to use the same data and EC private key to generate ECDSA signature. But I found that each signature is different from the previous one. Why the value is different? What can I do to make the signature same? Signature sig1 = Signature.getInstance(Signature.AL...

derived keys
My card needs to implement the mutual authentication. For that purpose the outside card application and the card must share the set of secret keys. The first key is relevant for encryption and the other for the MAC calculation. At this point I am putting these keys on the card during the personaliza...

Re: Difference between contact and contactless card
In fact, there is no difference between the contact and contactless card in APDU field. However,in the case of contact interface, for APDU command between T=0 and T=1 there is a little difference. T=0 protocol cannot distinguish between the Lc and Le bytes. So it uses specific status words, such as ...

Leak of memory on java card
I have installed an applet on a java card. And the applet runs for 3 times without deselecting the applet.Then it returns "6F 00". Is that due to javacard leak of memory?
