Signature.ALG_AES_MAC_128_NOPAD is NOT AES-CMAC. Signature.ALG_AES_MAC_128_NOPAD is available since JavaCard version 2.2.0. This can be glimpsed from the Oracle JavaCard PP documentation on page 146. What you are looking for is Signature. ALG_AES_CMAC_128 which is available since JavaCard version 3....

It depends on the GP toolkit you are going to use to manage the applets and cards. Each toolkit have their own approaches. You can use open source or freeware GP toolkits (i.e. GlobalPlatformPro, GPShell, pyAPDUToolkit) where you have to manually set the keys and decide how you want to derive them. ...

Where do you get the card from ?

What is the brand and model of the card ?

Also, can you post the GP commands you issued with GlobalPlatformPro ?

Can you issue

Code: Select all

java -jar gp.jar -i

to get a printout of the information from GlobalPlatformPro ?

I am aware this is an old thread and here is something interesting. KOMSCO Common Criteria ST document states that they are using Infineon with IC Fabricator marking of 0x8100 (Infineon). It is found in page 13, section 8, Evaluated Configuration. Here's a quotation from the ST document: The TOE is ...

Found the answer.

JavaCard does not support following syntax:

Code: Select all

byte[] SYMBOLS = { ... };
for (byte b : SYMBOLS) { // <--- Not supported

You will still have to use the for loop:

Code: Select all

 for(short i = 0; i < (short) SYMBOLS.length; i++) :

Hi Thumb, The smart card industry world moves on a very very slow pace. We only recently see the practical implementation of JC 3.0.4 on smart cards and most of the smart cards and SIM cards are still being equipped with just JC 2.2.2 or 3.0.1/2. It will take a very long time before the industry mov...

Firstly declare the array of short totalKeyObjects = (short) 24; AESKey[] keys = new AESKey[totalKeyObjects]; Then afterwards loop through as needed and use the KeyBuilder to build the keys when you need to use them otherwise the keys are not initialized properly and are useless until initialized an...

There is no known method of accessing the U2F capacitive touch button on the K9 because the access method to the touch button is proprietary to Feitian. You only have Java card smart card CCID access. Entire FIDO function is proprietary only to Feitian including the HID and touch button access which...

SM2_PUB_KEY = (SM2PublicKey)KeyBuilder.buildKey(SMConstant.KEY_TYPE_SM2_PUBLIC, (short)512, false); The length field for key builder for the SM2 Public Key is incorrect. The length should be: SMConstant.KEY_LENGTH_SM2 Correct code should be: SM2_PUB_KEY = (SM2PublicKey)KeyBuilder.buildKey(SMConstan...
