1. Principle Create a byte array char[] byteArray = new byte[8]; //The longer of the array you set, the more secret you can pry in the future.

I think that you are sending an APDU command case 1 (P3=0), just like:

Code: Select all

CLA INS P1 P2 Le

If your applet invoke the method

Code: Select all

setIncomingAndReceive()

, it will expect data from the APDU buffer, and if you don't send data, this exception will be throwed by smartcardio API.

The problem may be caused by the following several lines of code. Donot use apduBuffer.length for the outgoing length. And If the card does not support extended APDUs, you can't return more than 256 bytes in the response. apduBuffer[0] = (byte)((RSAPublicKey)publicKey).getModulus(apduBuffer, (short)...

You just forgot to switch to outgoing mode before setting the outgoingLength.

Code: Select all

apdu.setOutgoing();
apdu.setOutgoingLength((byte) 0x10);

The following part is quoted from GlobalPlatform Card Specification Version 2.1.1 You may need to use SHA-1 algorithm. 6.7.6.1 Load File Data Block Hash The Load File Data Block Hash is a redundancy check across the whole Load File Data Block to be transferred to the card and is present as a field i...

I don't think here is the best place to find the script for changing card ATR. You should ask your card provider for help.

You can implement mutual authentication as GP defined.

Usually, the structure of 24 byte key is ABA, where
A: the first 8 bytes of 16 byte key;
B: the next 8 bytes of 16 byte key.
