I am using the transient array to store data. After the signature is computed, the data is encrypted with the 3DES key. After that, the data is transfered into APDU buffer and sent to the terminal. I am using the 2KB keys, so the signature in returned in two APDU responses. How can I confirm the integrity of that transient array?

Calculate MAC or CRC and then verify on the terminal side.
