When using AES CMAC for authentication of OTA messages, we must not pad the user data before calling the CMAC function. This is unlike the DES MAC, where padding to the DES block size is mandatory. This bug was discovered when trying to talk OTA with AES to a sysmoISIM-SJA5. This patch makes the OTA AES interoperate with the card. Also, with this patch the cryptographic results of pySim/ota.py are identical to those of the java code org.opentelecoms.gsm0348.impl.crypto.CipheringManager Change-Id: I4b40b5857f95ccb21c35795abe7a1995e368bac3
