Abstract: It's illustrated a method to detect a message compatible with the OTA standard (Over The Air) and affected by a wrong ciphering. The method comprises the steps of receiving the ciphered OTA message; deciphering the OTA message; reading a counter field (PCNTR) of padding bytes in the deciphered OTA message and reading corresponding padding bytes in the OTA message deciphered; detecting at least one bit 1 in at least one of the padding bytes of the OTA message deciphered, said at least one bit 1 being indicative of the wrong ciphering.
