Abstract: The present teaching relates to a communication authentication device that includes a data storage system, a first communication interface, a display screen, and a processor. The processor is connected to the data storage system, first communication interface, and display screen. The processor may be configured to: acquire a first message in a binary format via the first communication interface; decode the first message in the binary format in accordance with a message formatting standard (e.g., the H standard, which requires particular sizes of messages), to obtain a first decoded message in a text format; and transmit the first decoded message in the text format to the display screen for comparison purposes.
