A data communication method for transmitting a data packet from a transmitter to a receiver includes providing a key to the transmitter and the receiver where the key includes a K-bit data pattern sensitive to the location of each data bit in the data pattern; appending the key to the tail of the data packet; transmitting the data packet with the key; receiving data bits at the receiver to form a received data packet; retrieving K data bits from the tail of the received data packet; and determining if the K data bits match the key. If the K data bits match the key, a first output signal having a first state indicating that the data packet is acceptable is provided. If the K data bits do not match the key, the first output signal having a second state indicating that the data packet should be rejected is provided.
