Abstract
A communication system capable of avoiding crosstalk with a simple structure. By assigning the same identification-number data to a transmitter and a receiver, performing the logical operation for the identification-number data with the logical operation circuit of the transmitter and the receiver, and detecting errors in the operation results by using error detection circuit, it is possible to perform enciphering and certifying without increasing communications traffic and thus avoid crosstalk with a simple structure because it is unnecessary to add and transmit the identification-number data.
