The present invention develops a wireless communication transmitting scheme which allows a desired receiver to stably receive data so that data are not tapped by a third party when a transmitter transmits data to the receiver in a wireless scheme. In particular, the third party not a desired receiver taps, a bit error probability of received data is maintained to have about 50%, so that the third party cannot substantially obtain valid data. A suggested scheme of the present invention may transmit security data in a state that a transmitter and a receiver do not have a secret key unlike an existing cryptography.
