The photon splitting of an UV into entangled pair of different wavelengths using non-linear crystals is a complicated procedure in the quantum authentication process (QAP) as presented in the six states deterministic protocol (6DP). A simplified process is proposed; the photon splitting process is replaced with basic polarization splitting of a single wavelength in the visible range. The quantum states are prepared, as usual, using retardation wave-plates. The transmitting station sends to the receiver a sequence of random polarized pulses via a quantum channel. The receiver blindly flips the quantum states using half wave-plate before sending back to the transmitter. The transmission of quantum states is made within a secret time interval which, based on preset path length and pulse travel time, triggers the detection device, and eventually achieves authentication after two more iterations.
