In the encryption, the distribution of light carrier is designed and implemented by using tunable wavelength filter array triggered chaotic sequence. In addition, the arrayed waveguide grating (AWG) router is rewritten with maximal length code (M-sequence) to act as encoder. In the decryption, symmetric scheme and balanced photo-detector is presented and reconfigurable mechanism is followed the encryption synchronously either public or private channel. Hence, the multiple access interference (MAI) is cancelled completely while chaotic sequence is varied synchronously in transmitter and receiver. Compared to previous reconfigurable scheme by triggered register and switches after AWG router, the simulation results show that the secret key number of proposed cryptography is significantly increased to avoid eavesdropping attack in physical layer.</span></p>}, journal={Proceedings of Engineering and Technology Innovation}, author={Chang, Yao-Tang and Huang, Jen-Fa and Huang, Yen-Chung and Liou, Yan-Tai}, year={2016}, month={Aug.}, pages={4–6} }
