    A new method for highly secured wireless transmission was proposed as optical asymmetric key cryptography in RoFSO. The optical equipment used for handling high security communication was a PANDA ring resonator and an add/drop filter. A PANDA ring resonator used the dynamic behavior of bright-bright soliton collision. The outputs of the dynamic states were used to form key suppression and key generation as a communication security application. An add/drop filter was used to recover the optical key from suppression and generate an optical asymmetric key (key for sending and key for receiving). Simulation results showed that the proposed design achieved optical asymmetric key cryptography in RoFSO. The sender's data was not perceived by an interferer because the ciphertext data signal was covered by a noiselike signal in a frequency domain of tunnel's form like a noiselike signal.

    A new optical data transmission technique through a highly secure tunnel using a crypto carrier was investigated. High speed, high-security communication was achieved with an add/drop filter system and PANDA ring resonator optical equipment. The technique employed coding-decoding generated by public and private optical keys in frequency and time domains using a high-security tunnel. This novel technique provided high speed optical communication using light processing without electric control circuits. Restrictions on the operation of various equipment parameters affected the optical data communication signal intensity. The suitable signal ray data intensity was less than 200% of the signal ray intensity used for generating the optical public and private keys. This new technique ran and transmitted encrypted data efficiently to the receiver.
