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.

We propose a novel method of an optical cryptography using the dark-bright soliton conversion control in a modified add/drop optical filter. By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression for communication security application, in which the key recovery can be obtained by controlling the add/drop filter outputs. The optical cryptography consists of an add/drop filter which is used to generate the encryption and decryption keys from the optical keys (LIP signals). A Mach-Zehnder interferometer is used for multiplexing and de-multiplexing operations. Simulation results obtained shows, that the proposed system can be used to form a high security communication system.
A new method of optical cryptography using dark-bright soliton conversion control within a modified add/drop optical filter is proposed. A pair of optical keys is randomly generated and transmitted into the transmission line, where finally the corrected keys between Alice (sender) and Bob (receiver) can be retrieved. In principle, the coincidence (orthogonal) dark-bright soliton pair has shown promising behaviors, especially when they propagate into the π/2 phase shifter, i.e. beamsplitter, the shift in phase of π/2 between dark and bright solitons is occurred and separated. Such behaviors can be used to form the orthogonal light modes (solitons), which are useful for cryptographic application, where in this case the long-distance cryptography can be easily managed. We have derived and presented a new concept of multi-orthogonal solitons generated by using dark-bright soliton pulses within the modified add/drop optical filter, which is known as a PANDA ring resonator. By using the dark-bright soliton conversion control, the obtained output of the dynamic states can be used to randomly form the multi-orthogonal soliton pairs, which can be available for computer and communication security applications, especially for long-distance link.
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.

By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression which can be available for communication security application, where finally, the key recovery can be obtained by controlling the add/drop filter outputs. The optical private tunnel system consists of data sending section, key learning section and peering section that use an add/drop filter which is used to generate the shape of tunnel from the optical keys, and a Mach-Zehnder interferometer is also used for multiplexing and de-multiplexing operations.
