Novel soliton cryptography using optical key generated by orthogonal dark-bright soliton pair

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.

Novel optical cryptography using LIP signals generated by a PANDA ring resonator

We propose a novel optical cryptography using the dark-bright soliton conversion control in a modified add/drop (AD) 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 which can be available for communication security application, where finally, the key recovery can be obtained by controlling the AD filter outputs. The optical cryptography part consists of an AD filter which is used to generate the encrypted and decryption keys from the optical keys (LIP signals), and a Mach–Zehnder interferometer is also used for multiplexing and de-multiplexing operations. The simulation results obtained have shown that the proposed system can be achieved, which can be used to form high security communication. © 2011 Wiley Periodicals, Inc.

Public key suppression and recovery using a PANDA ring resonator for high security communication

An interesting security technique that uses the dark-bright soliton conversion control within the microring resonator is proposed. The obtained outputs for a dark-bright soliton dynamic state can be controlled and used to form the public key suppression for communication security application. However, a good design should be possible to be fabricated; therefore, by using the parameters based on the practical device parameters, the simulation results obtained have shown that the proposed system can indeed be achieved. The public key suppression and public key recovery can be used in a highly secure communication system and has potential applications in optical cryptography.
