Item type:Item, Enhancing QKD via Multi-Photon-Lane Systems With a Card-Shuffling-Based Approach(2025-01-01) ;Chaiyasoonthorn, Sawatsakorn ;Youplao, Pirada ;Youplao, Phichai ;Sarapat, NapatsakonMitatha, SomsakThis paper introduces a modified quantum key distribution (QKD) protocol based on card-shuffling, designed to enhance security against eavesdropper photon number splitting (PNS) strategies. The proposed technique accommodates light pulses with few photons, substantially augmenting the effectiveness and reliability of QKD. It can be implemented as multi-photon-lane systems, enabling concurrent key distribution to multiple users or amalgamation of key data to amplify individual use r key rates. The study assesses the proposed technique utilizing three well-established polarization-encrypted QKD protocols, BB84, B92, and SSP99, and simulations utilizing 4-photon lane systems with wavelengths of 800 nm, 1300 nm, and 1550 nm. The findings, encompassing correlations such as useful key rate, maximum key distribution distance, quantum bit error rate, and photon number probability, are analyzed and compared under different conditions. The outcomes reveal that combining the technique with BB84-based systems employing 1300 nm light pulses and a photon number probability of 1.0 attains a maximum QKD effectiveness of 12.34 Gbit-km/s. Moreover, the effectiveness can be increased to 49.36 Gbit-km/s by implementing the proposed 4-photon-lane system as the serial key-combining scheme. The potential of using multi-photon-lane implementations alongside the proposed technique to enhance the effectiveness and reliability of QKD is theoretically investigated and discussed. - Some of the metrics are blocked by yourconsent settings
Item type:Item, High frequency generation based-on nonlinear micro ring resonator for frequency band enhancement(2014-01-01) ;Udomariyasap, P. ;Noppanakeepong, S.Pornsuwancharoen, N.Propose the simulation of THz carrier frequencies using the small device and a Gaussian beam propagating within the device system. We found that the generated output power with the high frequency can be achieved. This consisted of a serial nonlinear micro ring resonator system for generating pulse and signal filter by Add/Drop filter, a technology optical communication by the micro ring resonator which generates the THz frequency multiple, whereas channel capacity in term of multi frequency bands can be provided by optical Add/Drop multiplexing. The increase in the number of channel capacity can be obtained by the increase in frequency density, while the security was introduced by the specific frequency filter, which was operated by the central operator. The optical micro ring resonators for THz frequency generation and enhancement are reviewed. The advantage of proposed system can be implemented by using the simultaneous optical communication system. © (2014) Trans Tech Publications, Switzerland. - Some of the metrics are blocked by yourconsent settings
Item type:Item, Highly secured optical communication by optical key and identification address(2013-05-01) ;Juleang, P. ;Putthacharoen, R. ;Mitatha, S.Yupapin, P. P.We propose a novel design of optical network system that can be used for optical communication security and receiver identification. The data signal is secured by using both the optical encryption key and optical address of the receiver before transmission, where finally the receiver who has the valid optical decryption key and optical address can decrypt the Ciphertext. In this paper, a PANDA ring resonator, optical add/drop filter and Mach-Zehnder Interferometer are used for the encryption, decryption and identification processes without any electronic control circuit. The encryption and decryption keys are formed by dark-bright soliton propagation within the PANDA ring resonator. Simulation results obtained have shown that the secured optical network can be achieved optically and realized. - Some of the metrics are blocked by yourconsent settings
Item type:Item, Fast light generation using GaAlAs/GaAs waveguide(2012-12-01) ;Afroozeh, A. ;Bahadoran, M. ;Amiri, I. S. ;Samavati, A. R.Ali, J.Generation of fast light pulses through a nonlinear microring system is an attractive research challenge for high speed optical and quantum computer, optical communication networks and secured communication. In this paper generation of fast light through GaAlAs/GaAs waveguides with fabricated Micro Ring Resonator is reported. Using multistage system, the attosecond pulse can be generated. Simulation results obtained have shown that the generation of a very narrow full-width at half maximum (FWHM) line width and sharp tip is achieved. We propose a new system of multistage micro ring resonators consist of four rings for optical communication system. Here, pulse width of 15 attosecond can be obtained, using proper parameters of the proposed system. © Penerbit UTM Press, Universiti Teknologi Malaysia. - Some of the metrics are blocked by yourconsent settings
Item type:Item, Data security transmission via a noisy channel(2011-05-02) ;Mitsophonsiri, K. ;Punthawanunt, S. ;Mitatha, S.Yupapin, P. P.We propose a novel method that can be used to perform the data verification and encryption by using the microring resonators incorporating an add/drop filter, where the confidentiality and integrity of information in optical communication can be formed. In this paper, the encryption is formed by the chaotic noise sophisticates irreversible and unpredictable in the nonlinear microring resonator. The proposed system is used to generate the message authentication code for maintaining data integrity, where the noisy signals are created by the microring resonator and combined with the encoded information to protect the man-in-the-middle attacks (decipher). By using the extremely small processing device, the proposed design can be easily applied to secure any form of communication in wireless network, mobile communication network and military applications with low power consumption and very high-speed procedures. - Some of the metrics are blocked by yourconsent settings
Item type:Item, A novel temporal dark-bright solitons conversion system via an add/drop filter for signal security use(2010-11-01) ;Siririth, W. ;Mitatha, S. ;Pingern, O.Yupapin, P. P.We propose a new design of a security scheme by using the nonlinear behaviors of temporal dark and bright solitons within a micro-ring resonator system for signal security application. When a dark soliton pulse is input into the proposed system, the chaotic signal is generated, where the required bright soliton pulse can be retrieved and detected by the add/drop filtering device. The chaotic wave form can be cancelled by using an add/drop device, which can be connected and used in the communication link. By using the appropriate ring parameters, simulation results obtained have shown that the soliton conversion can be performed. The ring radii used are within the ranges from 5 to 10 μms and A<inf>eff</inf>=0.100.50 μm<sup>2</sup>. In application, the chaotic signal is generated and formed by the dark soliton within a nonlinear micro-ring device. This can be seen by using the add/drop device, where the bright soliton is formed and detected, which is available to use in communication link. The different temporal soliton response time is seen, the response times of 169 and 84 ns are noted for temporal dark and bright solitons, respectively, which can also be used to form the security key. © 2009 Elsevier GmbH.

Item type:Item, Fast and slow light generation using chaotic signals in nonlinear microring resonators for communication security(2009-01-29) ;Pornsuwancharoen, Nithiroth ;Chalyasoonthorn, SawatsakornYupapin, Preecha P.We propose a new system of signal security using nonlinear micro ring resonators for optical communication system. When a soliton pulse Is input into the system, the chaotic signal Is generated and multiplexed into the optical link. The chaotic waveform can be canceled using an add/drop device connected into the transmission link. Using the appropriate ring parameters, the original signal can be retrieved. An other application results from the fact that the fast and slow light behaviors can be presented, and can be seen using the add/drop multiplexers. In some cases, we can generate signal to obtain the two identical "signal" and "ghost" signals, which are observed in a different time frame. In this application, communication security can be performed when the required information is multiplexed and performs the link using the chaotic signal, fast and slow light, and signal and ghost signals, where the original signal can be retrieved by the known clients. © 2009 Society of Photo-Optical Instrumentation Engineers.
