This 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.

This research presents a newly proposed design for a reliable protocol for wireless sensor networks, supporting large-scale smart farms. The protocol was tested and compared with previous methods. The results demonstrated a significantly higher data transmission success rate and a transmission speed approximately three times faster. Additionally, when the proposed reliable protocol was implemented in ten smart farms in Sukhothai province, it achieved a data transmission success rate of 99.07% and an average transmission time of 16.64 seconds, approximately three times faster than the previous method. These experimental outcomes confirm that the proposed reliable protocol meets the communication objectives outlined in its design, ensuring reliable, consistent, and timely data transmission.

A new automatic cultivation system was proposed using a forecasting algorithm for environmental control. Information used for the forecast was taken from real time data obtained by a wireless sensor system. The objective was the automation of suitable environmental cultivation methods. The proposed forecasting algorithm used historical data to predict future environmental control according to its goals. A real system was implemented and constructed to test the hypothesis. Results showed that the system had the required features. Environmental controls of the original system were compared with the proposed algorithm according to the created thresholds. The proposed forecasting algorithm controlled humidity in the soil at 98.26%, while the original system recorded do 69.33%, with humidity in the air controlled at 93.87% compared to the original system at 48.96%. This algorithm will be very useful to promote sustainable agriculture.

Optical Hash Function for High Speed and High Security Algorithm using Ring Resonator System
(2021-04-01)
Juleang, Pakom

Mitatha, Somsak
This work presents a novel security technique using the optical hash function to create a message digest algorithm in the wavelength domain. The optical devices used for high speed and high security algorithm handling comprised a PANDA ring resonator connected with an add/drop filter system. The PANDA ring resonator was introduced to access the dynamic behavior of bright-bright soliton collision within the modified add/drop filter. Outputs of the dynamic states formed key suppression as a high security application for optical cryptography. The add/drop filter was an essential device in the proposed design for optical hash function processing. Simulation outputs proved that the proposed technique obtained optical hash function in the wavelength domain for real time message digest creation. The wavelength of the data must be within 40% of the center wavelength of the system input signal. The integrity of the data was maintained by this highly secure process.

A novel optical checksum high speed approach for error detection is proposed for use in a multi tunnel wavelength domain. By using this technique, all processes were performed by passing light through optical hardware (PANDA ring resonator together with add/drop filter). Outputs achieved from dynamic states utilizing the bright-dark soliton conversion control was utilized to secure the optical checksum creation process. The add/drop filter was utilized as an essential device in the proposed system. The results proved that the proposed design could achieve optical checksum in wavelength domain for real time error detection. This method could also quickly create and check the accuracy of information using optical processes. The wavelength of the multi tunnels must be within 50% of the center wavelength of the input signal system to maintain data integrity for optical communication.

This work presents and discusses a method for evaluating a dynamic eddy-current damping (ECD) force that is automatically generated in response to eddy currents induced within a conductive plate while moving across a magnetic field in relative motion to a nearby stationary magnet. In the experiment, a Doppler shift frequency signal between the optical interference fringe frequencies was used to calculate the velocity of the moving conductive plate. The other relevant mechanical quantities acting on the plate, such as the displacement, acceleration, and resultant force, were then evaluated by performing numerical calculations of the velocity. Finally, the evaluation of the ECD force could be achieved by performing a calculation to remove the frictional force component from the resultant force. Furthermore, an approximation analysis used to calculate the value of the ECD force was proposed and compared with the measured value as well. From the experimental results, the combined standard uncertainty for evaluating the ECD force was approximately 3.57 mN, corresponding to 3.13% of the maximum eddy-current force of approximately 114.0 mN.

The multi-wavelength selection and switching system using the hybrid plasmonic add-drop ring resonator (HPARR) for optical communication is proposed for multi-carrier super-channel-based designed. The plasmonic polariton technique applied in the ring resonator mode to the alternate waveguide interferometer switches the multi-wavelength laser emission in the various ranges. The combination of curvature-coupled plasmon ring and substances with different refractive index allows switching the multi-wavelength emission to shorter the free spectrum range (FSR) and specific wavelengths, without an applied pump signal or adjusted the ring size. It is suitable for the super-channel of wavelength division multiplex (WDM) in the future optical network.
