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.

Cyber Vision plays a vital role in promoting a collaborative workflow that enhances synergy between IT and OT, ensuring secure operational production. Partnering with Cisco (Thailand), this study aims to bolster cybersecurity measures in the oil and gas (O&G) industry to protect against external cyber threats. Researchers plan to use Cyber Vision for protocol analysis, intrusion detection, vulnerability assessment, and behavioral analysis, providing valuable insights into the industry's security stance. Adhering to IEC 62443 and NIST 800-82 standards, Cyber Vision ensures the continuous, resilient, and safe operation of industrial processes by maintaining constant visibility into Industrial Control Systems (ICS). It comes pre-integrated with top-tier security information and event management (SIEM) and security orchestration, automation, and response (SOAR) platforms.

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.

Optical asymmetric key cryptography in RoFSO for high security using ring resonator system

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.

This paper investigates the effect of rapid thermal annealing (RTA) between 850 and 900°C. Platinum (Pt) atom will drive-into silicon structure by using RTA process and the influence of temperature. Therefore, we study the effects of temperature in RTA process to I-V characteristics of device are 850 and 900°C at 15 mins. After annealing process, the built-in voltage (Vbi ) is around 0.3-0.4eV, which means that Pt does not affect the device junction. The I-V characteristics after annealing show that at 900°C there is the worst leakage of current with slightly better than the forward current. In case of leakage current, it may occur from the Pt atom damage creation or trapping center in silicon structure.

This paper is aimed at investigating the way to reduce the Pt-doped effect on silicon N-Type photodetector. The influencing of Pt-doped on silicon mechanism is an important problem because the performance of semiconductor device may decrease as a result from this process. In this paper, the obtained experimental result has shown that the Roentgen radiation can be used to reduce the influence from Pt-doped process, where C-V characteristics are the parameters to study in this experiment, from which the Roentgen radiation characteristics may change because the silicon bulk absorbs radiation of about 60%. The results have indicated that the C-V characteristics are not significantly changed. This way, radiation may induce and reduce some of the defects in silicon bulk but C-V is without change. Accordingly, parameters should be investigated to explain the defects to confirm the influence of Roentgen radiation by I-V characteristics and carrier concentration.

In this paper, we have derived and presented a new concept of multi orthogonal photon states generated by using dark-bright soliton collision within the modified add/drop filter, which it is known as PANDA ring resonator. By using the dark-bright soliton conversion control, the obtained outputs of the dynamic states can be used to randomly form the multi orthogonal photon pairs, which can be available for computer and communication security applications.

Such a system is known as the PANDA ring resonator structure. By controlling the suitable input parameters and the control optical signals, the optical pulses are employed to form the gradient potentials, finally, the optical vortices (gradient optical fields/wells) are generated, which can be deployed in various applications. © 2011 World Scientific Publishing Company.
