It was recently proposed to use quantum secure direct communication (QSDC), a branch of quantum cryptography, to secure data transfers from sender to receiver without relying on computational complexity. Despite the benefits of multiphoton, sending secret messages between several parties in a quantum channel still presents a challenge because the current multiphoton only considers two parties. When more parties are included, the scalability problem becomes apparent. Therefore, the scalable multiphoton approach is needed to allow secure sharing between the legal parties. The manipulation of level encoding provides new opportunities for more efficient quantum information processing and message sharing. This research aims to propose a strategy that uses four-level encoding with the multiphoton approach to share secret messages between multi-party. From the analysis conducted, it has been shown that a high number of level encoding can shorten the time taken for photon transmission between parties and an attacker has a lower probability of chances to launch an attack, however, communication will be affected due to high sensitivity to noise.

“…Since the central architecture of Software Defined Networking (SDN) paradigm may be beneficial to increase the security level in a network, TSN and SDN technologies can be combined in order to enhance the security aspect of real-time communication [28]. Li et al [29] proposes a methodology, which relies on SDN/NFV (Network Functions Virtualization) combining network state and time synchronization information to detect and mitigate the attacks against Precision Time Protocol.…”

Dedicated computers control the operation of Cyber Physical Systems such as in-vehicle architectures with the help of sensors and actuators. Securing the real-time communication technologies for in-vehicle platforms attracts the attention of the research community. IEEE 802.1 Time Sensitive Networking (TSN) task group targets the standardization of Ethernet-based deterministic communication technologies due to its high bandwidth and low cost. IEEE P802.1DG working group specifies the profile for secure and real-time automotive embedded systems relying on TSN, which is envisioned to be widely used in future in-vehicle platforms. In this paper, we present an elaborate review of the research work on the security of in-vehicle communication networks with TSN support, and define various Denial of Service (DoS) attack scenarios targeting the real-time traffic in in-vehicle networks. We evaluate the impact of our attack scenarios on the performance of two different realistic in-vehicle communication networks with varying sizes. Experimental results show that DoS attacks can lead to severe consequences disrupting the healthy operation of safety-critical functions in a TSN-compliant in-vehicle network.

“…1) The longer communication distance requires robust delay compensation; 2) The air interface protocol stack reduces the delay compensation accuracy of technologies such as PTP; 3) The larger and complex topologies requires low hardware and bandwidth overhead of timing functions; 4) The high-precision absolute time delivery should basically be compatible with 3GPP standards. Therefore, achieving sub-microsecond timing accuracy in mobile network with large-scale equipments in diverse scenarios at low cost challenges all the traditional methods [23] [24]. Their inability to simultaneously meet the demands in terms of precision, flexibility and cost has greatly hindered the realization of the vertical applications mentioned above.…”

Absolute time synchronization (timing) is a constant demand in various fields. There are many timing techniques at present. They are mainly based on dedicated equipments such as GNSS or specific protocols such as NTP, PTP, SIB16, etc. Different timing methods are applied according to the scenario, cost and demands for timing accuracy. Recently, the timing demands for some wireless scenarios have become increasingly urgent, like power IoT and auto-driving. However, due to the instability and complexity of radio link, the current methods can hardly meet the demands of high-precision and low cost simultaneously in mobile network. Here we propose a timing method over air interface based on physical layer signals (TAP). Periodic physical layer signals in both downlink and uplink channel are considered to reduce the impact of radio link instability on timing. We implemented the proposed method on an open source LTE software defined radio platform named OpenAirInterface and conducted a series of tests. Our tests prove that TAP can provide microsecond-level timing over the air interface, and it is more stable and precise than PTP. Further simulation shows that using TAP in 5G NR can improve the timing accuracy. INDEX TERMS Air interface, high-precision timing, IoT, physical layer, time synchronization.
