Cybertwin is a promising networking paradigm that supports complex wireless interconnectivity and enhances reliable communications by using edge capability in different applications. However, the computation-heavy phased-array weight vector generation is the significant barrier for the implementation of physical layer security (PLS) for millimeter-wave (MMWV) communications in cybertwin-driven scenarios, like vehicle-to-everything (V2X) applications. In this paper, we propose a low-complexity phased-array PLS scheme in MMWV wireless communications for cybertwin-driven V2X applications. The computational complexity is much reduced in a cost-effective way, where the transmitting phased-array weight vectors are updated at the symbol rate by randomly swapping the pre-calculated initial weight vector elements instead of directly calculating a new weight vector. Performance evaluation shows the proposed scheme possesses a lower computational complexity than the compared PLS schemes. The simulation demonstrates that the constellations are scrambled at undesired directions, while the constellation at target direction remains clear and constant. Thus, the communication secrecy is preserved for the receiver at the target direction in cybertwin-driven vehicular communications. Finally, we demonstrate that the proposed scheme achieves good security performances in terms of symbol error rate (SER) and secrecy outage probability. [ABSTRACT FROM AUTHOR] |
