Quantum Learning Based Nonrandom Superimposed Coding for Secure Wireless Access in 5G URLLC
Dongyang Xu, Pinyi Ren
Secure wireless access in ultra-reliable low-latency communications (URLLC), which is a critical aspect of 5G security, has become increasingly important due to its potential suppo…
Fundamental Tradeoffs in Uplink Grant-Free Multiple Access with Protected CSI
Dongyang Xu, Pinyi Ren, Yichen Wang +1
In the envisioned 5G, uplink grant-free multiple access will become the enabler of ultra-reliable low-latency communications (URLLC) services. By removing the forward scheduling re…
Rethinking Secure Precoding via Interference Exploitation: A Smart Eavesdropper Perspective
Qian Xu, Pinyi Ren, A. Lee Swindlehurst
Based on the concept of constructive interference (CI), multiuser interference (MUI) has recently been shown to be beneficial for communication secrecy. A few CI-based secure preco…
Independence-Checking Coding for OFDM Channel Training Authentication: Protocol Design, Security, Stability, and Tradeoff Analysis
Dongyang Xu, Pinyi Ren, James A. Ritcey
In wireless OFDM communications systems, pilot tones, due to their publicly known and deterministic characteristic, suffer significant jamming/nulling/spoofing risks. Thus, the con…
Hierarchical 2-D Feature Coding for Secure Pilot Authentication in Multi-User Multi-Antenna OFDM Systems: A Reliability Bound Contraction Perspective
Dongyang Xu, Pinyi Ren, James A. Ritcey
Due to the publicly known and deterministic characteristic of pilot tones, pilot authentication (PA) in multi-user multi-antenna orthogonal frequency-division multiplexing systems…
Optimal Grassmann Manifold Eavesdropping: A Huge Security Disaster for M-1-2 Wiretap Channels
Dongyang Xu, Pinyi Ren, James A. Ritcey
We in this paper introduce an advanced eavesdropper that aims to paralyze the artificial-noise-aided secure communications. We consider the M-1-2 Gaussian MISO wiretap channel, whi…
