Implementation and Evaluation of Physical Layer Key Generation on SDR based LoRa Platform
Yingying Hu, Dongyang Xu, Tiantian Zhang
Physical layer key generation technology which leverages channel randomness to generate secret keys has attracted extensive attentions in long range (LoRa)-based networks recently.…
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…
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 Independence-Checking Coding For Secure Uplink Training in Large-Scale MISO-OFDM Systems
Dongyang Xu, Pinyi Ren, James A. Ritcey
Due to the publicly-known deterministic character- istic of pilot tones, pilot-aware attack, by jamming, nulling and spoofing pilot tones, can significantly paralyze the uplink cha…
