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…

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…

Code-Frequency Block Group Coding for Anti-Spoofing Pilot Authentication in Multi-Antenna OFDM Systems
Dongyang Xu, Pinyi Ren, James A. Ritcey +1
A pilot spoofer can paralyze the channel estimation in multi-user orthogonal frequency-division multiplexing (OFD- M) systems by using the same publicly-known pilot tones as legiti…
