Noncoherent Massive MIMO With Embedded One-Way Function Physical Layer Security

We propose a novel physical layer security scheme that exploits an optimization method as one-way function. The proposed builds on nonsquare differential multiple-input multiple-output (MIMO), which is capable of noncoherent detection even in massive MIMO scenarios and thus resilient against risky pilot insertion contamination attacks. In contrast to conventional schemes, require space-time projection matrices designed via highly complex, discrete, combinatorial optimization, the utilizes constructed low-complexity continuous maximize coding gain system. Furthermore, using secret key generated from true randomness nature wireless channel initial value, optimization-based matrix construction becomes function, making secure An attack algorithm challenge also devised, demonstrates level achieved improves number transmit antennas increases, environment where eavesdropper can perfectly estimate coefficients experience asymptotically large signal-to-noise ratios.
