Query: 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 a one-way function. The proposed scheme 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 and pilot contamination attacks. In contrast to
conventional nonsquare differential MIMO schemes, which require space-time
projection matrices designed via highly complex, discrete, and combinatorial
optimization, the proposed scheme utilizes projection matrices constructed via
low-complexity continuous optimization designed to maximize the coding gain of
the system. Furthermore, using a secret key generated from the true randomness
nature of the wireless channel as an initial value, the proposed continuous
optimization-based projection matrix construction method becomes a one
way-function (in a cryptographic sense), making the proposed scheme a physical
layer secure differential MIMO system. An attack algorithm to challenge the
proposed scheme is also devised, which demonstrate that the security level
achieved improves as the number of transmit antennas increases, even in an
environment where the eavesdropper can perfectly estimate channel coefficients
and experiences asymptotically large signal-to-noise ratios.
