In contrast with the upper-layer security, the physical-layer security for wireless communications can repel physical layer attacks such as eavesdropping control signals. As conventional physical-layer security schemes for multi-input single-output (MISO) communications, artificial noise (AN) and artificial fast fading (AFF) need high transmit power, while random phase (RP) can reduce the power drastically. This is because RP sets phases of transmit signals randomly and estimates their amplitudes that can minimize the transmit power under the constraint of correct signal detection by the legitimate user. A major problem of these schemes is that the desired signal can be intercepted by eavesdroppers (Eves) having multiple receive antennas. Thus, this report proposes an enhanced version of RP that multiplies the desired complex symbols by random patterns so that Eve with multiple antennas cannot detect the desired symbols even by employing diversity combining with blind algorithms. The above multiplication changes the statistical property of the desired symbol, which can destroy the basis of the blind estimation of the diversity combining weights and thus can hinder the blind diversity combining. Computer simulations of MISO QPSK demonstrate that the proposed scheme can prohibit Eve performing the blind diversity combining from detecting the desired symbols much more strictly than the conventional RP, while maintaining good transmission performance of the legitimate receiver. |
