Physical Layer Security of Generalised Pre-coded Spatial Modulation with Antenna Scrambling
We now advocate a novel physical layer security solution that is unique to
our previously proposed GPSM scheme with the aid of the proposed antenna
scrambling. The novelty and contribution of our paper lies in three aspects: 1/
principle: we introduce a `security key' generated at Alice that is unknown to
both Bob and Eve, where the design goal is that the publicly unknown security
key only imposes barrier for Eve. 2/ approach: we achieve it by conveying
useful information only through the activation of RA indices, which is in turn
concealed by the unknown security key in terms of the randomly scrambled
symbols used in place of the conventional modulated symbols in GPSM scheme. 3/
design: we consider both Circular Antenna Scrambling (CAS) and Gaussian Antenna
Scrambling (GAS) in detail and the resultant security capacity of both designs
are quantified and compared
