Abstract (in Japanese) (See Japanese page) 
(in English) We have shown by simulation that a spatial-temporal spreading key encryption with spatial digital key transformation(DKX) technique can be used to achieve the effect of encryption on QAM (Quadrature amplitude modulation) symbols without excessive digital signal processing. Moreover, simulation results show that the physical layer cryptosystem using the DKX technique can achieve high confidentiality.
