N2 - Potential application of terahertz wave in future wireless communications has been explored exponentially. Compared with present communication techniques, the large bandwidth and high directionality of terahertz wave could achieve high-speed, large-capacity, and safe data transmission. However, owing to the openness and broadcast characteristics of wireless channels, terahertz links still suffer serious security threats. It is necessary to explore eavesdropping risks faced by terahertz wireless links in different scenarios, which could be helpful for the terahertz application in the next generation of wireless network. In this paper, we demonstrate a method for signal eavesdropping from a terahertz link by employing a 3-D printed polystyrene (PS) waveguide. Experimental measurement is conducted by a terahertz link with a data rate of 5 Gbps using a 16-QAM modulation method. The results show that, an eavesdropper (Eve) can invalidate the spatial distance modulation encryption technology and intercept signals successfully at any unauthorized location or distance, while the sender (Alice) and authorized receiver (Bob) fail to monitor its existence.
