Latest Patents

One of his latest patents is focused on physical layer key generation. This technique provides a privacy protection method suitable for devices with limited computational ability. The key generation algorithm is based on OFDM waveforms, which significantly improves the key generation rate (KGR) by exploiting holistic Channel State Information (CSI). Additionally, a cross-layer encryption protocol based on this key generation algorithm and AES enhances the secrecy of encryption compared to traditional schemes, even when some generated keys are compromised.

Another significant patent by Wenhan Dai involves base station ordering for localization. This approach localizes a mobile device by utilizing the order of neighboring base stations (BSs) based on the received power of pilot signals. The agent is located within the intersection of corresponding higher-order Voronoi cells, assuming BSs are deployed according to a Poisson point process (PPP) and that signals are subject to log-normal shadowing. The tradeoff between the Average Localization Rate (ALR) and localization error probability is characterized, demonstrating that increasing the number of reported BSs generally reduces ALR and improves localization accuracy, albeit at the cost of increased localization error.
