"overcomes sacrificing transmission speed for security, by directly integrating encryption using end-to-end deep learning, dynamically optimizing geometric constellation shaping... maximizes mutual information for authorized users while reducing it for eavesdroppers to <0.2 bits/ symbol for illegal users, rendering intercepted data indistinguishable from noise... dynamic GCS: each transmitted symbol encrypted using unique key... scalable/ compatible with existing infrastructure... global data/ cloud centers, 6G networks"
