New chip hides wireless messages in plain sight

Researchers at Princeton University have developed a new millimeter-wave wireless microchip that secures wireless transmissions on 5G networks without curtailing their speed or efficiency. Rather than rely on encryption, the device disrupts the path of a transmission, making it look like noise to potential eavesdroppers and confounding attempts to reconstruct the data. The technology can be incorporated into a standard silicon chip and work in conjunction with traditional encryption techniques.
