Full path integrity correction in a reconfigurable intelligent surface based on compromised path detection

Abstract

The technology described herein is directed towards monitoring and maintaining path integrity of a wireless communications path between authorized entities, in which a reconfigurable intelligent surface is part of the signal path between a base station and a user equipment. In one example, an eavesdropping entity intercepts signals to and/or from a base station and user equipment via a reconfigurable intelligent surface. The change in the path integrity from the redirected signals can be detected, e.g., via actual angle of arrival and/or signal strength data that does not match expected angle of arrival and/or expected signal strength; measured versus expected time-of-flight can be used to validate the path. The reconfigurable intelligent surface includes a reconfigurable delay detection network can change capacitance/phase to delay subsequently communicated signals and mitigate the attack. In one implementation, generative adversarial network models are used in the monitoring and correction of the signal path.
