When reconfigurable intelligent surface (RIS) is used to initiate attacks without actively generating sources of jamming signals, signal cancellation attacks (SCAs) are the main methods. However, a passive RIS (PRIS) requires a lot of reflecting elements in order to obtain considerable SCAs when attacked systems limit signal leakage to non-target receivers. This puts the PRIS at high risk of being...Show More
