Huan Huang;Lipeng Dai;Hongliang Zhang;Zhongxing Tian;Yi Cai;Chongfu Zhang;A. Lee Swindlehurst;Zhu Han
Emerging intelligent reflecting surfaces (IRSs) significantly improve system performance, but also pose a huge risk for physical layer security. Existing works have illustrated that a disco IRS (DIRS), i.e., an illegitimate IRS with random time-varying reflection properties (like a “disco ball”), can be employed by an attacker to actively age the channels of legitimate users (LUs). Such active cha...Show More
Active RIS-Empowered Signal Cancellation Attacks
Lipeng Dai;Chongfu Zhang;Siyuan Wang;Shilong Jia;Huan Huang;Kun Qiu
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

Illegal Intelligent Reflecting Surface Based Active Channel Aging: When Jammer Can Attack Without Power and CSI
Illegal intelligent reflecting surfaces (I-IRSs), i.e., the illegal deployment and utilization of IRSs, impose serious harmful impacts on wireless networks. The existing I-IRS-based illegal jammer (IJ) requires channel state information (CSI) or extra power or both, and therefore, the I-IRS-based IJ seems to be difficult to implement in practical wireless networks. To raise concerns about signific...Show More

Difficulties in controlling IRSs to form the optimized passive beamforming have rarely been considered in intelligent reflecting surface (IRS)-aided systems, which are summarized as follows: 1) sending the optimized passive precoding vectors to the IRS controller incurs significant control overheads; 2) implementing the optimized passive precoding needs to set massive modes in the IRS control circ...Show More
Silent Flickering RIS Aided Covert Attacks via Intermittent Cooperative Jamming
Reconfigurable intelligent surface (RIS) aided continuous cooperative jamming (CCJ) attack could enable jamming sources to be exposed to systems of enemies. Thus, enemies can mitigate the jamming attack by employing anti-jamming techniques. For a CCJ attack to be effective, both jamming sources and jamming signals need to be hidden from enemies. Hence, we propose to jam a hostile receiver in an in...Show More
