Abstract	Jamming attacks are well-known threats to wireless communications, but on the other hand they provide insights for researchers to design novel approaches to protect wireless communications. In recent years, friendly jamming is used by a number of research works to achieve the wireless medium access control. However, in these works, the friendly jammer relies on bit-level information to distinguish the allies' wireless transmissions from the enemies', which requires the received signals to be processed through demodulation steps and thus introduces a non-trivial reaction time delay for the friendly jammer. This reaction delay is undesirable as the transmissions need to be jammed while they are still on the air. To address this problem, we propose fast friendly jamming, which eliminates the need for demodulation and enables the friendly jammer to verify the received signals directly on the physical layer. We have implemented a prototype of the proposed techniques based on GNURadio and USRP, and performed real-world experiments to validate the proposed techniques. The experiment results show that the proposed techniques reduce the normal reaction delay of the friendly jammer by 81.9%-85.7%, and achieve the accurate distinction between allies' and enemies' transmissions.
