Swift Jamming Attack on Frequency Offset Estimation: The Achilles’ Heel of OFDM Systems


Frequency offset (FO) refers to the distinction within the operating frequencies of two radio oscillators. Failure to compensate for the FO might result in decoding errors, notably in OFDM systems. To correct the FO, wireless standards append a publicly known preamble to every frame before transmission. In this paper, we demonstrate how an adversary can exploit the known preamble structure of OFDM-based mostly wireless systems, notably IEEE802.11a/g/n/ac, to launch a terribly stealth (low energy/duty cycle) reactive jamming attack against the FO estimation mechanism. In this attack, the adversary quickly detects a transmitted OFDM frame and subsequently jams a small part of the preamble that's used for FO estimation at the legitimate receiver. By optimizing the energy and structure of the jamming signal and accounting for frame detection timing errors and unknown channel parameters, we empirically show that the adversary can induce a touch error rate close to , making the transmission practically irrecoverable. Such vulnerability to FO jamming exists even when the frame is shielded by efficient channel coding. We evaluate the FO estimation attack through simulations and USRP experimentation. We have a tendency to also propose 3 approaches to mitigate such an attack.
