Abstract

Correlated jamming, introduced in the 1980's as the optimal interference signal in information theory, aims to cancel the target victim signal in contrast to the more traditional jamming approach of adding noise-like interference. The recent surge of antenna-cancellation based technology with benign intention (including full duplex radio technology and friendly jamming for confidentiality) has reignited interest in correlated jamming attack in wireless security. Randomization is an effective technique for availability against such attacks; for instance, spread spectrum technology randomizes the channel access to counter jamming. However, spread spectrum technology assumes dividing the medium into multiple orthogonal channels, only one of which is accessed per time, and thus has an inherent spreading cost. Redundancy Offset Narrow Spectrum (RONS) offers a narrow spectrum technology that bypasses the spreading cost and effectively counters correlated jamming and further helps ensuring confidentiality.
