A quorum-based channel hopping scheme for jamming resilience

Jamming attacks have become wireless security threats disrupting reliable RF communication. Frequency Hopping Spread Spectrum (FHSS) is a widely used technique for anti-jamming wireless communications. However, FHSS relies on the pre-shared secret key between the communication pair. However, secure key exchange is challenging. Recently, Uncoordinated Frequency Hopping (UFH) schemes have been studied to achieve resilient key establishment in presence of a jammer. However, existing UFH schemes either suffer from unguaranteed rendezvous. In this paper, we introduce an Jamming-Resilient Asynchronous-Symmetric UFH scheme, AJCH, for guaranteeing rendezvous.
