Sažetak
Motivated by the ubiquity of wireless devices, we consider the following problem: how can two devices that do not share any secrets establish a shared secret key over a wireless radio channel in the presence of a communication jammer? An inherent challenge in solving this problem is that known anti-jamming techniques (e.g., frequency hopping or direct-sequence spread spectrum) which should support device communication during the key establishment require that the devices share a secret spreading key (or code) prior to the start of their communication. This requirement creates a circular dependency between anti-jamming spread-spectrum communication and key establishment. To the best of our knowledge, this dependency has so far not been addressed in this setting. In this work, we propose an Uncoordinated Frequency Hopping (UFH) scheme that breaks this circular dependency, and enables key establishment in the presence of a communication jammer ; the key resulting from the UFH key establishment can then be used to support later coordinated frequency hopping communication. We perform a detailed analysis of our UFH scheme and show its feasibility, both in terms of execution time and resource requirements. Our analysis shows that, although our UFH scheme has lower communication throughput and incurs higher storage and processing costs, it achieves the same level of anti-jamming protection as (coordinated) frequency hopping (which, however, unlike UFH, cannot be used in scenarios where devices do not share secret spreading keys).
