Abstract

Jamming-resistant broadcast communication is crucial for safety-critical applications such as emergency alert broadcasts or the dissemination of navigation signals in adversarial settings. These applications share the need for guaranteed authenticity and availability of messages which are broadcasted by base stations to a large and unknown number of (potentially untrusted) receivers. Common techniques to counter jamming attacks such as Direct-Sequence Spread Spectrum (DSSS) and Frequency Hopping are based on secrets that need to be shared between the sender and the receivers before the start of the communication. However, broadcast anti jamming communication that relies on Pollards Rho Method. In this work, we therefore propose a solution called P-Rho Method to enables spread-spectrum anti-jamming broadcast communication without the requirement of shared secrets. complete our work with an experimental evaluation on a prototype implementation.
