TY - JOUR AU - Morrison, James AU - Rogers, Neil AU - Bahn, William PY - 2022/09/29 TI - Novel Implementation of a Keyless Concurrent Codes Spread-Spectrum (CCSS) Jam-Resistant Method in GNU Radio JF - Proceedings of the GNU Radio Conference; Vol 7 No 1 (2022): Proceedings of the 12th GNU Radio Conference KW - N2 - Current omnidirectional jam-resistant technology relies on shared secrets. This forces private networks to exchange keys before jamming is present and leaves public networks (like GPS or ADSB/Mode-S) unprotected. Given the proliferation of inexpensive Software Defined Radios (SDRs), robust jam-resistant options are more important than ever. This project implements the “BBC” codec–a keyless, concurrent codes spread-spectrum (CCSS) strategy–in GNU Radio. Initial testing of the BBC codec confirms theoretical performance estimates and suggests that BBC is a viable option to preserve information availability. Development is underway to provide an out-oftree (OOT) module for broader use within the GNU Radio community. UR - https://pubs.gnuradio.org/index.php/grcon/article/view/127
