Physical resilience to insider attacks in IoT networks: Independent cryptographically secure sequences for DSSS anti-jamming

Wireless communication is a key technology for the Internet of Things (IoT). Due to its open nature, physical layer wireless systems high-priority target an adversary whose goal disrupt normal behavior system. In particular, jamming attacks are one most straightforward and effective types attacks: information flow system stopped or severely disturbed. this paper, we propose method improve resilience IoT based on Direct-Sequence Spread-Spectrum (DSSS) techniques. Our proposal inspired by Moving Target Defense (MTD) paradigm. MTD strategies randomize components system, increasing effort attacker needs compromise We use state-of-the-art Cryptographically Secure Pseudo-Random Number Generators outputs as spreading sequences DSSS. The proposed generated in ad-hoc, independent, distributed way. show probabilistically that have robust cross-correlation properties. define multi-user model evaluate Bit-Error-Rate our presence two jammers: classical band-limited Gaussian noise jammer, insider smart jammer with knowledge sequence used proactively mitigates attack. quantify implementing proposal, function length power.
