Analysis of the resilience of distributed ledger–based Smart Dust sensor networks to attacks and interference

Abstract

A mathematical approach is proposed for evaluating the resilience of a distributed ledger of SmartDust-class sensor microsystems under conditions of cyber-physical attacks and industrial interference. A stochastic model of the trusted sensor network is developed, incorporating the probabilities of node compromise, telemetry packet loss, and data verification errors. Analytical expressions are derived for the indicators of data trustworthiness, latency, and energy reliability of the system. The simulation results demonstrate the influence of network topology parameters and attack intensity on the integral resilience index of the sensor infrastructure.
