1. Lloyd, Jonathan C. Location Specific Entropy as a Metric for Unauthenticated Trustworthiness in Distributed and Crowd-Sourced Systems.

Degree: MS, Department of Electrical and Computer Engineering, 2019, California State Polytechnic University – Pomona

With the explosive growth in network connected computation devices, many new problems and opportunities arise. These computational devices may be operated by disparate, untrusting parties as they move about the real world. Crowdsourcing and distributed systems have developed to take advantage of these trends but participating in these solutions has its own challenges. For example, the Waze navigation service has been shown to be susceptible to false information from an attacker. This work proposes a potential method for establishing trust to the limited extent that other participants are geographically nearby via inspection of observational data. A simulation is developed to mimic localization by trilateration (GPS). The residuals of the localization are used to generate a location descriptive pseudo random entropy observation for each agent. These entropy observations are then featured and compared for defensibility against attacks. An acceptability criterion is proposed for conditional trust based upon statistical similarity of observation, and a trust graph is formed and analyzed. A distant simulated hostile observer is introduced and a statistically significant boundary between the observations of the distant hostile and the local network is identified. It is postulated that it is possible for a crowd sourced service provider to segment bad actors with simple cluster analysis algorithms, or for distributed agents to deny access to hostile agents with straightforward statistical metrics. Advisors/Committee Members: Nelson, Phyllis R. (advisor), El Naga, Halima (committee member).
