  1. Modeling Wi-Fi Protected Setup Brute-Force Mitigations Using Markov Chains Progress Summary Lloyd Jones

  2. Topic Background • Wi-Fi Protected Setup (WPS) – technology used for easy connection to wireless devices • Simpler than remembering long WEP/WPA passphrase • Push-button and PIN method • Known weaknesses in WPS, susceptible to brute-force attacks • Goal is to model how different wireless router mechanisms can mitigate these attacks

  3. Progress Made Since Proposal • Refined problem solving approach by defining variables and equation that will be used • Researched common consumer router WPS delays/lockouts • Defined states for Markov chains (Not associated, M5 ACK, M7 ACK)

  4. Next Steps • Model “ideal” scenario with Markov Chains and graph results • Start to model other likely scenarios for comparison • Elaborate on Problem Statement and Literature Survey • Possibly perform real world testing? 

  5. Questions?
