Stupify: A Hardware Countermeasure of KRACKs in WPA2 using Physically Unclonable Functions | Urbi

Abstract:
------------------
Security protocols, specifically in wireless network has undergone several rounds of modifications and upgrades in order to prevent supplicant or authenticators from attackers either sitting physically around the wireless coverage area or being hooked up to a wired network connected to wireless clients. The latest security protocol in the series is WPA2 which has been implemented in most of the Wi-Fi stations. Recently a severe replay attack named Key Reinstallation AttaCK (KRACK) has shown that the handshake in WPA2 protocol suite can be compromised and enforce the stations to reuse an old set of initialization vectors (IVs). In this talk, we will discuss how to use an unconventional hardware security primitive named Physically Unclonable Functions (PUFs) to nullify the impact of KRACK by ensuring a mutual authentication before establishing the communication. In the conclusion, we show a demonstration of i) how the hardware intrinsic properties of a device can be leveraged to embed a PUF instance in each device, ii) a working prototype of PUF based authentication protocol using Z-Turn board integrated with dual-core ARM Cortex-A9 processor and Artix-7 FPGA.
