Hands-on Lab Activities

Computer lab setup

Lab 1 - Introduction to V2V (PDF)
How to set up an experimental environment for studying V2V security using our open-source software-defined radio testbed, V2Verifier. Configure and install V2Verifier, and run simple experiments. Estimated completion time: 60-75 minutes. 

Lab 2 - BSM Spoofing Attack (PDF)
Learn about BSM spoofing, a straightforward but dangerous attack against V2V communications. Configure and execute a BSM spoofing attack using V2Verifier, then enable IEEE 1609.2 security to observe the importance of security mechanisms like digital message signing and verification for V2V. Estimated completion time: 45-60 minutes. 

Lab 3 - BSM Replay Attack (PDF)
Investigate another serious type of attack against V2V communications, the BSM replay attack. Use the testbed to experiment with executing a BSM replay attack, then enable IEEE 1609.2 security and learn how that standard's mitigation mechanisms are designed to prevent this type of attack from being effective. Estimated completion time: 45-60 minutes. 

Lab 4 - Cellular Vehicle-to-Everything (C-V2X) (PDF)
Dig into the details of C-V2X, an expanding V2V technology based on cellular LTE and 5G technologies. Take a close look at the physical and MAC layers of LTE-based C-V2X to learn its advantages over other generations of V2V protocols, and examine how security is (and is not) built into C-V2X standards. Optionally, study how commercial C-V2X implementations build on basic C-V2X standards with application-layer security and data exchange protocols. Estimated completion time: 60-75 minutes (75-90 minutes with optional activity).

V2Verifier Testbed


V2Verifer is an open-source software-defined radio (SDR) testbed for studying security problems in vehicle-to-vehicle (V2V) communications. V2Verifier features the first open-source implementation of the IEEE 1609.2 standard for V2V security, with features including V2V message signing and verification as well as privacy-preserving pseudonymous identification. Support is also included for WAVE Short Message Protocol (WSMP) based on the IEEE 1609.3 standard. At the lower communication layers, V2Verifier supports both major V2V protocols, Dedicated Short Range Communication (DSRC) and Cellular Vehicle-to-Everything (C-V2X).

Targeted Discreditation Attack Against Trust Management in Connected Vehicles

This video describes how our vehicle-to-vehicle (V2V) security testbed, V2Verifier, can be used to identify security flaws in V2V technology. We briefly introduce V2Verifier, then we introduce and experimentally validate a novel reactive jamming attack against a major V2V protocol. This presentation was originally given at IEEE ICC 2021.


Evaluating V2V Security on an SDR Testbed

An introduction to V2Verifier, our software-defined radio (SDR) testbed for secure vehicle-to-vehicle (V2V) communication. We describe the motivation and architecture of V2Verifier, demonstrate how V2Verifier can be used to experiment with attacks against V2V protocols, and show how V2V security standards (IEEE 1609.2) can effectively mitigate certain types of attacks against V2V. This presentation was originally given at the Computer and Networking Experimental Research using Testbeds (CNERT) workshop held in conjunction with IEEE INFOCOM 2021.
