Thesis Title Security in Vehicular Networking Kastuv M. Tuladhar VANETs Why VANETs Security is important ? Introduction Autonomous Vehicles VANETs Security ⋆ Vehicles have to share its information to infrastructure or other vehicles Certificate Revocation List (V2X) in an open wireless medium. Definition Motivation ⋆ VANET applications contains the exchange of messages such as Proposed Scheme Evaluation emergency, traffic conditions, road accidents that requires the data Secret Key Distribution communication between the nodes. Motivation ⋆ The message content can have impact on the drivers’ actions to the System Model Proposed Scheme vehicle. Evaluation Future Works Presence of Malicious Node Summary/Goals Conclusion Thanks ⋆ Malicious node can spread fake information (position/speed/accident) to take advantage of short routes or may have bad intention.
Thesis Title Real World VANET attacks Kastuv M. Tuladhar VolksWagon RKE Hack VANETs Introduction Autonomous Vehicles VANETs Security ⋆ In USENIX Security 2016, Garcia et al. present that only 4 encryption Certificate Revocation List keys are universally used over 100M vehicles produced by VW group over Definition Motivation the 20 years. Proposed Scheme Evaluation Fiat Chrysler Automobiles(FCA) hacked Secret Key Distribution Motivation System Model ⋆ FCA Jeep Cherokee “remotely” controlled by Charlie Miller and Chris Proposed Scheme Evaluation Valasek. ⋆ On 7/24/2015, FCA issued a recall to 1.4M vehicles. Future Works Summary/Goals Tesla hacked Conclusion Thanks ⋆ On 2016, team of hackers take remotely controlled Tesla Model car for 12 miles.
Thesis Title Real World VANET attacks Kastuv M. Tuladhar VANETs Introduction “Cars are already insecure, and you’re adding a bunch of sensors and Autonomous Vehicles VANETs Security computers that are controlling them...If a bad guy gets control of that, Certificate it’s going to be even worse.” -Miller (Security Specialist) Revocation List Definition Motivation Proposed Scheme Evaluation Secret Key Distribution Motivation System Model Proposed Scheme Evaluation Future Works Summary/Goals Conclusion Thanks

Thesis Title Public Key Infrastructure (PKI) Certificate Kastuv M. Tuladhar How to secure VANETs ? VANETs Introduction Autonomous Vehicles ◮ Private keys are used to cryptographically sign messages that can be VANETs Security authenticated using the matching public key. Certificate Revocation List ◮ Public key certificates are used for authentication to prevent Definition Motivation attackers from causing harm. Proposed Scheme Evaluation ◮ Cryptographically signed messages also provide message integrity; any Secret Key Distribution changes to the message will cause signature verification to fail. Motivation ◮ Certificates have a validity time period. System Model Proposed Scheme Evaluation Elliptic Curve Digital Signature Algorithm (ECDSA) Future Works Summary/Goals Conclusion ◮ The encryption algorithm specified for use in VANETs by IEEE Thanks Standard 1609.2 is elliptic curve encryption ECDSA. ◮ Both 224-bit and 256-bit key sizes are allowed in the standard.
