Poster Abstract: Privacy-preserving Control Message Dissemination for PVCPS

Abstract:
Privacy preservation is critical for control information dissemination in Platoon-based Vehicular Cyber-Physical Systems (PVCPS). However, the vehicular communication is vulnerable to wireless eavesdropping attack and message modification, due to broadcast nature of radio channels. In this poster, we present a secret key generation testbed for PVCPS security, which is built based on off-theshelf autonomous robotic vehicles and TelosB wireless transceivers. A cooperative secret key agreement (CoopKey) scheme is demonstrated for encrypting/decrypting the disseminated control messages. To unify the secret key generated by the vehicles, CoopKey explores received signal strength (RSS) measurements and channel estimation on the inter-node radio channel. In addition, a Pythonbased user interface is also implemented to show real-time bit mismatch rate of CoopKey.
