Poster Abstract: Privacy-preserving Control Message Dissemination for PVCPS
Ref: CISTER-TR-190203 Publication Date: 16 to 18, Apr, 2019Abstract:
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.
