Utilizing RSS-ratio for implementing anonymous communications in VANETs (Digest Paper)

As vehicles meet each other occasionally in VANETs, users will naturally have the requirement of protecting their privacy during VANET communications. The privacy requirements bring unique challenges for the communication setup and maintenance as any information (such as IP address and MAC address) that may relate to the users' IDs should not be used. To resolve this problem, we propose to utilize the dynamic physical level information, RSS-Ratio, as the address. This short paper briefly presents why RSS-Ratio can be used as an address while not revealing users' IDs, and our proposed method of utilizing RSS-Ratio for anonymous connection setup and maintenance.
