Symmetric Key Generation Use Received Signal Strength for V2V Communication

This paper proposes a symmetric key generation scenario to secure information on V2V (Vehicle-to-Vehicle) communications. This research uses the Raspberry Pi 3 as an OBU (On-Board Unit), which is installed on each vehicle. The key generation mechanism uses the Ad-Hoc network to get the RSS (Received Signal Strength) value between two communicating vehicles for further processing to produce an equivalent key between vehicles. The key that has been generated is used to secure the information so that it cannot be captured or stolen by others. When retrieving RSS data, various speed and ping time interval scenarios are used to see system performance. Based on the test results, it can be seen that the Kalman Filter can increase the correlation of RSS data up to 0.967. The resulting key can produce the highest KGR of 9.600 bit/s, and the KDR in all scenarios can reduce to 0%.
