An Implementation of Secure Vehicle-to-Vehicle Communication Using Shared Key Generation with Kano Method

Vehicle-to-vehicle (V2V) communication assigned for security and safety in the vehicles communication currently becomes much more interesting, in such it is able to reduce traffic accidents such as collision among vehicles. In this system, the possibility of error shared key when obtaining received signal strength (RSS) between a pair communicating vehicles often occurs. Moreover, the possibility of stealing personal data of drivers and passengers and even controlling take over by adversaries can be happened as well. Hence, in this case, it should have reciprocity without error such that shared key between two participating vehicles is matched. Because attacking activities may happen frequently, thus a security system using shared secret key to protect these personal data in the wireless network should be mandatory. In this paper, a scenario of secure shared secret key generation in V2V communication using Raspberry Pi through 2.4 GHz WiFi connection is implemented. To increase reciprocity, Kalman Filter and BCH error code are adopted. Performance evaluation is evaluated by varying vehicle speed from 20 km/h to 60 km/h with ping time interval from 7 ms to 20 ms. The evaluation result showed that in 20 km/h with 10 ms time interval has the highest correlation 0.99 and the lowest one 0.91 in 40 km/h with 20 ms time interval. Meanwhile, Aono quantization works properly for the scenario 60 km/h with 7 ms time interval for 2881-bit of 3000 data input with key disagreement rate (KDR) 0 in 20 km/h with 10 ms time interval.
