RAMI: Security System of Information Exchange Based on Shared Key Generation in Vehicle-to-Vehicle Communication

V2V (Vehicle-to-Vehicle) communication is an intelligent transportation system technology that prioritizes driving safety. We propose a system called RAMI that uses the unique RSS (Received Signal Strength) signal strength on a wireless network to generate a shared secret key. We varying testing in speed and of certain ping intervals of time. The correlation of the data obtained from the RSS value is improved by using the Kalman filter. Meanwhile, single-bit quantization with Mathur quantizer combined with Level Crossing is used to suppress the key disagreement ratio (KDR) value. The remaining bit errors will be corrected with the BCH Code, to increase the value of the key generation rate (KGR). To scramble the bits, Universal Hash is used and SHA-256 is used for validation and verification. Triple-DES algorithm works to secure information that will be exchanged between vehicles in the form of latitude and longitude location points. The experimental results show that the practicality of the RAMI system produces a minimum of 4 keys and a maximum of 6 keys generated with an average system time of 11 seconds.
