Vehicular ad-hoc network is an exciting study that aims to improve driver safety in driving. Vehicle-to-vehicle (V2V) is communications between vehicles that occurs on a VANET using wireless channels. This channel allows vehicles to share personal or safety information with other vehicles. Vehicle communication is potentially vulnerable to adversaries' security attacks that can harm the driver and other legitimate users. Therefore, it requires a high-security system. This research proposes a

Our research focuses on obtaining a symmetric key that has a high key formation speed (KFS) with a low-key discrepancy level (KDL), while still thinking about the randomness and ensure safety from passive attackers. In the pre-processing, we use a combination of Kalman Filter and Polynomial Regression by modifying the parameters to produce the best performance. We also modified the grey code in the Modified Multibit (MMB) Quantization method to reduce the quantization bit mismatch. Our approach to the MAPI scheme can assign symmetric keys with better performance than existing schemes, increasing KFS and decreasing KDL up to 100%. Moreover, the scheme can generate a symmetric key that deals with NIST's statistical tests.

INTRODUCTION In recent years, the vehicle ad-hoc network (VANET) is one of the most promising researches along with the development of the vehicle industry and wireless communication technology. VANET is part of a mobile adhoc network (MANET), which refers to an ad-hoc network that provides communication over a wireless network [1]. There are 2 kinds of communication on VANET, such as Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communications. RSU (Road-Side Unit) is used for infrastructure modules installed along the side of the road, while OBU (On-Board Unit) is a module installed in vehicles [2] . Vehicles exchange messages directly without an intermediary entity due to V2V communication used dedicated short-range communication (DSRC) standard at a frequency of 5.9 GHz [3]. The main application of V2V communication is for safety rides, such as preventing vehicle clashes, obstacle warnings, lane change warnings, and others. by exchanging information with other vehicles [4] . This technology is susceptible to various security attacks, such as falsifying road congestion messages, giving false warnings, delays messages, attacker monitors important data exchanged between authorized parties, attacks network accessibility, and others. Therefore, high-security systems are an essential concern for secure V2V communication. Some security requirements include availability, message authentication and integrity, the confidentiality of the message content, non-repudiation, and privacy protection [5].
