<p>A Vehicular Ad Hoc Network (VANET) technology is becoming one of the most advanced technologies; however, the major barrier it faces is to keep the information secure and to improve its confidentiality. Recently, there have been some methods proposed to keep the information safe and implement the reliable platform for information transmission. However, based on the attacks varieties, and the way they are changing their approach, makes the system still insecure against some certain attacks. To overcome the vulnerability under the eavesdropping attack, we propose a solution to minimize the eavesdropping risk and protect the communication between vehicle and server. The solution can be considered as adding the road side unit (RSU). In fact, RSU is an extra neural network between vehicle and server which does not generate any key; however, it transfers the key from vehicle to the server. In this model, cipher text (encryption) is generated by RSU. In addition, the filters in the convolutional layers are used for encrypting the messages and to protect it against eavesdropping efficiently. We formally verify the security functionality of the solution scheme by training the neural networks based on different parameters. Analysis shows that our proposal has a strong ability to prevent eavesdropping attack.</p>

“…According to the research done by Ajay N et al [21], the attackers are able to send the messages to the vehicles frequently to make the buffer full; therefore, vehicles would not be able to receive the further messages which might be vital. This attack can be classified as the most dangerous one in a VANET system.…”

“…With the aid of C and a, the vehicle computes a symmetric key S which will be used to securely exchange authentication messages between the vehicle and TA. This symmetric key is calculated by (9). After the generation of the shared key S, the vehicle splits this key into two separated sub-keys: S 1 and S 2 to be utilized in further computations.…”

“…The protocol uses low-level computing operations such as XOR operator and hash functions, but the certificate management is its main demerit. Moreover, a secure authentication protocol is introduced in [9] to successfully achieve the data confidentiality between the vehicle and infrastructure, but the secure channels are required for exchanging keys. Besides, the proposed scheme in [10] utilizes long-term certificate for each entity in the network to revoke the vehicle identity in the case of attack.…”

It is crucial to support emergency applications provided by vehicular adhoc network (VANET) through enabling vehicles to quickly access to the infrastructure and consequently request rescue services. Additionally, the communication channels between vehicles and the infrastructure lack various security features due to the inferior wireless characteristics of their environment. However, most of the existing authentication schemes which are used to fix the security drawbacks lead to heavy computations and large storage burdens on the vehicle onboard unit (OBU). These schemes utilize secure channels while distributing the network parameters between the various participants. Yet, it is not efficient to establish secure channels during the interactions between entities. Furthermore, lightweight cryptography is an efficient security solution which is adequate for OBU to maintain a reasonable efficiency with low computational and communication costs. Two basic demerits for lightweight authentication protocols are highlighted as follows: Firstly, symmetric key-based authentication protocols dismiss achieving non-repudiation feature, leading to several security attacks in VANET. Secondly, public key-based authentication schemes are relied on elliptic curve cryptography (ECC) which makes the protocol implementation more difficult. Hence, this paper introduces a novel authentication protocol that utilizes Chebyshev chaotic maps to secure connectivity between the vehicles and infrastructure without using secure channels to distribute the network parameters. The new protocol combines the concept of the symmetric key cryptography with the public key signature to satisfy both the lightweight property and non-repudiation feature. Thus, this protocol introduces a novel network model which is the lowest hardware complexity, compared with others. The performance analysis is performed by Wolfram Mathematica, proving that the proposed protocol is superior in terms of security and performance aspects; its computation and storage costs of OBU are enhanced with 24.09% and 16.99%, respectively, compared to the most competing scheme. Besides, the Scyther simulation confirms the security of the protocol.
