The possibility of VANET risk to replay and manipulation attacks, which may compromise the security of safety-critical signals, creates a major threat to road safety. Most of the cryptographic methods are used in current security measures, which are either computationally costly or at risk of attacks. By using hash chains and digital signatures in combination to prevent replay and manipulation attacks, and in this research, we provide a unique method for improving the security of data in VANET. We plan to reduce communication delay and processing overhead to ensure message integrity and authenticity is there. Test outcomes demonstrate how well our method identifies and stops replay and manipulation incidents of assault. Our proposed method provides a practical way to protect VANET and ensure the reliability of applications that are essential for safety.

摘要

The possibility of VANET risk to replay and manipulation attacks, which may compromise the security of safety-critical signals, creates a major threat to road safety. Most of the cryptographic methods are used in current security measures, which are either computationally costly or at risk of attacks. By using hash chains and digital signatures in combination to prevent replay and manipulation attacks, and in this research, we provide a unique method for improving the security of data in VANET. We plan to reduce communication delay and processing overhead to ensure message integrity and authenticity is there. Test outcomes demonstrate how well our method identifies and stops replay and manipulation incidents of assault. Our proposed method provides a practical way to protect VANET and ensure the reliability of applications that are essential for safety.
