Optimising Data Integrity in VANETs: An Innovative Method to Minimize Replay and Tampering Attacks

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 manipu�lation 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 process�ing 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.
