An advanced security scheme based on clustering and key distribution in vehicular ad-hoc networks

- We improve security in VANETs using the technique called Secure scheme based on Clustering and Key Distribution (SCKD).
- SCKD uses clustering in order to scale the network and to reduce overhead and number of saved keys.
- SCKD monitors malicious vehicles and chooses cluster-heads from the trustiest vehicles.
- SCKD uses clustering and key distribution, but reduces cost and time of key generation and distribution.
- SCKD preserves authentication, confidentiality, data-integrity, non-repudiation, and unforgeability.
