Security is a challenging issue in Vehicular Ad-hoc Networks since entities in the networks generally use insecure channels to communicate with each other, where key agreements are a major challenge. Actually, there exist several security constraints in vehicle to infrastructure communication and vehicle-to-vehicle communications. In this paper, we address open problems related to secure key agreement in Vehicular Ad-hoc Networks by comparing traditional group key agreement protocols with other key agreement protocols.
