Cluster based key management in VANET networks

Vehicular networks VANET announce as the communication networks of the future, where the mobility is the main idea. These networks should be able to interconnect vehicles. The optimal goal is that these networks will contribute to safer roads and more effective in the future by providing timely information to drivers and concerned authorities. They are therefore vulnerable to many types of attacks. Their success will undoubtedly confidence they bring to their users. The Traditional model does not meet with the new requirements of such networks where the characteristics resemble more of social models. In this paper, we present the various solutions proposed by different research teams working on the distribution of certificates and our proposal to adopt a new method of distributing certificates in VANET.
