Due to the proliferation of technology in different areas of daily life, many new types of communication networks are emerging. Among the most interesting wireless networks, Vehicular Ad-hoc Networks are remarkable because road safety and traffic efficiency are two advances that any developed society should undertake. Therefore, research on such networks should evolve to take the final step and move from theory to reality. However, first, it is necessary to improve many aspects related to security. In particular, identification and management of malicious users within the network are major research issues. The traditional method using revocation lists to manage these users becomes very inefficient when the network grows. This paper proposes an alternative method to efficiently manage malicious users, which uses hash trees and query frequencies in order to fit better with the needs of Vehicular Ad-hoc Networks.
