论文摘要
不诚实用户的撤销并不是一个容易的问题。本文提出了一种新的方法，以管理使用基于身份的身份验证来通过通过无证书身份验证提高效率和安全性的车辆临时网络中的假名撤销。为了提高撤销列表的性能，本文提出了基于身份验证的动态哈希树木的数据结构，并咨询了吊销假名的频率。使用有关撤销假名咨询频率的知识，可以更轻松地访问最流行的吊销假名，从而损害了最少咨询的吊销假名。因此，该提案在城市环境中尤其有用，在城市环境中，有很多车辆在道路上花费更多的时间，例如公共服务车辆。
Revocation of dishonest users is not an easy problem. This paper proposes a new way to manage revocation of pseudonyms in vehicular ad-hoc networks when using identity-based authentication to increase efficiency and security through certificateless authentication. In order to improve the performance of revocation lists, this paper proposes the use of a data structure based on authenticated dynamic hash k-ary trees and the frequency with which revoked pseudonyms are consulted. The use of the knowledge about the frequency of consultation of revoked pseudonyms allows an easier access to the most popular revoked pseudonyms to the detriment of revoked pseudonyms that are the least consulted. Accordingly, the proposal is especially useful in urban environments where there are vehicles that spend more time on road than others, such as public service vehicles.
