摘要: |
基于Ad Hoc网络的车载移动通信网(VANET)由于网络基础的原因,以及VANET自身的特点,带来了很多安全的问题。根据VANET的特点,对VANET进行自顶向下的分层,并针对物理层的攻击进行总结和归纳,再利用现有技术对其中一些攻击给出应对措施。底层的物理层安全的保证对整个VANET的安全至关重要。 |

Abstract: |
Due to the network infrastructure and its own characteristics,the vehicular Ad Hoc networks(VANET) have brought a lot of security problems.According to the characteristics of VANET,VANET is hierarchized in top-down approach,then the attacks in physical layer are summarized and the appropriate response measures for some of these attacks are proposed using available technologies.As the bottom layer,the security of physical layer is critical for VANET security. |
