随着虚拟局域网的发展，安全性在系统设计中占有重要的地位。由于虚拟局域网中通信的不可靠性，安全协议需要更多的考虑，如隐私，认证和消息的一致性。然而，效率一直被忽视之前，因为以前的方法会产生显着的通信开销。在本文中，我们提出了一种新的安全方案，名为对称伪装安全方案（SMSS），它可以达到安全要求，同时保持低的系统开销。在SMSS中，我们关注的是车辆到车辆的通信，这是典型的场景之一，在VAN。该方案采用对称加密保证消息的一致性，采用局部匿名保护隐私，采用预共享密钥实现认证。本文对该方案进行了详细的描述，并与PKI安全方案进行了性能比较。
Security plays an important role in the system design with the development of VANETs. Because of the unreliable communications in VANETs, security protocols need more considerations, such as privacy, authentication, and consistency of messages. However, efficiency has been overlooked before, because previous methods incur significant communication overhead. In this paper, we propose a novel security scheme, named Symmetric-Masquerade Security Scheme (SMSS), which can achieve the security requirements while keeping a low system overhead. In SMSS, we focus on the vehicle-to-vehicle communications, which is among the typical scenarios in VANETs. The symmetric encryption is employed in our scheme to ensure the consistency of the messages, the local pseudonyms are equipped to protect the privacy, and the pre-shared keys are introduced to implement the authentication. This paper makes a detailed description of the novel scheme, then analyzes its performance in comparison with that of the PKI security scheme.
