Vehicular ad hoc networks are emerging as an effective technology for providing a wide range of safety applications to by-vehicle passengers. Ensuring secure operation is one of the prerequisites for deploying reliable VANETs. In this article we argue that public key infrastructure is the most viable mechanism for securing VANETs as it can meet most VANET security requirements. However, PKI cannot...
The chain-reaction collision caused by a sudden event such as deer-vehicle collision is a serious accident in highway traffic. By propagating the authenticated emergence message on deer-vehicle collision with vehicle-to-vehicle (V2V) communication, the chain-reaction accident could be mitigated. However, the long delay imposed by traditional signature based authentication may weaken the effectiveness...
Searching for a vacant parking space in a congested area or a large parking lot and preventing auto theft are major concerns to our daily lives. In this paper, we propose a new smart parking scheme for large parking lots through vehicular communication. The proposed scheme can provide the drivers with real-time parking navigation service, intelligent anti-theft protection, and friendly parking information...
With the adoption of state-of-the-art telecommunication technologies for sensing and collecting traffic related information, Vehicular Sensor Networks (VSNs) have emerged as a new application scenario that is envisioned to revolutionize the human driving experiences and traffic flow control systems. To avoid any possible malicious attack and resource abuse, employing a digital signature scheme is...
