Safe and efficient data forwarding system and forwarding method in vehicle named data network

Abstract

The invention discloses a safe and efficient data forwarding system in a vehicle-mounted named data network and a forwarding method thereof, including a forwarding strategy and a safety strategy. By combining vehicle position information and roadside units, efficient and reliable data forwarding can be realized, and the vehicle can be automatically forwarded. To organize the data integrity verification and access control in the named data network, the whole process adopts an anonymous method to ensure data security, and at the same time, it is realized through the proxy re-encryption technology, and the calculation overhead is transferred to the vehicle end. Finally, in order to ensure the practicability of the present invention , which provides a vehicle incentive mechanism. The forwarding strategy in the present invention can reduce the delay of the vehicle network and increase the data throughput, and the security strategy ensures the security requirement of the vehicle self-organizing network.

Description

technical field [0001] The invention relates to a data safe forwarding technology, in particular to a safe and efficient data forwarding system and a forwarding method in a vehicle named data network. Background technique [0002] With the increasing popularity of the concept and application of "vehicle network", vehicle ad hoc networks are more and more widely used to improve road conditions, improve traffic safety conditions, and provide in-vehicle entertainment information transmission services for passengers and drivers. However, due to the high-speed mobility of the vehicle ad hoc network, the movement of vehicles and obstacles in urban areas may cause frequent connection interruptions and network mutations. Therefore, the traditional IP-based point-to-point communication technology cannot handle the above situation very well, and it will not be able to complete the data transmission task well in the vehicle ad hoc network. [0003] Specifically, consider a scenario wh...

Problems solved by technology

However, existing schemes rely on peer-to-peer communication and static neighbor relationships, so this scheme is not suitable for vehicle named data network systems with dynamic characteristics

[0012] In general, there are more or less defects in the existing related technologies, such as: frequent interruption / mutation of network connections in vehicular ad hoc networks, and the inability to guarantee efficiency and security during data forwarding, etc.
