Embodiment Construction

[0073] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0074] Such as figure 1 As shown, a kind of vehicle-mounted ad hoc network security authentication method based on Cuckoo filter of the present invention is divided into 2 layers: the top layer is the national credible institution TA, which is connected with RSU through a safe channel; the bottom layer has RSU and vehicle (or OBU) Composition, the communication between them is based on the dedicated short-range communication (DSRC) protocol; TA is always online, credible, and never compromised, TA can uniquely confirm the true identity of the vehicle; RSU is credible, compared to OBU, With higher computing power.

[0075] Such as figure 2 As shown, a kind of vehicle-mounted ad hoc network security authentication method based on Cuckoo filter of the present invention has two steps, are respectively: ...

Abstract

The invention discloses a vehicle-mounted self-organizing network security authentication method based on a Cuckoo filter, which includes two steps in sequence: (1) identity authentication between the vehicle and the infrastructure (V2I), specifically including system initialization, initial handshake, and message signature (2) vehicle-to-vehicle (V2V) identity authentication, specifically including three processes of group key generation, group message signature and group message authentication. The present invention is based on software implementation and does not depend on any special hardware equipment; in the authentication stage, the method of non-bilinear pairing is used, and this non-bilinear pairing verification method is not only applicable to V2I, but also applicable to V2V verification, with efficient calculation Capability and low overhead cost, the technique of inserting Cuckoo filter and binary search in the batch authentication stage can retrieve whether the signature is valid, which greatly improves the efficiency of the verification stage.

Description

technical field [0001] The invention relates to the field of vehicle network communication security, in particular to a Cuckoo filter-based vehicle ad hoc network security authentication method. Background technique [0002] VANETs is a self-organizing network consisting of interrelated vehicles, the main purpose of which is to ensure the safety and convenience of drivers and passengers. The function of each car is equivalent to a router, which can transmit information to the outside world through wireless communication equipment. A typical VANETs has two node types, one is the mobile communication node pre-installed on the vehicle, On-Board Unit (OBU), and the other is the infrastructure deployed on both sides of the road on a large scale, Road Side Unit (RSU). [0003] Communication in VANETs is divided into two types, vehicle-to-vehicle communication (V2V) and vehicle-to-infrastructure communication (V2I), and these two types of communication are controlled by a short-ra...
