Embodiment 1

[0064] Embodiment 1: An information security distribution method based on policy fusion

[0065] S1. The system initializes the attribute set and the confidence set of the policy maker group.

[0066] The trusted center initializes the attribute set Attr. In this embodiment, there are three attributes attr, which are:

[0067] The attribute name is speed, and the value range is [0km / h, 200km / h], so the speed attribute is "speed: [0km / h, 200km / h]".

[0068] The attribute name is vehicle type, and the value range is [taxi, bus, private car, truck], then the vehicle type attribute is "vehicle type: [taxi, bus, private car, truck]".

[0069] The property name is the road section name, and the value range is [road section A, road section B, road section C, road section D], then the road section attribute is "road section: [road section A, road section B, road section C, road section D1".

[0070] The trusted center initializes the confidence set ρSet of the policy maker group.

Abstract

The invention provides an attribute-based multi-party strategy fusion method in an Internet of Vehicles information distribution scene, and solves the problem that a traffic information service cannoteffectively formulate an appropriate distribution strategy, and the method comprises the following steps: S1, initializing an attribute set and a confidence set of a strategy formulator group by a system; S2, enabling the road side unit to preprocess the strategies formulated by the strategy formulator group and unify strategy formats; S3, enabling the road side unit to screen out conflict sub-policies and non-conflict sub-policies by matching the policies, and unifying the number of attributes in the conflict sub-policies; S4, enabling the road side unit to perform multi-party strategy fusion according to the confidence coefficient of the strategy maker group and the conflict attribute values to form a fusion sub-strategy; S5, enabling the road side unit to merge the non-conflict sub-strategy and the fusion sub-strategy to form a fused access control strategy, performing message encryption according to the access control strategy, and broadcasting encrypted ciphertext information toa message receiver. The method provided by the invention effectively improves the accuracy of information broadcast distribution.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to an attribute-based multi-party strategy fusion method in the information distribution scene of the Internet of Vehicles. Background technique [0002] Vehicle Networking (Vehicular Ad Hoc Network, VANET) is an important branch of the Internet of Things in the field of intelligent transportation, with the main goals of improving traffic safety, improving transportation efficiency, and facilitating people's travel, and has received extensive attention from academia and industry. In the Internet of Vehicles, an appropriate information distribution method is usually used to push service data to specific vehicles, so as to achieve intelligent traffic control, intelligent vehicle control and other purposes. [0003] In the Internet of Vehicles, information distribution in traffic services mainly adopts the form of broadcasting. Due to the open nature of the ...
