Abstract

The invention relates to a data security transmission method and system of an electric vehicle connected with an intelligent network and belongs to the field of digital information safety communication, and the method comprises the following steps: counting the number of vehicles in each communication region, and determining whether to establish a mixing region in each communication region or notaccording to the number of vehicles; setting a risk threshold, and judging the risk level of each mixing region according to the risk threshold; wherein the risk levels comprise a first risk level, asecond risk level and a third risk level; determining a communication mode of each mixing region according to the risk level; wherein the communication modes comprise a mixed region anonymous communication mode, a mixed region anonymous and group signature communication mode and a data attribute forwarding communication mode, and the mixed region anonymous and group signature communication mode, the mixed region anonymous and group signature communication mode and the data attribute forwarding communication mode are correspondingly executed on the mixed regions of the first risk level, the second risk level and the third risk level respectively. The security of data transmission is improved, and the privacy security and personal security of users are protected.

Description

technical field [0001] The invention relates to the field of digital information security communication, in particular to a method and system for secure data transmission of an intelligent network-connected electric vehicle. Background technique [0002] With the development of science and technology and the improvement of living standards, intelligent connected electric vehicles, as an intelligent and interconnected mode of transportation, have begun to integrate into our lives.
