Embodiment 1

[0072] For a user who requests to join the edge computing network, the user must first be authenticated, and those who meet the requirements can join as a legitimate user, and the newly joined node is assigned an initial reputation value. When a video processing task request is initiated, the edge server first screens out a list of service-providing users that meet the capabilities of the device according to the task's capability requirements (set each task request to have a suitable service-providing node), and randomly Select an end user to interact with. The interaction is completed and the service is updated based on the interaction results based on the behavioral trust mechanism to provide user reputation values. Each region is deployed with a sufficiently powerful and reliable edge server for node identity information verification and storage, node capability matching, reputation value calculation, Storage, update, query and blacklist management. Such as image 3 A tax...

Embodiment 2

[0134] Such as Figure 5 As shown, this embodiment discloses a trust evaluation device based on subjective logic in edge computing network video processing, including: a trust modeling module, the trust modeling module includes an identity modeling sub-module, a capability modeling sub-module and Behavior modeling sub-module; evaluation module, based on the model established by the trust modeling module, after the interaction is completed, the task request node submits evaluation to the edge server according to the interaction result; update module, the edge server calculates and updates the reputation value of the storage service provider node according to the evaluation result , and notify the service provider node of the updated result.

[0135] Furthermore, the identity modeling sub-module models identity trust, and the specific modeling steps are as follows:

[0136] Only after passing the identity authentication of the trusted central authority (edge ​​server), each edg...

Abstract

The invention discloses a trust evaluation device based on subjective logic in edge computing network video processing, and is characterized in that the trust evaluation device comprises a trust modeling module which comprises an identity modeling submodule, a capability modeling submodule and a behavior modeling submodule; an evaluation module used for submitting evaluation to the edge server bythe task request node according to an interaction result after the interaction is completed according to the model established by the trust modeling module; and an updating module used for calculatingand updating the reputation value of the storage service providing node by the edge server according to the evaluation result and informing the service providing node of the updated result. Through edge node screening of an identity trust mechanism, a capability trust mechanism and a behavior trust mechanism, edge nodes with qualified identities, capabilities and reliable behaviors are ensured tobe added into a network system for service interaction, trust information is shared, evaluation of a local reputation value and a global reputation value is realized, and the safety and the stabilityof the whole edge computing system are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a trust evaluation device based on subjective logic in edge computing network video processing. Background technique [0002] In recent years, with the development of information technology, mobile smart devices have shown an explosive growth trend, and at the same time stimulated the emergence of many new applications, such as virtual reality, augmented reality, mobile interactive games and so on. The emergence of these new applications poses a great challenge to the user experience in the field of mobile computing. Edge computing is a new type of distributed computing architecture, which aims to transfer the control of computing applications, data and services from certain central nodes of the Internet. (“Core”) to move to the other logical extreme (“Edge”), adjacent to mobile smart devices as well as end users. In the edge computing network, various infrastructures with dif...
