The invention provides a distributed behavior
authentication method oriented to a computing power network. The distributed behavior
authentication method comprises the following steps: step 1, constructing a feature extractor; the terminals of the computing power network cooperatively
train an identity feature extractor, and the identity feature extractor is applied to each terminal to generate identity credential representation vectors of the terminals; 2, low-
delay sensing deployment is carried out; the regional
cloud server performs similarity calculation on different identity certificates of all the terminals, deploys
authentication services to an edge
authentication server according to needs, and minimizes the
delay time of terminal
mobile authentication; 3, performing multi-stage decision
verification; by applying a
hierarchical clustering algorithm, each
edge server creates a corresponding identity template for each terminal according to the received information, the identity template is composed of a unique identity
label and a corresponding identity
certificate, and a comprehensive decision is made by using the similarity of behavior
modes. The method provided by the invention meets the privacy requirement of the user, and has the characteristics of high authentication performance,
low overhead and
high security.
