Authentication method and system based on fog computing and used for enhancing communication security

Abstract

The invention discloses a method and system based on a fog computing framework and used for enhancing communication security. The system comprises an endpoint as well as an identity authentication security module, a lookup table module, a suspicious MAC address isolation account book module and a private key storage module among nodes; and by virtue of a decentration authentication mechanism, security authentication is performed on the endpoint as well as identities among the nodes, and a machine learning method is adopted for enhancing the communication security between the nodes and the endpoint as well as between the nodes, so as to prevent a malicious attack and a fake identity. By adopting the technical scheme of the invention, extra time and bandwidth consumption produced by a third-party organization can be avoided, and processing efficiency of a cloud terminal and a local fog node is improved; and authentication accuracy is improved, and establishment of a more timely securityprecaution mechanism can be facilitated.

Description

technical field [0001] The invention belongs to the fields of encryption authentication technology, Internet of Things security, and fog computing technology, and relates to identity confirmation between nodes and endpoints and an enhancement method for communication security mechanisms, in particular to an enhanced node-to-endpoint and node-to-node based on a fog computing framework A method and system for communication security between. Background technique [0002] The concept of fog computing was proposed in 2011, and then the OpenFog Consortium (OpenFog Consortium) made a clear definition of fog computing: fog computing is a system-level horizontal Computing, storage, control, and network resources and services anywhere in the region support multiple vertical industries and application areas, deliver wisdom and services to users and businesses, and make services and applications distributed closer to the physical level. Fog computing The structure extends from things, ...

Just imagine that in an intelligent transportation system, if there are malicious users pretending to be nodes to send a large amount of false information, it will inevitably cause confusion in traffic signals, and even casualties; If the other machines in the machine transmit wrong information, it will lead to the delay of the production process and the waste of raw materials, resulting in a lot of time and money loss
