Data security authentication method between cloud and edge node

Abstract

The invention provides a data security authentication method between a cloud and an edge node, and the method provides a bidirectional identity authentication protocol between the edge node and the cloud, can guarantee the authenticity and effectiveness of the identities of the cloud and the edge node, prevents malicious attacks from permeating into a core network, and greatly guarantees the industrial Internet security. According to the method, an elliptic curve cryptographic algorithm is introduced to encrypt key data in an authentication process; the algorithm key size, the system parameters and the storage space are relatively small; operation speed is high, the highest safety intensity per bit is realized; the method is suitable for an authentication environment of edge computing nodes with limited computing resources and storage resources. According to the method, the data plaintext transmission leakage risk is avoided, the replay attack is avoided through the timestamp, the hashiterative operation of the one-time password authentication protocol is simplified, compared with the original authentication protocol, the security is higher, the operation efficiency is also improved, and the authentication security requirement can be met under the environment that the edge node resources are limited.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a data security authentication method between a cloud and an edge node. Background technique [0002] At present, the Industrial Internet has gradually become an emerging industrial application model. Among them, the Industrial Internet platform is an important hub connecting industrial enterprises and user enterprises, which has greatly promoted the intelligentization and efficiency of industrial production, but the centralized cloud processing has intensified Cloud load, born to reduce the cloud load of the industrial Internet platform and edge computing applications. In the edge computing scenario, the edge cloud and edge nodes can process and analyze data nearby, and the cloud is responsible for centralized data processing and storage. Nodes have limited computing resources, complex communication protocols, and insufficient security functions, which can easily...

AI Technical Summary

Problems solved by technology

In the edge computing scenario, the edge cloud and edge nodes can process and analyze data nearby, and the cloud is responsible for centralized data processing and storage. Nodes have limited computing resources, complex communication protocols, and insufficient security functions, which can easily become a springboard for attacks to penetrate into the cloud

In addition, most of the existing industrial communication protocols do not provide authentication functions, which leads to security issues such as identity counterfeiting. This invention is mainly used to solve the two-way identity authentication problem between edge nodes and the cloud to ensure safe and efficient communication between edge nodes and the cloud
