Network security protection method based on edge cloud system

Abstract

The invention provides a network security protection method based on an edge cloud system. The method comprises the following steps: performing symmetric encryption on a command issued to an edge computing server by a cloud computing platform through an encryption algorithm, and performing digital signature on the command issued to the edge computing server by the cloud computing platform and an identity identifier of the cloud computing platform through a Hash algorithm; the reply uploaded to the cloud computing platform by the edge computing server is symmetrically encrypted through an encryption algorithm, and the reply uploaded to the cloud computing platform by the edge computing server and the identity identifier of the edge computing server are digitally signed through a Hash algorithm; a security server is established for communication between the edge computing server and the Internet of Things equipment, and the security server distributes different secret keys for communication between different Internet of Things equipment and the edge computing server. According to the invention, secure communication between the edge computing servers and between the edge computing servers and the Internet of Things equipment is realized, and the network security of the system is guaranteed.

Description

Technical field [0001] The present invention relates to the field of network security technology, and more particularly to a network security method based on edge cloud systems. Background technique [0002] In recent years, with the rapid development of all things and wireless communication technology, the number of devices on the edge side of the network and the amount of data generated are rapidly increased. In this context, traditional cloud computing models have problems with poor real-time sex, short bandwidth, high energy consumption and adverse privacy protection, so the edge calculation model calculated by mass data generated by the edge device has become a mainstream resolution. Program. [0003] Objects of edge computing operations include downlink data from the cloud computing platform and uplink data from the Internet of Things devices, so there is a number of interactive communication between edge computing servers, cloud computing platforms, and Internet access dev...

AI Technical Summary

Problems solved by technology

However, the current edge cloud system in the prior art lacks the corresponding network security technology to ensure the communication security between the cloud computing platform and the edge computing server and between the edge computing server and the IoT device

If a network attacker attacks the communication between the cloud computing platform and the edge computing server and tampers with the tasks issued by the cloud computing platform, the system will not be able to process the tasks in real time, seriously affecting the work efficiency of the system; Forging the reply of the edge computing server will cause the system to be unable to further complete the assignment and processing of tasks

If a network attacker launches an attack on the communication between the edge computing server and the IoT device, the system will get wrong perception information, which will seriously affect the system's decision-making and response, causing serious and irreparable losses
