Power terminal cloud edge-end cooperative security access authentication method based on edge computing

Abstract

The invention relates to access authentication of power terminal equipment, and aims to provide a power terminal cloud edge-end cooperative security access authentication method based on edge computing. The method comprises one-time authentication when the power terminal is accessed and continuous authentication after the power terminal is accessed, wherein the one-time authentication is jointly participated by the power terminal, the edge device and the cloud platform, and the continuous authentication is only participated by the power terminal and the edge device. According to the invention, a continuous authentication link is introduced to enhance security, and a lightweight identity authentication mechanism is realized by a password and non-password means. According to the method, mechanism design is carried out by using the white list, the digital signature and the challenge response, so that feasibility is guaranteed; in terms of security, one-time complex authentication is considered to fully ensure access security during access, and continuous simple authentication after access is used as a supplement to improve the security; and the advantages of edge calculation are fully played in conciseness, and a simple authentication mechanism is selected to reduce calculation pressure.

Description

technical field [0001] The invention relates to access authentication of power terminal equipment, belongs to the field of information security, and aims to provide a method for secure access authentication of power terminal cloud-edge-terminal collaboration based on edge computing. Background technique [0002] With the continuous development of the power distribution Internet of Things, a large number of power distribution terminals are connected, and it is imperative to deploy edge computing devices. By deploying edge nodes on the data source side, edge computing can process data in a timely manner, effectively relieving the computing pressure brought by centralized data processing, and speeding up data processing efficiency while reducing network transmission bandwidth consumption. With the addition of edge nodes, the traditional "cloud-end" access authentication architecture has gradually evolved into a "cloud-edge-end" collaborative architecture. This new architecture ...

Problems solved by technology

[0005] However, the above-mentioned technologies still have deficiencies in feasibility, safety, simplicity, etc.

For example, in the face of the new situation of heterogeneous access authentication requirements for massive terminals in the edge computing environment, the method based on hardware features needs to complete a lot of complicated preliminary work, and is easily restricted by environmental conditions; simple asymmetric encryption means authentication in security The blockchain technology is still in the development stage, and the application cannot be deployed immediately; the trusted computing cannot meet the requirements in terms of simplicity; the calculation requirements of the deep learning method are too large, and the current identification accuracy is insufficient; the secret sharing scheme is High requirements on communication bandwidth, and the calculation consumption is not small
