Access point decision-making method under the SDN-based space-ground integrated network authentication architecture

Abstract

The invention discloses an access point decision-making method based on an SDN-based space-ground integrated network authentication framework. The method includes: screening access points to generate a candidate access point set; standardizing processing samples; obtaining an attribute weight matrix; using TOPSIS, The RSR algorithm evaluates the candidate access points; weights the two evaluation results, and arranges the candidate access point samples in descending order according to the weighted results; selects the first n candidate access point samples as the access point samples according to the number n of access requests. entry point. The present invention introduces SDN into the access authentication process in the space-ground integrated network scenario, improves the efficiency and success rate of access authentication by optimizing the selection method of the access point, and combines the two evaluation methods so that the original data information is not lost It avoids the interference of outliers in certain situations, and at the same time expands the scope of use, making access point decision-making more scientific and comprehensive. By comprehensively considering multi-dimensional attributes and selecting the most ideal access point, access efficiency and resource utilization can be effectively improved.

Description

technical field [0001] The invention belongs to the field of software engineering, and in particular relates to an access point decision-making method under an SDN-based space-ground integrated network authentication framework. Background technique [0002] The space-ground integrated network is a highly heterogeneous network formed by the fusion of satellite networks, terrestrial networks and other networks. In recent years, satellite technology has developed rapidly and vigorously, and the communication needs of various mobile devices have continued to increase. The space-ground integrated network has important value in military and civilian applications. It not only conforms to the trend of future technological development, but also is a major strategic demand of China. Therefore, it is of great strategic significance to study the security technology under this network. However, the space-ground integrated network has the characteristics of limited node capabilities, ope...

But they did not take into account the optimization of the access point selection strategy in the access authentication process

[0004] However, most of the existing access authentication and handover authentication technologies study the key agreement mechanism from the perspective of cryptography, and seldom consider it from the perspective of authentication architecture and selection of access points.

And most of the schemes only consider the requirements of a single scenario or only make decisions around a single indicator, with low mobility and universality
