AI Technical Summary

Technical Problem

In existing IoT device authentication schemes, behavioral characteristics and multi-factor authentication strategies are disconnected, resulting in static and rigid authentication strategies that cannot adaptively adjust to real-time behavioral risks of devices, leading to security vulnerabilities and low access efficiency.

Method used

A multi-factor dynamic authentication platform is constructed. Real-time behavioral characteristics are acquired through the device behavior acquisition module, and the analysis and matching module converts them into authentication factors. The multi-factor strategy dynamic decision-making module adjusts the authentication strength in real time, and the comprehensive authentication and access control module performs dual evaluation to achieve the synergistic application of behavioral characteristics and multi-factor authentication.

Benefits of technology

It enhances the intelligence and adaptability of IoT security access mechanisms, adjusts the strength of authentication policies in real time, improves security and access efficiency, avoids unnecessary strict authentication of trusted devices, and enhances the ability to continuously perceive and respond to the real-time behavior of devices.

Abstract

This invention relates to the field of Internet of Things (IoT) technology, specifically to a multi-factor dynamic authentication IoT network security access platform. In this invention, a device behavior acquisition module acquires the real-time behavior characteristics of IoT devices requesting access; a behavior feature analysis and matching module performs feature transformation on the real-time behavior characteristics to generate behavior feature authentication factors, and calculates their matching degree with a pre-set legal behavior feature model for first-level authentication judgment; a multi-factor strategy dynamic decision-making module, based on this result, uses the matching degree as a dynamic weight adjustment parameter to adjust the verification strategy strength of other authentication factors in real time and generate a multi-factor authentication strategy; a comprehensive authentication and access control module performs comprehensive authentication based on this multi-factor authentication strategy and combines the behavior feature authentication factors for second-level authentication judgment, thereby controlling network access; this process achieves dynamic adjustment of authentication strategy strength and continuous verification of device behavior.
