AI Technical Summary

Technical Problem

In existing IoT data transmission solutions, the encryption responsibility of long-link nodes is unevenly distributed, resulting in overall security relying on a single node. Furthermore, security collapses rapidly when a node fails, and there is a lack of multi-node collaborative defense mechanisms.

Method used

By quantifying the trusted participation weight of nodes through a preset evaluation model, dividing functional roles and performing key fragmentation, reconstructing the transmission path in real time, and utilizing multi-node collaborative execution of fragmentation superposition and consistency verification, dynamic security defense is achieved.

Benefits of technology

This approach enables multiple nodes to share the responsibility for encryption, enhancing the system's security and resistance to attacks. It also dynamically adjusts the transmission path to balance high timeliness and security redundancy, thus solving the problem of a sharp drop in security caused by a single point of failure.

Abstract

This invention relates to the field of data transmission technology and discloses a multi-node joint encryption data transmission method based on the Internet of Things (IoT). The method includes: obtaining real-time environmental parameters of candidate nodes in a long IoT link through a preset evaluation model, quantifying them into trusted participation weights, link availability weights, and service timeliness priority weights; assigning functional roles to candidate nodes based on the trusted participation weights, classifying them into core sharding bearer nodes, auxiliary verification nodes, threshold nodes, or pure forwarding and transparent transmission nodes. This invention employs a multi-dimensional weight-driven asymmetric assignment of functional roles and a threshold sharding joint encryption scheme, achieving the technical effect that encryption responsibility is jointly borne by multiple nodes in a long link. This realizes a leap from single-point protection to full-link collaborative defense of the security boundary, solving the shortcomings of existing technologies where security drops sharply after a node fails due to the non-participation of forwarding nodes in joint processing.
