Solution Overview
Problem
The diverse and large volume of data collected by interconnected IoT nodes poses challenges in uniform data transmission capabilities, network positions, communication protocols, and resource availability, making it difficult to securely transmit sensitive information across the network.
Innovation Solution
Implementing nodes with dual network access ports, including a dedicated network access port for time-sensitive instructions and a pass-through network access port for relaying data, which allows for prioritized and secure data transmission by utilizing port partitioning techniques and reconfigurable channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If nodes use a single shared network access port for all data transmission, then device complexity is reduced, but data transmission security and reliability deteriorate due to inability to prioritize sensitive information and vulnerability to Man-In-The-Middle attacks
Solution Approach 1:
The network access port is segmented into multiple virtual channels (first network access port and second network access port) that operate independently. Each channel can be assigned different security protocols and priorities, allowing sensitive data to be transmitted through a dedicated secure channel while non-sensitive data uses another channel, thereby resolving the contradiction between simplicity and security.
Solution Approach 2:
The system dynamically assigns data to different network access ports based on data sensitivity and transmission requirements. The network access ports can be reconfigured and reassigned in real-time, providing adaptive security measures that respond to changing threat landscapes and data priorities without requiring permanent complex hardware configurations.
2Ease of operation
If nodes use a single shared network access port, then ease of operation is improved, but data transmission efficiency and latency performance worsen due to inability to prioritize time-sensitive instructions
Solution Approach 1:
The network access port is divided into multiple virtual channels with different priority levels. Time-sensitive instructions are assigned to high-priority channels that are processed first, while non-time-critical data uses lower-priority channels. This segmentation enables efficient data transmission without requiring complex manual configuration, as the system automatically routes data based on priority markers.
Solution Approach 2:
The system changes the operational parameters of network access ports by creating virtual channels with different priority levels, transmission protocols, and bandwidth allocations. This allows the same physical port to handle multiple types of data traffic with different requirements simultaneously, improving overall transmission efficiency without adding physical complexity.
3Adaptability or versatility
If nodes have diverse data transmission capabilities and resource availability, then adaptability of the IoT network is improved, but uniformity of data transmission protocols and security standards deteriorates, making secure transmission difficult
Solution Approach 1:
The network access port design provides universal functionality by implementing multiple virtual channels that can accommodate different data types, security requirements, and transmission protocols within a single port structure. This allows nodes with diverse capabilities to communicate uniformly through standardized channel interfaces while maintaining the flexibility to handle specialized data requirements, thus achieving both adaptability and uniform security standards.
Solution Approach 2:
Different virtual channels within the network access port are assigned different security protocols and transmission characteristics based on local requirements. Sensitive data channels can implement encryption and authentication, while non-sensitive channels use simpler protocols. This local quality approach allows each channel to be optimized for its specific purpose while maintaining overall system uniformity through the common port architecture.

AI summary
Apparatus and methods are provided for improving the security and transmission of data carried by an Internet of Things (“IOT”) network. Each node on the IoT network may include a pass-through network access port and a dedicated network access port. The dedicated network access port may be used by the node intermittently to transmit/receive a first class of data. The pass-through network access port may be used continuous by the node to transmit/receive a second class of data. The dedicated network access port may transmit/receive data using a first transmission channel that is physically or virtually isolated from a second transmission channel that is used by the pass-through network access port. Providing isolated transmission channels may improve the security of data transmitting using the dedicated network access port.
