Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cybersecurity methods, whether hardware-based or software-based, face limitations in flexibility and resource efficiency, failing to effectively and quickly control network packet security in digital environments.
Innovation Solution
A system comprising a network card, driver, network accelerator with a data layer and man-in-the-middle attack tool, and a TCP/IP model within the operating system's first space, which parses and filters malicious packets, reducing data volume for the TCP/IP model and ensuring secure communication with the application layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based detection is used, then detection reliability is improved, but flexibility and configurability deteriorate
Solution Approach 1:
The patent introduces a security gateway as an intermediary component between the network card and the TCP/IP model. This gateway acts as a mediator that provides both reliable detection (through its filtering functions) and flexibility (through configurable rules), resolving the contradiction by neither being purely hardware nor purely software but a hybrid intermediary layer.
2Adaptability or versatility
If purely software-based detection is used, then flexibility is improved, but resource limitations worsen
Solution Approach 1:
The patent segments the network packet processing function into multiple parts: the security gateway handles security filtering separately from the main TCP/IP processing stack. This segmentation allows the system to maintain flexibility in security rules while reducing the resource burden on the main processing system, as the gateway can filter packets before they reach the resource-intensive TCP/IP model.
Solution Approach 2:
The security gateway performs preliminary filtering of network packets before they are processed by the main TCP/IP protocol stack. By performing this preliminary action, the system reduces the volume of data that requires intensive software processing, thereby conserving computing resources while maintaining the flexibility of software-based security rules.
3Ease of manufacture
If conventional security detection is used, then implementation simplicity is improved, but processing speed deteriorates
Solution Approach 1:
The security gateway serves as an intermediary that simplifies implementation by providing a dedicated security processing layer with built-in filtering capabilities. This intermediary approach maintains implementation simplicity while improving processing speed, as the gateway can efficiently filter packets using optimized data structures and algorithms before passing them to the main processing stack.

AI summary
Various embodiments of the teachings herein include a method for improving cybersecurity. An example includes: parsing a network packet to obtain a first network packet, wherein an operating system reads content in the first network packet sent by a controller for controlling operation of a first device; parsing attributes of the first network packet; filtering out malicious packets from the first network packet based on attributes of the first network packet, to obtain a second network packet; parsing the second network packet to establish communication with a first application layer in a second space of the operating system; and performing data conversion on the second network packet to enable the first application layer.
