Virtual Manufacturing Screening for Malware in Production Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing systems require significant modifications to detect abnormalities in manufacturing data, and their security measures, such as encryption, become outdated over time, making them vulnerable to cyber attacks and malware infections.
Innovation Solution
A product manufacturing system that includes a manufacture control apparatus, a virtual manufacturing apparatus, and a physical manufacturing apparatus, where the virtual manufacturing apparatus simulates product manufacturing based on held data to detect abnormalities, and a malware detection system that identifies potential malware by virtually manufacturing products and determining abnormalities in the simulation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional abnormality detection systems are implemented to detect manufacturing data abnormalities, then security against cyber attacks is improved, but the existing manufacturing system requires significant modification
Solution Approach 1:
The patent creates a virtual manufacturing system that replicates the functionality of the physical manufacturing system. This virtual copy processes manufacturing data through simulation, allowing abnormality detection without modifying the actual manufacturing equipment. The virtual system serves as a safe environment to test and detect malware and data integrity issues.
Solution Approach 2:
The patent introduces a virtual manufacturing apparatus as an intermediary between the manufacturing data source and the physical manufacturing system. This intermediary layer processes and validates data before it reaches the physical system, enabling security checks without direct modification of existing manufacturing components.
2Reliability
If encryption technology is updated to maintain security over time, then protection against outdated security measures is improved, but the manufacturing system becomes more vulnerable to cyber attacks
Solution Approach 1:
The patent performs preliminary validation of manufacturing data by processing it through the virtual manufacturing system before actual production. This advance checking identifies potential malware and data integrity issues before they can affect the physical manufacturing system, preventing cyber attack exploitation.
Solution Approach 2:
The virtual manufacturing apparatus performs preliminary counter-actions against potential cyber threats by detecting abnormalities and malware in manufacturing data before the data can execute harmful operations on physical equipment. This preemptive detection neutralizes threats in advance.
3Measurement precision
If virtual manufacturing simulation is performed to detect abnormalities, then detection accuracy of manufacturing data issues is improved, but processing time increases
Solution Approach 1:
The patent applies partial validation by focusing the virtual manufacturing simulation on critical aspects of manufacturing data that are most likely to contain abnormalities or malware. Rather than exhaustive checking of all data, the system targets high-risk areas for detection, balancing accuracy with efficiency.
Data Source
AI summary
Provided is a product manufacturing system including: a manufacture control apparatus configured to hold manufacturing data on a product; a virtual manufacturing apparatus configured to virtually manufacture the product by simulation, based on the manufacturing data on the product in the manufacture control apparatus; a physical manufacturing apparatus configured to physically manufacture the product based on the manufacturing data in the manufacture control apparatus; an abnormality determination unit configured to determine whether there is an abnormality in the virtual manufacture of the product by the virtual manufacturing apparatus. When it is determined there is no abnormality from the virtual manufacture of the product, the physical manufacturing apparatus physically manufactures the product.
