Laboratory Equipment Security Gateway for Encrypted Data Obfuscation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data-generating equipment in insecure environments faces challenges with unauthorized access and data manipulation due to compromised firewalls, which can lead to data breaches and equipment vulnerability.
Innovation Solution
A network security device with a security module and firewall acts as an intermediary, regulating traffic, applying encryption, and generating decoy data to protect sensitive information, using multiple encryption keys for differential access and obfuscation techniques to secure data transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is made accessible to personnel in insecure environments, then data utility and operational monitoring are improved, but data security and confidentiality deteriorate
Solution Approach 1:
A security device is positioned between the data-generating equipment and the network to act as an intermediary. This device receives data from the equipment, applies encryption and obfuscation transformations, and then transmits the protected data to storage devices on the network. The intermediary prevents direct access to raw data while still enabling authorized personnel to access protected data through proper decryption channels.
Solution Approach 2:
Encryption and obfuscation are applied to data before it leaves the data-generating equipment and enters the network. This preliminary security transformation ensures that data is protected during transmission and storage, and that any unauthorized access attempts on the network will only encounter encrypted/obfuscated data rather than plaintext sensitive information.
2Reliability
If encryption is applied to protect data, then data confidentiality is improved, but data access complexity deteriorates
Solution Approach 1:
The security device segments the data processing function by separating encryption/obfuscation operations from data transmission and storage. The device applies different security transformations to different data streams, managing multiple encryption keys separately, and handling decoy data generation independently. This segmentation allows complex security operations to be managed in discrete, controllable units.
Solution Approach 2:
The security device automatically manages encryption key generation, rotation, and distribution without requiring manual intervention. It self-manages the obfuscation and de-obfuscation processes, and automatically handles the generation and management of decoy data. This automation reduces the operational complexity burden on users while maintaining strong security.

AI summary
Data protection systems and methods. One system includes comprising a network security device including a security module and a firewall. The network security device is configured as an intermediary device between laboratory equipment and a communication network. The network security device includes a memory storing one or more applications, an input/output interface configured to receive data generated by the laboratory equipment, and an electronic processor. The electronic processor configured to, through execution of the one or more applications, modify the data received from the laboratory equipment to protect sensitive data included in the data, encrypt the data, as modified, to generate a data file, transfer the data file to one or more devices over the network, and prevent network traffic from reaching the laboratory equipment.
