Air-Gapped Encrypted Storage for Secure Offline Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing data storage and transfer are inadequate, as they often have individual vulnerabilities that can lead to data destruction or compromise through hardware failure, cyberattacks, or unauthorized access.
Innovation Solution
Implementing an air-gapped computer system with ruggedized, encrypted on-site and portable storage, using secure offline transfer methods and encryption keys to ensure data integrity and isolation from networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored on networked computers with encryption and antivirus software, then data security against cyberattacks is improved, but vulnerability to hardware failure and physical damage increases
Solution Approach 1:
The system divides data storage into multiple separate locations: networked storage for accessibility, air-gapped storage for security, and physical copies for disaster recovery. This segmentation ensures that hardware failure in one location does not compromise all data copies.
Solution Approach 2:
A physical intermediary (USB drive or portable hard drive) is used to transfer data between the networked computer and air-gapped storage. This intermediary breaks the digital connection while maintaining data integrity, protecting against both cyberattacks and hardware failures.
2Reliability
If air-gapped storage is used to prevent cyberattacks, then data security against hacking is improved, but ease of data transfer and accessibility deteriorates
Solution Approach 1:
A portable storage device serves as an intermediary that bridges the air-gapped and networked environments. Data is transferred physically rather than digitally, maintaining security while enabling convenient data movement between systems.
Solution Approach 2:
The system dynamically switches between connected and air-gapped modes based on operational needs. The air-gapped computer connects to portable storage when data transfer is needed, then disconnects to maintain security, providing both accessibility and protection.
3Reliability
If multiple storage locations are used for data redundancy, then data reliability is improved, but system complexity increases
Solution Approach 1:
The storage system is segmented into three distinct layers: networked storage for daily operations, air-gapped storage for security, and physical copies for disaster recovery. Each layer has a specific function, simplifying management despite the multiple locations.
Solution Approach 2:
The portable storage device performs multiple functions: it acts as a transfer medium between air-gapped and networked systems, serves as a backup copy, and can be physically transported for disaster recovery. This multi-functionality reduces the need for separate systems.
Data Source
AI summary
A method of secure data transfer and storage using ae storage device storing encrypted information. The method uses a host that stores and transfers encrypted sensitive information and a customer that desires the information to be securely stored. The customer chooses a unique encryption code to encrypt sensitive information and uploads the information to a host. Then the host transfers the information to the storage device. Connections between the host and customer are intermittent and done so the storage device remains isolated from networks outside of the host.
