Secure Data Encryptor for Portable Storage Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods from portable storage mediums lack comprehensive security measures, particularly in ensuring encrypted data integrity and user authentication, leading to vulnerabilities in data protection during transfer between local and cloud storage systems.
Innovation Solution
A secure data encryptor (SDE) is employed to read from and write to portable storage mediums, performing encryption, decryption, authentication, and virus scanning, using both password and storage keys, and facilitating secure data transfer between local and cloud storage systems through Ethernet or TLS connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive security measures (encryption, authentication, virus scanning) are implemented during data transfer from portable storage mediums, then data protection is improved, but device complexity increases
Solution Approach 1:
A secure data encryptor (SDE) is introduced as an intermediary device between the portable storage medium and the host system. The SDE performs all security functions (encryption, decryption, authentication, virus scanning) internally, acting as a mediator that protects data without requiring the host system to implement complex security measures. This resolves the contradiction by centralizing security complexity in a dedicated intermediary device while keeping the host system simple.
Solution Approach 2:
The security system is segmented into a dedicated secure data encryptor device that handles all security operations separately from the main host system. By dividing the system into distinct functional modules (SDE for security, host system for data processing), the complexity is isolated to a specialized component while maintaining overall system reliability.
2Productivity
If automatic encryption and decryption operations are performed by the SDE, then productivity is improved, but device complexity increases
Solution Approach 1:
The secure data encryptor is designed to perform encryption and decryption operations automatically without requiring manual user intervention. The device self-manages security operations including automatic key management, encryption/decryption processing, and virus scanning, thereby improving productivity while containing complexity within the self-service mechanism.
Solution Approach 2:
Multiple security functions (encryption, decryption, authentication, virus scanning) are merged into a single integrated secure data encryptor device. This consolidation improves productivity by handling all security operations through one unified system rather than requiring separate devices for each function, while the integrated design manages complexity through functional integration.

AI summary
Apparatus and methods related to securely transmitting data between a portable storage or other medium and a data storage system. In one approach, a portable storage medium drive reads data from a portable storage medium, and a password key decryption unit automatically decrypts the data using a password key in response to having obtained the password key. A storage key encryption unit automatically encrypts the first password key decrypted data using a storage key in response to an availability of the password key decrypted data. A storage interface automatically transmits the storage key encrypted data to the data storage system in response to an availability of the storage key encrypted data.
