Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure content distribution systems face challenges in providing automated and differentiated access and billing control, especially for mobile devices and smart objects, which are vulnerable to attacks and require secure key management across multiple domains, while also ensuring user data privacy and control.
Innovation Solution
A closed cryptosystem using a double-tier encrypting cryptographic key structure for secure content distribution, allowing end-users to safely share personal data while ensuring data consumers cannot misuse it, with a non-storage-based processing unit that uses user-specific keys for encryption and decryption, enabling secure and traceable data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed cryptosystem with double-tier encrypting cryptographic key structure is implemented, then data security and user privacy control are improved, but device complexity increases
Solution Approach 1:
The cryptographic key structure is segmented into two distinct tiers: a first cryptographic key for encrypting service response data and a second cryptographic key for encrypting the first key. This segmentation allows each key to have a specific function, improving security while making the complex encryption process more manageable and traceable through clear separation of encryption layers.
Solution Approach 2:
The patent introduces a non-storage-based processing unit as an intermediary component that generates and manages the cryptographic keys without storing sensitive data. This intermediary handles the complex key management operations, reducing the burden on end-user devices while maintaining high security standards through centralized, secure key processing.
2Productivity
If automated and differentiated access and billing control is implemented, then service management efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements automated access control and billing management where the non-storage-based processing unit automatically generates cryptographic keys, encrypts data, and manages access permissions without requiring manual intervention. The system autonomously handles service provisioning, key distribution, and billing control, significantly improving management efficiency while the automation masks the underlying complexity from end users.
3Adaptability or versatility
If end-users can monetize their data with transparent consent, then user control and data value realization are improved, but authorization management complexity increases
Solution Approach 1:
The system performs preliminary authorization setup by establishing a secure cryptographic framework before data sharing occurs. The non-storage-based processing unit pre-generates cryptographic keys and sets up access control policies, allowing end-users to grant or revoke data access permissions in advance. This preliminary setup enables flexible user control over data monetization while the pre-configured security infrastructure manages the authorization complexity.

AI summary
Aspects of the disclosure provides a secure key management and data transmission system that includes a transmission system, a data consumer network device, a user network device, and a data transmission network. The transmission management system is configured to receive user-specific data from the user network device via the data transmission network and receive a request for a service corresponding to processing the user-specific data according to a proprietary process provided by the data consumer network device. The transmission management system is also configured to generate service response data based on processing the user-specific data according to the proprietary process in response to the received request, encrypt the service response data to become single-encrypted service response data, transmit the single-encrypted service response data to the data consumer network device, and receive and store double-encrypted service response data from the user network device.
