Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring encrypted data in 5G networks face latency issues due to the need for decryption, analysis, and rerouting, which is problematic for applications like autonomous vehicles and medical devices that require low latency to prevent disruptions or delays in critical operations.
Innovation Solution
Implementing homomorphic encryption (HE) to allow calculations on encrypted data without decryption, and using a managing application to determine the type of data and route it efficiently within the network, along with distributed storage and blockchain for secure and low-latency data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If encrypted data is decrypted and analyzed before routing, then data processing accuracy is improved, but network latency increases
Solution Approach 1:
The system performs preliminary encryption of data before transmission, allowing the data to be processed in encrypted form without requiring decryption at intermediate nodes. This preliminary action eliminates the need for subsequent decryption operations that would cause latency, while still enabling accurate data processing through homomorphic encryption techniques.
Solution Approach 2:
Homomorphic encryption acts as an intermediary mechanism that allows data processing to occur on encrypted data itself, eliminating the need for traditional decryption-reprocess-encrypt cycles. This intermediary approach enables accurate processing while maintaining encryption throughout the transmission and processing pipeline, thus reducing latency.
2Reliability
If data is encrypted with strong encryption methods, then data security is improved, but processing speed decreases
Solution Approach 1:
The system applies strong encryption methods in advance before data transmission, using algorithms like AES-256 for initial encryption. This preliminary encryption ensures data security is established before processing begins, and the encrypted data can then be processed efficiently without requiring re-encryption or decryption operations during transmission and processing stages.
Solution Approach 2:
The system changes the encryption parameters and algorithms dynamically based on data type, sensitivity level, and processing requirements. Different encryption strengths and types are applied to different data segments, allowing optimal balance between security and processing speed for each specific data processing task.
3Adaptability or versatility
If data is routed through multiple network nodes, then data routing flexibility is improved, but network latency increases
Solution Approach 1:
The system performs preliminary routing decisions and path selection before data transmission begins, using metadata analysis to determine optimal routes in advance. This preliminary routing action eliminates the need for multiple hops and intermediate routing decisions during data transmission, reducing latency while maintaining routing flexibility through pre-computed paths.
Solution Approach 2:
The system segments data into different types and prioritizes routing decisions for different segments independently. Critical data segments receive pre-routed paths with lower latency, while less time-sensitive segments can take longer routes. This segmentation allows routing flexibility for different data types without uniformly increasing latency for all data.
Data Source
AI summary
A method of directing encrypted data transmitted wirelessly on a communication network comprising receiving encrypted data, by a managing application executing on a virtual network, from a user equipment (UE) operating on a mobile network. The managing application on the virtual network is coupled with an access node and deciphers a portion of the data encrypted with homomorphic encryption to determine a data characteristic. The managing application routes the encrypted data to a network location in response to the data characteristic of the encrypted data.
