Selective Encryption for Call Distribution Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face inefficiencies due to duplicative processing across different network elements, leading to network inefficiencies, especially with the increasing bandwidth demands of user-plane traffic, where most traffic is already encrypted end-to-end, rendering additional encryption between points unnecessary.
Innovation Solution
Implementing systems and methods for selectively applying encryption based on the direction, prior encryption status, and complexity of network traffic, focusing on downstream and upstream traffic, and using hardware accelerators to determine the need for encryption, thereby reducing unnecessary processing and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is applied at every network element, then security is improved, but network efficiency deteriorates due to duplicative processing
Solution Approach 1:
The patent changes the parameter of encryption application from universal (all traffic) to selective (only when needed). By detecting whether traffic is already encrypted and adjusting encryption application accordingly, the system maintains security while eliminating duplicative processing. This parameter change enables the system to adapt encryption behavior based on traffic conditions, resolving the contradiction between security and efficiency.
Solution Approach 2:
The patent implements self-service by having network elements automatically detect the encryption status of incoming traffic and make independent decisions about whether to apply encryption. This eliminates the need for manual configuration and allows each network element to optimize its own processing based on real-time traffic characteristics, thereby improving efficiency while maintaining security.
2Reliability
If encryption is applied to all network traffic, then security is improved, but processing load increases unnecessarily
Solution Approach 1:
The patent applies local quality by treating different types of traffic differently based on their specific characteristics. Instead of applying uniform encryption to all traffic, the system examines individual traffic flows to determine their encryption status and applies encryption only where necessary. This localized approach reduces processing load on unnecessary encryption operations while maintaining security where required.
Solution Approach 2:
The patent implements partial action by applying encryption only to the extent necessary - specifically, only to unencrypted traffic that requires protection. By detecting the encryption status and applying encryption selectively rather than universally, the system avoids excessive processing load on already-encrypted traffic while maintaining adequate security coverage for traffic that needs protection.
3Reliability
If network elements apply processing to all traffic, then security coverage is improved, but network bandwidth efficiency deteriorates
Solution Approach 1:
The patent extracts the encryption function from universal application and isolates it to only where needed. By detecting traffic characteristics and extracting encryption processing from the general processing pipeline for already-encrypted traffic, the system maintains security coverage for critical traffic while eliminating unnecessary processing overhead that would consume network bandwidth resources.
