Access Network Selective Security Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, security processing of data can degrade the performance of data transmission, as not all data requires security measures, leading to unnecessary processing and performance reduction.
Innovation Solution
An access network device determines whether to perform security processing on data based on auxiliary information from a core network device or terminal device, allowing for selective security processing to improve transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security processing is performed on all data, then data security is improved, but data transmission performance deteriorates
Solution Approach 1:
The patent applies selective security processing where different data packets receive different security treatments based on their specific requirements. The network device determines whether each data packet needs security processing based on auxiliary information, applying security measures only where necessary rather than uniformly to all data, thus resolving the contradiction between security and transmission performance.
2Reliability
If security processing is performed on unnecessary data, then security coverage is improved, but resource utilization deteriorates
Solution Approach 1:
The patent extracts and identifies the essential characteristic of data packets that determines whether security processing is needed. By using auxiliary information to determine security requirements, the system removes unnecessary security processing from data packets that do not require it, reducing wasted computational resources while maintaining security coverage for packets that actually need protection.
