Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive security services are provided to all network packets, then security coverage is improved, but system resource consumption increases and operational efficiency decreases
Solution Approach 1:
The patent segments network packets into different categories based on user authentication results and packet characteristics. By dividing the security processing into different queues (high-priority and low-priority) and applying different security service levels to different segments, the system achieves both comprehensive security coverage and improved operational efficiency through differentiated processing
2Reliability
If all packets undergo identical security checks, then security consistency is improved, but resource waste increases due to redundant checks
Solution Approach 1:
The patent implements local quality by providing different security service levels to different packets based on their characteristics and user authentication results. High-priority packets receive comprehensive security checks while low-priority packets receive streamlined processing, eliminating redundant checks for packets that don't require full security validation
3Reliability
If security gateway processes all packets with full authentication, then security level is improved, but processing speed decreases
Solution Approach 1:
The patent performs preliminary user authentication and packet classification before full security processing. By pre-categorizing packets into priority queues based on initial authentication results and packet characteristics, the system prepares the processing structure in advance, enabling faster subsequent processing while maintaining security levels
4Productivity
If differentiated security services are implemented, then operational efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic packet classification and priority queue assignment based on real-time user authentication results and packet characteristics. The system dynamically adjusts security service levels and processing priorities rather than using static rules, improving operational efficiency while managing complexity through adaptive rather than rigid differentiation

AI summary
Disclosed is a user authentication-based packet classification method and apparatus for providing differentiated security services in a ship network. A user authentication-based packet classification method includes receiving an authorization code request message from a user terminal including a client, authenticating and authorizing a user of the client based on the authorization code request message, transmitting an authorization code response message to the user terminal in response to the authorization code request message, receiving an access token request message from the user terminal based on the authorization code response message, and transmitting an access token response message including an access token to the user terminal in response to the access token request message.
