Engineering Contradiction Analysis
1Productivity
If application information is carried in service packets for network resource allocation, then network resource allocation efficiency is improved, but reliability deteriorates due to improper use and embezzlement of application information
Solution Approach 1:
The patent applies preliminary action by generating verification information (such as HMAC values or digital signatures) in advance during packet encapsulation. The verification information is calculated based on the application information and packet header before the packet is transmitted through the network, enabling receiving devices to verify integrity without adding real-time processing overhead that would affect resource allocation efficiency.
Solution Approach 2:
The patent introduces verification information as an intermediary element between the application information and the packet processing system. This verification information (HMAC or digital signature) acts as a mediator that enables trust and integrity verification without requiring the receiving devices to trust the application information directly, thus resolving the reliability issue while maintaining allocation efficiency.
2Reliability
If verification information is added to packets for integrity checking, then reliability is improved, but device complexity increases due to additional verification processing
Solution Approach 1:
The patent replaces complex manual verification processes with automated cryptographic mechanisms. Instead of requiring complex logic to verify application information integrity, the system uses HMAC or digital signature algorithms that automatically provide verification through mathematical operations, reducing device complexity while improving reliability.
Solution Approach 2:
The patent changes the verification approach from complex multi-step validation to simple parameter comparison. The verification information is generated once during encapsulation and then simply compared against newly calculated values at receiving devices, transforming a complex verification process into a straightforward parameter matching operation.
