Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional time verification manner is used to verify data transmission, then data accuracy is improved, but time synchronization errors occur and system efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a trusted relationship between client and server through public key infrastructure (PKI) before actual data transmission. The client obtains the server's public key in advance and stores it locally, eliminating the need for time synchronization and real-time key exchange during data transmission. This preliminary setup resolves the contradiction by enabling accurate verification without the time synchronization errors and efficiency losses of traditional methods.
2Reliability
If encryption key exchange manner is used to verify data transmission, then data security is improved, but handshaking time increases and system loading increases
Solution Approach 1:
The patent extracts the key exchange process from the real-time data transmission flow. Instead of performing encryption key exchange during each communication session, the system separates key establishment into a preliminary phase where the client obtains and stores the server's public key beforehand. This extraction eliminates the time-consuming handshaking process during actual data transmission while maintaining strong security through cryptographic verification using the pre-established keys.
3Reliability
If traditional verification methods are used, then data transmission security is maintained, but duplicate package transmission occurs and accuracy decreases
Solution Approach 1:
The patent implements feedback through a verification mechanism where the server signs data packets with its private key, and the client verifies each received packet using the pre-stored public key. This feedback loop ensures that every transmitted packet is authentically verified, preventing duplicate or malicious packets from being processed. The verification result feeds back into the transmission process, allowing the client to accept only genuinely authorized packets, thereby eliminating duplicate transmission issues while maintaining security.

AI summary
A data transmitting method suitable to a client and a server is provided. The method includes the following steps. The client generates an initial value. The server generates a first time in response to the initial value. The client generates a second time and a first verification hash code related with the first time and the second time. The server generates a random variable and a second verification hash code related with the first time, the random variable and the first verification hash code. The client generates a first transmitting data and a third verification hash code related with the first transmitting data, the first verification hash code and the second verification hash code. The server generates a first response message and a fourth verification hash code related with the first response message, the second verification hash code and the third verification hash code.
