Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical interface devices are used for data transmission, then connection stability is improved, but ease of operation deteriorates due to manual connection requirements
Solution Approach 1:
The patent replaces the mechanical physical connection system with a wireless communication system. The wireless port connection device establishes data transmission channels through wireless signals instead of physical cables, eliminating the need for manual plugging and unplugging while maintaining connection stability through authentication and encryption mechanisms
2Reliability
If physical ports are used for communication, then security is improved through physical control, but adaptability deteriorates due to limited connectivity options
Solution Approach 1:
The wireless port connection device serves multiple functions: it provides wireless communication capability, implements authentication security, performs data encryption, and enables remote connectivity. This multi-functional design allows the device to maintain security while significantly improving adaptability to various connectivity scenarios
3Ease of operation
If wireless communication is implemented without authentication, then ease of operation is improved, but security deteriorates due to unauthorized access vulnerabilities
Solution Approach 1:
The patent implements preliminary authentication action before data transmission begins. The wireless port connection device performs mutual authentication with remote devices through certificate verification and key exchange processes, ensuring security is established in advance while maintaining ease of wireless operation
4Productivity
If data is transmitted without encryption, then productivity is improved through faster transmission, but loss of information deteriorates due to data security risks
Solution Approach 1:
The patent changes the parameter of data state from plaintext to encrypted form during transmission. The wireless port connection device applies encryption algorithms to transform data into secure ciphertext, maintaining transmission efficiency while preventing information loss through security breaches

AI summary
Embodiments of the present disclosure relate to a method for wireless communication, a wireless port connection device, and a computer program product. The method in one embodiment is illustratively performed by a first wireless port device. The method includes: sending a first public key of the first wireless port device to an authentication server; receiving a signed first certificate from the authentication server, the first certificate comprising a server public key of the authentication server; receiving a signed second certificate from a second wireless port connection device; acquiring a second public key of the second wireless port connection device in the second certificate using the server public key; generating a symmetric key using the second public key; encrypting data using the symmetric key; and sending the encrypted data to the second wireless port connection device.
