Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted through a radio network to a remote central server, then data can be stored for research and development purposes, but security and certification problems arise during transmission and storage
Solution Approach 1:
The patent implements preliminary certification actions before data transmission begins. The transmitting device and receiving device perform mutual authentication and exchange certification information in advance, establishing secure credentials before the actual data transfer occurs. This preliminary certification process ensures that both devices are verified and authorized, preventing security breaches during subsequent data transmission and storage operations.
2Object-affected harmful factors
If mutual authentication is implemented between transmitting and receiving devices, then security against external malicious attacks is improved, but the complexity of the certification process increases
Solution Approach 1:
The patent introduces certification information as an intermediary element that mediates the authentication process between transmitting and receiving devices. Instead of complex direct verification protocols, the devices exchange certification information containing authentication credentials, which serve as a trusted intermediary. This intermediary mechanism simplifies the overall process by providing a standardized format for mutual authentication, reducing complexity while maintaining strong security against malicious attacks.

AI summary
Discussed are a cross certification method and a certifying device to perform the method. The certifying device can include a certification communication unit; a certification storage unit; and a certification control unit, wherein when a first certification is approved, the certification control unit encrypts a second identification information with a unidirectional encryption algorithm to generate a certification cryptogram, and transmits the certification cryptogram to an electronic device to request a second certification, when receiving a first random number in response to the request for the second certification, the certification control unit inputs the second identification information and an initial vector to a random number generating algorithm to generate a second random number, and the certification control unit compares the first random number and the second random number to verify the first random number, and determines whether to approve the second certification according to a result of the verification.
