Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed password is used for login, then the operation is simple and easy to remember, but the security is compromised due to potential unauthorized access and brute-force attacks
Solution Approach 1:
The patent implements dynamic password generation where the login code changes over time or with each use. The control apparatus generates a new login code based on previous codes and algorithmic operations, ensuring that each login attempt requires a fresh credential rather than a static password. This dynamic approach maintains ease of operation while significantly improving security against unauthorized access and brute-force attacks.
Solution Approach 2:
The system changes the parameter of the login code from fixed to variable. By implementing time-based or usage-based code generation with algorithmic transformation, the login credential becomes a changing parameter rather than a constant. This allows the system to maintain user-friendly login processes while preventing security vulnerabilities associated with fixed passwords.
2Device complexity
If a fixed password is used, then the system structure is simple, but the system is prone to being forgotten or brute-force broken
Solution Approach 1:
The system performs preliminary actions by pre-establishing an algorithmic framework for code generation. The control apparatus stores previous login codes and uses them as basis for generating new codes through predefined algorithms. This preliminary setup enables automatic dynamic code generation without requiring complex external authentication systems, maintaining relatively simple device structure while improving password security through automated cryptographic operations.
Solution Approach 2:
The system provides self-service functionality by automatically generating login codes using its own stored historical codes and algorithmic processes. The control apparatus independently creates new authentication credentials without requiring manual password distribution or external authentication servers. This self-service mechanism reduces system complexity while enhancing security through automated, unpredictable code generation.
3Reliability
If dynamic password generation is implemented, then the security is improved, but the system complexity increases
Solution Approach 1:
The patent segments the authentication system into distinct functional modules: a code generation module that creates login codes based on previous codes, a code storage module that maintains historical codes, and a verification module that validates incoming authentication attempts. This segmentation allows the complex dynamic authentication process to be managed through discrete, manageable components, reducing overall system complexity while maintaining enhanced security through structured code generation and verification.
