Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional secure access methods (unique codes sent to mobile phones) are used for Internet banking, then security is improved, but user comfort and simplicity deteriorate due to required client interaction
Solution Approach 1:
The auxiliary security device automatically performs authentication functions without requiring user interaction. The device autonomously generates cryptographic keys, establishes wireless connections, and verifies authenticity through technical means rather than manual code entry or button pressing, allowing the system to secure itself without client involvement.
Solution Approach 2:
An auxiliary security device is introduced as an intermediary between the portable electronic device and the banking system. This mediator handles the complex security operations including key generation, wireless communication establishment, and authentication verification, freeing the user from direct interaction with security mechanisms while maintaining high security standards.
2Reliability
If stand-alone security devices requiring user interaction are used, then security is improved, but ease of operation deteriorates due to required user actions
Solution Approach 1:
The auxiliary security device is designed to autonomously perform all security operations including generating cryptographic key pairs, establishing Bluetooth connections, and verifying device authenticity through technical protocols rather than requiring users to press buttons, enter PINs, or manually input codes.
Solution Approach 2:
Manual mechanical interactions (button pressing, code typing, physical card insertion) are replaced with automated electronic and cryptographic processes. The system uses wireless communication protocols and cryptographic key exchange algorithms to achieve authentication without physical user intervention beyond initial device setup.
3Ease of operation
If automatic authentication without user interaction is implemented, then user comfort is improved, but security may deteriorate due to reduced verification steps
Solution Approach 1:
The auxiliary security device serves as a trusted intermediary that implements robust cryptographic verification protocols automatically. It generates and manages secure key pairs, establishes encrypted wireless connections, and performs mutual authentication with the banking system, providing automated convenience without compromising security through the use of cryptographically secure verification mechanisms.
Solution Approach 2:
Manual verification steps are replaced with automated cryptographic verification processes. The system uses public-key cryptography, digital signatures, and secure key exchange protocols to perform authentication automatically, maintaining high security standards while eliminating the need for user interaction with verification mechanisms.
4Reliability
If multiple security verification steps are implemented, then security is improved, but device complexity increases
Solution Approach 1:
Multiple security functions (key generation, wireless communication, authentication verification, session management) are merged into a single auxiliary security device. This consolidation integrates complex cryptographic operations and communication protocols into one unified hardware module, reducing the overall system complexity while maintaining comprehensive security functionality.
Solution Approach 2:
The auxiliary security device is designed as a multi-functional universal security solution that handles key generation, wireless connection establishment, authentication, and encrypted communication all in one device. This universal design eliminates the need for multiple separate security components, reducing device complexity while providing comprehensive security coverage.
