Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cryptographic wallets rely on remembering master passwords, then authentication is simplified, but security is compromised due to potential loss or unauthorized access
Solution Approach 1:
The authentication system is segmented into multiple independent factors: something you have (physical device with NFC), something you know (passphrase), and something you are (biometric data). This segmentation eliminates the single point of failure inherent in password-only systems while maintaining ease of use through automated multi-factor verification.
Solution Approach 2:
A secure enclave or trusted execution environment acts as an intermediary between the user's biometric data and the cryptographic operations. This intermediary securely stores private keys and performs cryptographic operations without exposing sensitive data, thereby enhancing security while maintaining user-friendly authentication.
2Reliability
If multi-factor authentication is implemented, then security is enhanced, but device complexity increases
Solution Approach 1:
Multiple authentication factors are merged into a single unified authentication flow. The system combines NFC communication, biometric sensing, and cryptographic verification into one seamless process that automatically executes without requiring user coordination between separate authentication mechanisms.
Solution Approach 2:
The authentication device performs self-verification by automatically comparing biometric data against stored templates and executing cryptographic operations without external intervention. This self-service capability reduces the operational complexity for users while maintaining robust multi-factor security.
