Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic services are provided through web pages, then authentication and encryption functionality is available to users, but the system becomes vulnerable to security breaches and hacking
Solution Approach 1:
The patent extracts the cryptographic key storage and processing functionality from the web page environment and places it in a dedicated cryptographic device. The web page only contains a user interface that communicates with the cryptographic device via a persistent connection, thereby removing the vulnerable element (cryptographic keys) from the exposed web environment while maintaining the service functionality.
Solution Approach 2:
The patent introduces a cryptographic device as an intermediary between the user interface (web page) and the cryptographic operations. This intermediary handles all key storage and cryptographic processing, acting as a secure buffer that protects the web page environment from direct exposure to sensitive cryptographic materials while still enabling web-based cryptographic services.
2Ease of operation
If cryptographic processing is performed directly in the browser, then user convenience is improved, but security risks increase due to exposure of cryptographic keys
Solution Approach 1:
The patent extracts the private key storage and cryptographic processing from the browser environment and relocates it to a separate cryptographic device. The browser maintains only the user interface and communication protocols, while the cryptographic device handles all sensitive operations locally, eliminating private key exposure risks while preserving user convenience through seamless integration.
Solution Approach 2:
The cryptographic device serves as an intermediary that the browser communicates with via a persistent peer-to-peer connection. This intermediary handles all cryptographic operations locally without exposing private keys to the browser environment, thereby maintaining ease of operation while eliminating security vulnerabilities associated with key exposure.
3Productivity
If a persistent peer-to-peer connection is established between browser and cryptographic device, then cryptographic service efficiency is improved, but system complexity increases
Solution Approach 1:
The patent establishes the peer-to-peer connection in advance during the initial setup phase, before cryptographic operations are needed. This preliminary action creates a persistent communication channel that remains available for subsequent cryptographic operations, eliminating the need to repeatedly establish connections and thereby improving service efficiency while managing complexity through upfront configuration.
Solution Approach 2:
The persistent peer-to-peer connection serves multiple functions: it enables authentication, encryption, decryption, and other cryptographic operations through a single unified communication channel. This multi-functional approach improves efficiency by avoiding repeated connection setup while managing complexity through a standardized, versatile connection protocol.
