Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing 2G, 3G, and 4G mobile phones use standard encryption protocols, then device compatibility and ease of operation are maintained, but security against quantum computer attacks is insufficient
Solution Approach 1:
The patent introduces a SIM card as an intermediary security device that implements quantum-resistant encryption algorithms (e.g., AES-256, eAES) independently of the mobile phone's native processor. This mediator approach allows legacy devices to achieve quantum-resistant security without requiring complex modifications to the phone's core architecture, resolving the contradiction between enhanced security and device complexity.
Solution Approach 2:
The patent changes the encryption parameter from standard AES-128 to AES-256 or eAES algorithms with 256-bit keys. This parameter change increases security against quantum attacks while maintaining compatibility with existing hardware through the SIM card's hardware accelerator, avoiding the need for complete device replacement or complex software modifications.
2Reliability
If quantum-resistant encryption with 256-bit standards is implemented, then security against quantum attacks is improved, but hardware requirements and device complexity increase
Solution Approach 1:
The SIM card serves as a dedicated intermediary hardware module that offloads quantum-resistant encryption operations from the main processor. It includes specialized hardware accelerators for AES-256 and eAES algorithms, concentrating the complexity in a single replaceable component rather than requiring complex modifications across the entire device architecture.
Solution Approach 2:
The patent extracts the quantum-resistant encryption functionality from the main mobile phone system and places it in a separate, dedicated SIM card module. This extraction allows the core device to remain simple while the SIM card handles all complex quantum-resistant encryption operations independently through its own hardware accelerators.
3Adaptability or versatility
If legacy communication devices are upgraded to support New Radio networks, then network compatibility and adaptability are improved, but device complexity and upgrade costs increase
Solution Approach 1:
The SIM card acts as an intermediary that provides the upgraded protocol stack for New Radio (5G) networks. Legacy mobile phones can connect to 5G networks through the SIM card, which handles the complex protocol translations and security operations, while the phone itself maintains its original simpler architecture.
Solution Approach 2:
The SIM card is designed with multi-functionality to support multiple network generations (2G, 3G, 4G, and 5G New Radio) through a single device. It dynamically loads appropriate protocol stacks based on network requirements, providing universal network compatibility without requiring separate hardware upgrades for each network generation.
