Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic functions are implemented in software on the main processor, then data security is improved, but processing performance deteriorates and power consumption increases
Solution Approach 1:
The cryptographic processing functionality is segmented from the main processor and implemented as a separate hardware accelerator component within the RFID integrated circuit. This segmentation allows the main processor to handle general-purpose tasks while the dedicated accelerator handles cryptographic operations, resolving the contradiction by improving both security (through hardware-level cryptographic implementation) and performance (through parallel specialized processing).
Solution Approach 2:
The patent replaces software-based cryptographic processing (mechanical/system-level operation) with hardware-based cryptographic acceleration (physical circuit operation). This substitution eliminates the performance overhead and power consumption issues associated with software implementation while maintaining or enhancing data security through hardware-enforced cryptographic operations.
2Reliability
If cryptographic functions are executed by the main processor, then data security is improved, but power consumption increases
Solution Approach 1:
By segmenting cryptographic operations into a separate hardware accelerator, the main processor's power consumption is reduced as it no longer needs to execute cryptographic software routines. The dedicated accelerator operates with lower power requirements for cryptographic tasks, resolving the contradiction between maintaining data security and reducing overall power consumption.
Solution Approach 2:
The replacement of software-based cryptographic execution with hardware-based acceleration fundamentally changes the energy consumption profile. Hardware circuits perform cryptographic operations more efficiently with lower power consumption compared to software interpretation, while maintaining the same security level through hardware-enforced cryptographic protocols.
3Reliability
If a cryptographic module is integrated into the RFID device, then data security is improved, but device complexity increases
Solution Approach 1:
The cryptographic accelerator is merged with the RFID integrated circuit, combining security functionality with the existing device architecture. This integration approach adds cryptographic capabilities without requiring separate external security modules, thereby improving data security while minimizing the increase in device complexity through unified design.
Solution Approach 2:
The RFID integrated circuit is designed with multi-functionality, serving both as an identification device and as a secure cryptographic processing unit. By making the device universal in its capabilities, the patent improves data security through integrated cryptographic functions while avoiding the complexity of separate dedicated security hardware.
