Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NOR flash memory is used for storing system software and data, then storage capability is provided, but data security is compromised due to ease of decoding and analysis
Solution Approach 1:
The patent applies preliminary action by performing encryption on data before it is stored in the NOR flash memory. The encryption element encrypts the data to be written, and the decryption element decrypts the data when read, ensuring that data is protected from cracking before any analysis can occur. This preemptive security measure prevents the harmful factor of data cracking while maintaining storage capability.
2Reliability
If encryption processing is performed on data, then data security is improved, but device complexity increases due to additional encryption and decryption elements
Solution Approach 1:
The patent implements self-service by integrating the encryption and decryption functions directly into the storage system components. The encryption element and decryption element are incorporated within the storage device architecture, allowing the system to encrypt and decrypt data automatically during read/write operations without requiring external security hardware or complex manual intervention. This reduces overall system complexity while maintaining strong data security.
