Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If memory devices are used to store data without additional validation mechanisms, then storage capacity and simplicity are maintained, but data authenticity and integrity cannot be validated against hacking or faults
Solution Approach 1:
The patent combines the memory device with blockchain technology by integrating cryptographic hash functions and digital signature verification directly into the memory system. The memory device generates cryptographic hashes of stored data and links them to a blockchain structure, merging storage functionality with security validation in a unified system that prevents data tampering while maintaining operational simplicity.
Solution Approach 2:
The patent introduces cryptographic hash values as an intermediary element between the stored data and the validation mechanism. These hash values serve as mediators that represent the data's integrity state without requiring direct inspection of the underlying stored information, enabling efficient verification while preserving data confidentiality and reducing the complexity of direct data validation.
2Reliability
If cryptographic validation is implemented in memory devices, then data security is improved, but additional components or circuitry would be required
Solution Approach 1:
The patent makes the memory device multi-functional by enabling it to perform both traditional data storage operations and cryptographic validation operations using the same physical infrastructure. The memory controller leverages existing processing capabilities to execute cryptographic hash functions and manage blockchain interactions, allowing a single device to serve multiple purposes without requiring separate dedicated security hardware.
Solution Approach 2:
The memory device performs self-validation by autonomously generating cryptographic hashes of its stored data and verifying these hashes against the blockchain record. This self-service capability allows the memory device to validate its own data integrity without requiring external validation hardware, reducing system complexity while maintaining robust security through built-in cryptographic verification.
