Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asymmetric key encryption is used, then security is improved, but computational cost and resource consumption increase significantly
Solution Approach 1:
The patent segments the encryption process into two distinct phases: an asymmetric key exchange phase for establishing security, and a symmetric encryption phase for actual data transmission. This segmentation allows the system to use computationally expensive asymmetric operations only when necessary (key establishment) and cheaper symmetric operations for the bulk of communication, resolving the contradiction between security and computational cost.
Solution Approach 2:
The patent introduces a symmetric key as an intermediary that bridges asymmetric key exchange and data encryption. The asymmetric protocol establishes this symmetric key through matrix operations, which then serves as the foundation for efficient symmetric encryption. This intermediary allows the system to leverage the security benefits of asymmetric encryption while avoiding its high computational cost for actual data transmission.
2Reliability
If asymmetric key encryption is used, then key privacy is maintained, but communication efficiency decreases
Solution Approach 1:
The patent divides communication into key establishment (asymmetric) and data transmission (symmetric) segments. The asymmetric protocol ensures key privacy during establishment, while the symmetric protocol ensures communication efficiency during data transmission, resolving the contradiction between key privacy and communication efficiency.
Solution Approach 2:
The patent changes the encryption parameter from asymmetric keys to symmetric keys after the initial exchange. By transitioning from asymmetric to symmetric encryption parameters, the system maintains the security benefits of asymmetric key privacy while achieving the efficiency of symmetric communication.
3Use of energy by moving object
If symmetric key encryption is used, then computational cost is reduced, but key distribution security becomes vulnerable
Solution Approach 1:
The patent uses asymmetric key exchange as an intermediary mechanism to securely distribute symmetric keys. The asymmetric protocol acts as a trusted channel that enables secure key distribution without requiring prior shared secrets, thereby maintaining key distribution security while allowing the use of computationally efficient symmetric encryption.
Solution Approach 2:
The patent performs preliminary asymmetric key exchange and symmetric key derivation before actual data transmission begins. This preliminary action establishes secure communication parameters in advance, allowing subsequent data transmission to use efficient symmetric encryption without compromising key distribution security.
4Ease of operation
If asymmetric encryption is used without prior secrets, then key establishment is simplified, but computational resources required increase
Solution Approach 1:
The patent segments key establishment operations into asymmetric matrix-based key exchange and subsequent symmetric encryption. This segmentation allows the system to use computationally intensive asymmetric operations only for initial key establishment and switch to resource-efficient symmetric operations for ongoing communication, resolving the contradiction between ease of key establishment and information resource consumption.
Data Source
AI summary
A system and method for generating data for use in cryptography or secure modulation is provided. The method may include randomly generating a public code using a secret key, wherein the public code includes an interior matrix and a summing matrix, both having a predetermined dimension of rows and columns. After receipt of the public code and the rule of obfuscation by a receiving computer node, the method may further include generating an obfuscated matrix pattern from the interior matrix, based upon the rule of obfuscation. For symmetric key utilization, the receiving computing node can generate a symmetric code from the summing matrix, based upon the rule of obfuscation, which can be for use in communication between computing nodes. Alternatively, a server node can retrieve or generate the public code and the rule of obfuscation to the computing node. Thereby, each node is enabled to communicate privately with each other.
