Digital Signature Verification for Secure Network Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for secure data transmission in networks rely on encryption, which requires decryption for processing, making data vulnerable to manipulation and trust issues if the encryption path is compromised, and cannot establish trust between all network components without complete verification.
Innovation Solution
A method involving cryptographic key pairs with public and private keys for digital signing, where digital signatures are included in subsequent data packets to ensure authenticity and integrity, allowing verification and checking of data packets across network components, ensuring secure transmission and bidirectional exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is used for secure data transmission, then data confidentiality is improved, but data must be decrypted for processing making it vulnerable to manipulation
Solution Approach 1:
The patent segments the protection mechanism into two independent parts: digital signatures for authenticity/integrity and optional encryption for confidentiality. This allows data to be signed without being decrypted, separating the verification function from the decryption function, thereby maintaining security without requiring full decryption for processing.
Solution Approach 2:
The patent introduces digital signatures as an intermediary mechanism that provides authentication and integrity verification without requiring decryption. The signature acts as a mediator that proves data authenticity while allowing the data to remain encrypted or unencrypted without compromising security.
2Reliability
If complete verification of the entire transmission path is performed, then trustworthiness is improved, but complexity and time consumption increase
Solution Approach 1:
The patent extracts the authentication function from the complete path verification requirement. By using digital signatures, the receiver can verify data authenticity without needing to verify or trust intermediate nodes, removing the complexity of complete path verification while maintaining trustworthiness.
Solution Approach 2:
The patent applies preliminary action by signing data at the source before transmission. The digital signature is created in advance by the sender, allowing receivers to verify authenticity without performing complex verification of the entire transmission path, thus simplifying the verification process while maintaining reliability.
3Reliability
If digital signatures are included in subsequent transmissions, then authenticity and integrity are improved, but data packet size increases
Solution Approach 1:
The patent uses parameter changes by employing efficient digital signature algorithms that minimize the size overhead. The signature length can be adjusted based on security requirements, allowing optimization between security strength and data packet size, thus improving authenticity while controlling the increase in quantity.
