Hash-Based Secure Data Transmission Without Time-Sync Certificates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure data transmission methods over the Internet, such as SSL, are vulnerable to invalid certificates due to time differences between sender and server, leading to potential third-party interception and reliance on user acceptance or time-based certificates.
Innovation Solution
A method and system for secure data transmission involving the generation of a character string, creation of a hash key using a private key, and encryption of data, along with transmission of an identification key and encrypted data, eliminating the need for certificates and ensuring dynamic encryption keys for each data packet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-based certificates are used for secure data transmission, then authentication is provided, but validity errors occur due to time differences between sender and server
Solution Approach 1:
The patent changes the parameter from time-based certificate validity to a deterministic hash-based validity mechanism. Instead of relying on timestamps that may differ between systems, the invention uses a hash function that processes the private key and data to generate a unique hash key, eliminating time synchronization requirements while maintaining authentication reliability.
2Reliability
If certificates are rejected due to invalidity, then security is maintained, but additional validation steps are required
Solution Approach 1:
The invention implements self-service authentication where the sender automatically generates and transmits the hash key derived from their private key and the data. The recipient can independently verify the authenticity by regenerating the same hash key using the provided private key and comparing it with the transmitted hash key, eliminating the need for complex third-party certificate validation.
3Object-affected harmful factors
If SSL encryption is used, then data protection is provided, but third-party interception remains possible due to certificate acceptance issues
Solution Approach 1:
The patent extracts the vulnerable certificate validation step from the encryption process. Instead of relying on SSL certificates that require user acceptance or server validation, the invention directly embeds the authentication mechanism within the data transmission itself through hash key generation, eliminating the intermediate certificate layer that enables third-party interception.
