Network Security Content Checker Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems face risks of data damage and information leaks due to component failures that can cause data to bypass content checkers, leading to potential attacks or unauthorized data transmission.
Innovation Solution
Implementing an encryption method between the network interface card and the content checker using a key agreement protocol, such as Diffie-Hellman, and employing symmetric or asymmetric encryption to ensure that mis-delivered data is rendered unintelligible, thereby preventing damage or leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted in a format that is invalid with respect to other software or peripheral firmware, then the risk of damage from misdelivered data is reduced, but the complexity of the system increases due to format validation requirements
Solution Approach 1:
The patent applies parameter changes by transforming data into a specific invalid format (changing the parameters of data representation) that is deliberately incompatible with standard software interpretations. This format transformation ensures that misdelivered data cannot be executed or processed harmfully by other system components, while the content checker can still validate and process the transformed data correctly.
2Reliability
If encryption is applied to data transmitted between network interface card and content checker, then protection against misdelivered data is improved, but processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by performing encryption on data before transmission between the network interface card and content checker. This advance encryption ensures that even if data is misdelivered or intercepted, it remains protected and unintelligible to unauthorized components. The encryption is performed proactively as part of the data transmission protocol rather than reactively after potential threats are detected.
