Dynamic IP Verification for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods are vulnerable to interception and decryption by nefarious observers, even when using encryption, due to weaknesses in network security and the longevity of public/private keys, which can lead to undetectable 'man in the middle' attacks.
Innovation Solution
A system and method for secure data transmission that includes a request module to verify the authenticity of requests by matching public IP addresses, an encryption module to encrypt data using a dynamically selected encryption scheme, and a transfer module to transmit encrypted data, along with a setup module that provides cryptographic elements like lists of encryption schemes and keys, which can be updated periodically to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encryption with static public/private keys is used, then data confidentiality is maintained, but vulnerability to man-in-the-middle attacks increases due to key longevity and certificate validation weaknesses
Solution Approach 1:
The patent applies dynamics by transitioning from static encryption keys to dynamic key generation. Encryption keys are now generated session-by-session rather than reused long-term, and IP addresses are dynamically verified against multiple sources (DNS, reverse DNS, BGP tables) to detect spoofing attempts. This dynamic approach ensures that even if one session's keys are compromised, past and future sessions remain secure.
Solution Approach 2:
The patent implements preliminary action by performing IP address verification and authentication checks before establishing encrypted communication. The system pre-validates the sender's IP address against multiple authoritative sources and establishes cryptographic bindings before data transmission begins, preventing man-in-the-middle attacks from taking effect.
2Reliability
If IP address verification is performed to detect spoofing, then authenticity is improved, but network performance deteriorates due to additional validation steps
Solution Approach 1:
The patent applies partial action by selectively performing verification steps based on risk assessment. Not all connections undergo the full multi-source IP verification process; instead, the system performs baseline verification and only activates additional validation steps when anomalies are detected or for high-risk transactions, balancing security with performance.
3Object-affected harmful factors
If encryption schemes are changed frequently to enhance security, then resistance to decryption improves, but system complexity increases due to key management
Solution Approach 1:
The patent implements self-service through automated key management systems that handle generation, distribution, rotation, and revocation of encryption keys without manual intervention. The system automatically binds keys to verified IP addresses and session identifiers, and seamlessly rotates keys between sessions, eliminating the complexity burden from users while maintaining strong security.
Data Source
AI summary
An apparatus, system, and method are disclosed for secure data transmissions. A method includes receiving a request for data that is encrypted according to a first encryption scheme, and determining a first public IP address associated with the request. The first public IP address identifies a remote client that created the request and is located in a field of a data packet that includes the request. The method includes determining a second public IP address associated with the request that identifies a sender of the request and is determined dynamically when the request is received. The method includes verifying an authenticity of the request in response to the first public IP address of the remote client matching the second public IP address of the sender. The method includes encrypting the requested data according to a second encryption scheme, and transferring the data to the remote client.
