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
An apparatus and method that includes a request module to verify public IP addresses, an encryption module to dynamically change encryption schemes and keys, and a transfer module to securely transmit data, using a dynamic selection of encryption schemes and keys to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static encryption keys and certificates are used for data transmission, then data can be encrypted and decrypted, but the system becomes vulnerable to man-in-the-middle attacks and key cracking over time
Solution Approach 1:
The patent implements dynamic encryption by allowing the encryption scheme to change based on the destination IP address. Instead of using a static encryption key, the system dynamically selects different encryption schemes from a plurality of available schemes, making it difficult for attackers to crack keys or perform man-in-the-middle attacks since the encryption method adapts to each transmission target.
Solution Approach 2:
The system changes the encryption parameter (encryption scheme) based on the destination IP address. The encryption module selects from multiple encryption schemes depending on the target, thereby transforming the encryption approach from a fixed parameter to a variable one that adapts to different transmission scenarios, enhancing security against replay attacks and key cracking.
2Ease of operation
If encryption keys are valid for extended periods (e.g., one year), then certificate validation is simplified, but the window for potential key compromise and unauthorized access increases
Solution Approach 1:
The encryption scheme dynamically changes based on the destination IP address, creating a new effective encryption key for each transmission session. This dynamic approach reduces the vulnerability window from years (static key validity) to essentially real-time, as each encryption scheme is targeted-specific and can be rotated without requiring long-term key management.
Solution Approach 2:
The patent segments the encryption approach by destination IP address, creating separate encryption schemes for different targets. This segmentation means that even if one encryption scheme is compromised, other schemes remain secure, effectively limiting the impact of any single key compromise to a specific destination rather than exposing all communications.
3Device complexity
If a single encryption scheme is used for all transmissions, then the system is simpler to implement, but it becomes vulnerable to targeted attacks on specific IP addresses
Solution Approach 1:
The patent applies local quality by assigning different encryption schemes to different destination IP addresses. Each transmission target receives a customized encryption approach tailored to its specific address, making targeted attacks on specific IPs ineffective since each has its own encryption scheme. This localizes the security properties to match the local characteristics of each destination.
Solution Approach 2:
The encryption parameter (scheme selection) changes based on the destination IP address. The system maintains relatively simple implementation by using a lookup-based approach where the destination IP determines the encryption scheme, balancing complexity with enhanced security against targeted attacks through parameter variation.
