Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing data throughput, power consumption, and security, particularly in wireless networks where session key refreshes introduce overhead and vulnerabilities to hacking due to periodic key changes.
Innovation Solution
The Intelligent Private Key (IPK) frame structure is introduced, which allows for flexible cryptographic key management by generating frames with fields defining cryptographic schemes, key operations, and key lengths, enabling frequent changes and hopping between encryption schemes, key lengths, and operations to enhance security and reduce overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If session key refreshes are implemented periodically in communication systems, then security is improved, but communication overhead increases and vulnerabilities to hacking arise due to periodic key changes
Solution Approach 1:
The patent implements dynamic key management where cryptographic keys and encryption schemes change continuously based on communication state rather than following fixed periodic schedules. The system dynamically selects from multiple key pools and adjusts key lifecycles based on real-time security requirements and communication patterns, eliminating the rigidity of periodic refreshes while maintaining security.
Solution Approach 2:
The system changes cryptographic parameters (key lengths, encryption algorithms, key pools) dynamically during communication sessions. Multiple key pools with different security levels and lifecycles are maintained, and the system selectively activates different keys based on communication context, threat levels, and performance requirements, rather than uniformly refreshing all keys periodically.
2Reliability
If frequent key changes are implemented to enhance security, then security is improved, but power consumption and processing overhead increase
Solution Approach 1:
The patent employs multiple key pools with varying security parameters and computational requirements. The system dynamically selects appropriate key pools based on security threats and communication contexts, using stronger encryption only when necessary. This selective parameter adjustment reduces unnecessary computational overhead and power consumption while maintaining security when needed.
Solution Approach 2:
Instead of uniformly applying frequent key changes across all communications, the system applies enhanced security measures selectively to high-risk or sensitive communications. Normal communications use standard key management, while critical communications trigger more frequent key refreshes or higher-security key pools, optimizing the balance between security and power consumption.
3Adaptability or versatility
If multiple cryptographic protocols and key management schemes are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal key management framework that handles multiple cryptographic protocols (symmetric, asymmetric, hybrid) through a single unified architecture. The system maintains multiple key pools that can serve different protocol requirements, and the key selection mechanism automatically matches the appropriate key type and pool based on the communication protocol being used, eliminating the need for separate key management systems for each protocol.
Solution Approach 2:
The key management system is segmented into independent key pools, each dedicated to specific cryptographic protocols or security levels. This segmentation allows the system to support multiple protocols without creating a monolithic complex structure - each pool can be managed independently with optimized parameters, and the selection logic simply routes to the appropriate pool based on protocol requirements.
