Cryptographic Frame Encoding for Low-Overhead Secure Storage Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently managing data throughput, power consumption, and security, particularly in wireless networks where frequent session key refreshes introduce overhead and vulnerabilities to hacking due to periodic key changes.
Innovation Solution
The Intelligent Private Key (IPK) frame structure, which allows for flexible encryption scheme modifications, key length adjustments, and cipher directive changes, is introduced to enhance security and reduce overhead by dynamically changing encryption schemes, key operations, and key lengths with each communication, thereby thwarting hacking attempts and optimizing performance and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent session key refreshes are implemented to enhance security, then security is improved, but overhead increases and system performance deteriorates
Solution Approach 1:
The patent implements dynamic key selection where the cryptographic key changes based on the communication partner's identity rather than following a fixed periodic schedule. This dynamic approach allows the system to adapt key refresh frequency to actual security needs, improving security when necessary while minimizing overhead during stable communication sessions.
Solution Approach 2:
The system changes the parameter that determines key refresh from time-based (periodic intervals) to identity-based (communication partner). This parameter change allows the system to maintain security by using different keys for different partners while avoiding unnecessary key refreshes during continuous communication with the same partner, thus reducing overhead.
2Reliability
If periodic session key changes are implemented to prevent hacking, then security is improved, but data throughput decreases due to overhead
Solution Approach 1:
The patent replaces periodic key changes with dynamic key selection based on communication partner identity. This eliminates unnecessary key refresh overhead during continuous communication sessions while maintaining security through partner-specific keys, thereby preserving data throughput.
Solution Approach 2:
The patent extracts the essential security function (using different keys for different partners) from the periodic key refresh mechanism. By removing the periodic timing component, the system eliminates the associated overhead while retaining the core security benefit of partner-specific encryption.
3Reliability
If encryption scheme parameters are communicated via the network, then security configuration is improved, but power consumption increases
Solution Approach 1:
The patent performs key selection and encryption scheme configuration in advance based on the communication partner's identity before actual data transmission begins. This preliminary configuration reduces the need for frequent parameter communications during data transfer, thereby reducing power consumption while maintaining proper security configuration.
Solution Approach 2:
The system uses the communication partner's identity itself as the basis for key selection, eliminating the need for separate parameter negotiation and communication. The identity information serves dual purposes: identifying the partner and determining the encryption parameters, thereby reducing network overhead and power consumption.
