Character String Generation via XOR Coding for Cryptography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems in cryptography, statistics, simulation, and slot machines face vulnerabilities due to the limitations of key management, where keys must be frequently exchanged or renewed, leading to high maintenance efforts and security risks, especially against brute force attacks and statistical predictions.
Innovation Solution
A method where a first character string is stored and used to generate multiple second character strings through XOR coding and extension, ensuring the first string is not directly used, thereby enhancing security and reducing maintenance needs, while maintaining system integrity and unpredictability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If keys are frequently exchanged or renewed in cryptographic systems, then security against attacks is improved, but maintenance effort and system complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-generating a large pool of random numbers (first string) that is stored in the system. This pre-prepared pool eliminates the need for frequent key exchanges, as the system can draw from this existing reservoir to generate multiple second strings over time, thereby maintaining security while reducing maintenance complexity
Solution Approach 2:
The patent segments the key management process into two distinct components: a first string (pre-generated random number pool) and second strings (derived keys used in the system). This segmentation allows the system to maintain a secure, static first string while generating multiple usable second strings from it, reducing the frequency of key renewals and associated maintenance efforts
2Ease of operation
If the same key is reused for multiple message exchanges, then maintenance effort is reduced, but security vulnerability increases due to potential key deduction
Solution Approach 1:
The patent introduces an intermediary mechanism where the first string (stored random number pool) acts as a mediator between key generation and usage. Multiple second strings are derived from this single first string through XOR operations with counter values. This intermediary approach allows key reuse at the first string level while maintaining security through the transformation process, preventing direct key deduction attacks
Solution Approach 2:
The patent applies parameter changes by transforming the static first string into multiple different second strings through mathematical operations (XOR with counter values). This parameter transformation allows the system to maintain operational simplicity with a single stored key while generating diverse usable keys, balancing ease of operation with security requirements
3Device complexity
If a shorter key is used in encryption methods, then key management becomes simpler, but the key can be more easily deduced from encrypted messages
Solution Approach 1:
The patent moves the security burden to another dimension by using a very long first string (100 MB or more) instead of relying on key length in traditional encryption. This dimensional shift allows the use of shorter operational second strings while maintaining security through the entropy of the large first string pool, simplifying key management without compromising security
