Cryptographic Hash Password Generation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to generate and regenerate truly random files consistently across different times, locations, and devices, and do not effectively link passwords to specific resources or authenticate users, making them vulnerable to cracking and management challenges.
Innovation Solution
A method that uses key files and cryptographic hash functions to generate and regenerate random files based on an alias, allowing for true randomness without relying on processor instructions, and linking the generated file to additional information for uniqueness and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If computers generate random strings using standard methods, then long and seemingly random strings can be produced, but the strings are pseudo random and vulnerable to cracking
Solution Approach 1:
The patent replaces the mechanical/computational random number generation system with a cryptographic hash-based system. Instead of using standard computer random number generators that produce pseudo-random output, the invention uses cryptographic hash functions (SHA-256, SHA-512) to generate truly random passwords from seed values, ensuring cryptographic security and eliminating the vulnerability of pseudo-random generation.
2Reliability
If passwords are made longer to withstand brute force attacks, then security against CPU attacks improves, but ease of memorization and typing deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism - a seed value (can be a simple phrase, date, or any user-friendly input) that is transformed through cryptographic hash functions into a long secure password. This intermediary approach allows users to provide easy-to-remember seeds while automatically receiving cryptographically secure long passwords, bridging the gap between ease of creation and security strength.
3Reliability
If true random number generation is implemented, then password security improves, but device complexity and hardware requirements increase
Solution Approach 1:
The patent substitutes complex hardware-based random number generation systems with software-based cryptographic hash functions. Instead of requiring specialized hardware random number generators or complex cryptographic libraries, the invention uses standard cryptographic hash algorithms (SHA-256, SHA-512) that can be implemented with minimal system complexity, achieving true randomness through mathematical hashing rather than hardware complexity.
4Adaptability or versatility
If passwords are regenerated consistently across different devices and times, then usability and security management improve, but ensuring true randomness at each generation becomes challenging
Solution Approach 1:
The patent uses a seed value as an intermediary that can be consistently provided across different devices and times. This seed (which could be a user-chosen phrase, date, or any identifiable value) serves as the input to the cryptographic hash function, ensuring that the same seed always produces the same password through deterministic hashing, enabling consistent regeneration while maintaining cryptographic security.

AI summary
Method for repeatable creation of random file enables to create and recreate random files at different places, different times and on different devices. Random files are based on aliases, which can contain any text, including specific information, such as serial number, start date, expiry date, etc. Random files can be used for generations of strong and unique passwords. The strength of the password doesn't depend on alias, so any alias will result in equally strong and unique password.Browser, using the method, would be able to register the user to any resource, by generating a password, using resource's URL as alias, and afterwards automatically log user in using same URL for generating the password again.Users can communicate securely by sending alias in plaintext together with ciphertext encrypted with password.IoT devices can establish master, slave, partner, alien relationship and communicate securely without human introduction.
