One-Time Password Generator for Secure Computer System Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preventing unauthorized access to computer systems, such as two-factor authentication, are ineffective in Windows safe mode and can be costly for ordinary users, leaving systems vulnerable to malicious access.
Innovation Solution
A method utilizing a one-time password generator that produces a cipher text from user/system numbers, valid dates/times, and random numbers, which is then decrypted and verified for secure login, with monitoring to restrict usage duration or counts, ensuring secure access even in Windows safe mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-factor authentication using hardware devices is implemented, then security is increased, but device cost and complexity increase
Solution Approach 1:
The patent creates a software-based copy of hardware authentication functionality through virtual machine technology. The authentication key and security functions are replicated in the virtual machine environment, eliminating the need for physical hardware devices while maintaining security. This allows the system to achieve hardware-level security without the cost and complexity of actual hardware tokens or smart cards.
Solution Approach 2:
The patent replaces mechanical hardware authentication devices with a software-based virtual machine system. Instead of using physical hardware tokens, smart cards, or biometric devices, the authentication mechanism is implemented through virtualized software components that run within the operating system, substituting mechanical systems with electronic/software equivalents.
2Reliability
If two-factor authentication using hardware devices is implemented, then security is increased, but ease of operation decreases
Solution Approach 1:
The virtual machine authentication system operates automatically in the background without requiring user intervention to manage physical hardware devices. The authentication key is automatically generated, stored, and utilized by the virtual machine environment, eliminating the need for users to manually handle hardware tokens, insert smart cards, or perform complex authentication rituals. The system serves itself by automatically managing the authentication process.
3Ease of operation
If traditional password protection is used, then ease of operation is maintained, but security deteriorates
Solution Approach 1:
The patent merges traditional password authentication with virtual machine-based cryptographic authentication. The system combines the simplicity of password entry with the security of hardware-level cryptographic keys stored in the virtual machine environment. This integration allows users to maintain easy password-based operation while benefiting from the enhanced security of virtualized hardware authentication mechanisms.
