Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication technologies, such as PUF, DUF, and PKI, face limitations in flexibility, adaptability, and security, particularly in handling complex authentication infrastructures and potential vulnerabilities to quantum computing, which restrict their ability to authenticate multiple entities dynamically and change encryption architectures.
Innovation Solution
The method involves modifying digital device behavior by entering modifier data into devices to produce unique channel values, enabling secure communication and encryption between devices with different IDs, and allowing for flexible authentication and encryption architectures without the need for additional hardware, using a system of modifiers and channels to manage device behaviors and secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PUF technology is used to authenticate devices through unique hardware behavior, then device identity security is improved, but adaptability to different authentication channels deteriorates
Solution Approach 1:
The patent implements dynamic device behavior modification by allowing devices to change their authentication responses based on modifier data. Instead of static PUF responses, the system generates different authenticated outputs for different channels by applying modifiers to the device behavior, enabling the same hardware to adapt to multiple authentication scenarios while maintaining security.
Solution Approach 2:
The system changes the parameters of device behavior by introducing modifier data that alters how the device responds to authentication challenges. By modifying the behavior parameters rather than the hardware itself, the system achieves adaptability across different authentication channels while preserving the security properties of the underlying hardware.
2Reliability
If DUF technology is used for authentication with device signatures and hash functions, then authentication security is improved, but architectural flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic behavior modification to DUF by allowing devices to alter their authentication responses through modifier data. This enables the authentication architecture to adapt to different scenarios without changing the core security mechanisms, resolving the contradiction between security and flexibility.
Solution Approach 2:
The system creates a universal authentication framework where the same device can participate in multiple authentication channels with different modifiers. The modifier mechanism allows a single device to fulfill multiple authentication roles, eliminating the need for separate authentication systems for each channel.
3Adaptability or versatility
If traditional PKI systems are used for authentication, then widespread compatibility is improved, but vulnerability to quantum computing deteriorates
Solution Approach 1:
The patent replaces traditional PKI cryptographic mechanisms with a behavior-based authentication system. Instead of relying on mathematical problems vulnerable to quantum computing (such as factoring and discrete logarithms), the system uses hardware-based behavior modification that is inherently resistant to quantum attacks while maintaining compatibility with existing authentication infrastructures.
4Reliability
If one authenticating hardware component is used per authentication channel, then authentication security is improved, but device complexity and cost deteriorate
Solution Approach 1:
The patent enables a single hardware component to serve multiple authentication channels by introducing behavior modification through modifiers. The same physical device can securely authenticate to multiple different channels by dynamically adjusting its behavior, eliminating the need for separate hardware components for each channel while maintaining security.
Solution Approach 2:
The system merges the functionality of multiple authentication components into a single device by combining the base authentication capability with a behavior modification mechanism. This consolidation allows one hardware component to perform the work of multiple components while maintaining the security properties of each individual channel.

AI summary
A modifier infrastructure that takes digital device behaviors and allows them to enact channel behaviors instead. This infrastructure preferably extends to address issues of channels connected to channels for controlling and managing identities, privileges, and the encryption and decryption of valuable information. Embodiments of the present invention provide methods for computer authentication—particularly for component authentication, human-component authentication, and/or network cryptography.
