Zone-Specific Key Distribution for Distributed Authentication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed computing environments face challenges in balancing security and efficiency, particularly in managing vulnerabilities across multiple zones, where a security breach in one zone can compromise others, and existing authentication methods are cumbersome and prone to unauthorized access.
Innovation Solution
Implementing a distributed computing environment with multiple password verification systems, each with its own key distribution system, using password-based key derivation functions and zone-specific keys to prevent unauthorized access across zones, and employing a two-component authentication process with time and salt-based signatures to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single centralized authentication system is used across multiple zones, then ease of operation is improved, but security is worsened because a breach in one zone compromises all other zones
Solution Approach 1:
The patent divides the authentication system into zone-specific password verification systems, each with its own key distribution system and verification database. This segmentation ensures that a security breach in one zone cannot compromise other zones, as each zone operates independently with its own cryptographic keys and verification processes.
Solution Approach 2:
Each zone is configured with local authentication credentials and key pairs specific to that zone. The password verification systems use zone-specific keys derived from user passwords combined with zone identifiers, ensuring that authentication security is tailored to each zone's requirements and that compromises remain localized.
2Reliability
If zone-specific authentication systems are implemented for each zone, then security is improved through isolation, but device complexity increases due to multiple key distribution systems
Solution Approach 1:
The patent implements a universal authentication framework where each password verification system can handle multiple zones and services. The key distribution system generates zone-specific keys using a standardized process that works across all zones, reducing the need for completely separate systems while maintaining security isolation.
Solution Approach 2:
User credentials are pre-configured with multiple zone-specific key pairs before deployment. The key distribution system generates and distributes zone-specific authentication credentials in advance, so that when users access different zones, the authentication process is already prepared and does not require complex real-time key generation or system reconfiguration.
3Ease of operation
If traditional password verification methods are used, then ease of operation is maintained, but vulnerability to unauthorized access and interception increases
Solution Approach 1:
The patent replaces traditional password-based authentication with a cryptographic system using public-key infrastructure and hash-based message authentication codes (HMAC). Instead of transmitting or storing plain passwords, the system uses cryptographic key pairs where the private key remains on the user's device and the public key is used for verification, eliminating the vulnerabilities of traditional password systems while maintaining ease of use.
Solution Approach 2:
The patent introduces cryptographic hash functions and HMAC as intermediaries between the user's password and the verification system. The password is transformed into a cryptographic key through a key derivation function, and authentication is verified using HMAC with zone-specific keys. This intermediary layer prevents direct exposure of passwords and protects against interception and database breaches.
Data Source
AI summary
A credential, such as a password, for an entity is used to generate multiple keys. The generated keys are distributed to credential verification systems to enable the credential verification systems to perform authentication operations. The keys are generated such that access to a generated key allows for authentication with a proper subset of the credential verification systems. Thus, unauthorized access to information used by one authentication system does not, by itself, allow for successful authentication with other authentication systems.
