Dynamic Access Tokens Using Multi-Storage Credential Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access tokens are vulnerable to leakage and impersonation attacks if not properly secured, compromising the security and integrity of data in network environments.
Innovation Solution
Dynamically generate access credentials off-line using a token template that requires contributions from multiple object-based storage devices, ensuring each device provides unique inputs to populate the token, making it resilient to impersonation attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static access tokens are used, then implementation is simple, but security is compromised due to token leakage vulnerability
Solution Approach 1:
The patent transitions from static access tokens to dynamic access tokens that are generated on-demand and expire after use. The token generation system dynamically creates unique tokens for each authentication request, ensuring that even if one token is leaked, it cannot be reused. This dynamic approach resolves the security vulnerability of static tokens while maintaining implementation feasibility through standardized token protocols.
Solution Approach 2:
The patent implements short-lived access tokens that are generated temporarily and invalidated after use or expiration. Each token is designed to be used once or within a limited time window, making leaked tokens useless for long-term compromise. This disposable token approach maintains security without requiring complex long-term key management infrastructure.
2Reliability
If dynamically generated access tokens are used, then security against leakage is improved, but vulnerability to impersonation attacks remains
Solution Approach 1:
The patent segments the token generation process into multiple independent components: authentication service, token generation service, and validation service. Each component operates independently with defined interfaces, allowing security policies to be enforced at each stage. The token itself is segmented into multiple claims (user identity, permissions, expiration) that can be independently validated, preventing impersonation even if parts of the token structure are known.
Solution Approach 2:
The patent implements feedback mechanisms where the token generation system receives authentication results and validates token requests against current system state. The validation service continuously checks token authenticity against the issuing authority's current policies, providing real-time feedback that prevents impersonation attacks. This feedback loop ensures that even dynamically generated tokens cannot be successfully impersonated without proper authentication.
3Object-affected harmful factors
If multiple storage devices contribute to token generation, then security against impersonation is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary token generation service that coordinates between multiple storage devices and the authentication system. This intermediary manages the complex logic of distributing token generation across multiple devices, handling device selection, load balancing, and failure recovery. The intermediary abstracts the complexity from the authentication and validation processes, allowing multiple storage devices to contribute to token security without proportionally increasing overall system complexity.
Data Source
AI summary
Systems and methods are described herein for improving security in network environments by dynamically generating access credentials off-line that are resilient to impersonation attempts. For example, the system may receive, at a local token service, a first external request from a remote token service for a first dynamically generated token. The system may retrieve, at the local token service, a first token template for the remote token service. The system may, based on the first token template, select a first object-based storage device and a second object-based storage device. The system may transmit, by the local token service, a first internal request to the first object-based storage device and a second internal request to the second object-based storage device. The system may populate the first token template with the first token portion and the second token portion to generate the first dynamically generated token.
