Epoch-Based HTTP Authorization Tokens Against Replay Attacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face inefficiencies in authentication and authorization processing, requiring significant resources and being prone to replay attacks and unauthorized data theft.
Innovation Solution
A distributed security system is implemented where processing nodes receive requests, determine authorization, and generate or verify authentication data using epoch-based encryption to minimize resource usage and prevent fraudulent access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authentication and authorization analysis are performed to determine user legitimacy, then security reliability is improved, but processing time and resource consumption increase
Solution Approach 1:
The system performs preliminary authentication and generates authorization tokens before the actual resource access request. The authorization data is prepared in advance and attached to subsequent requests, eliminating the need for repeated authentication analysis during resource access operations.
Solution Approach 2:
The system creates authorization tokens that are copies of the authenticated user's identity and permissions. These tokens can be verified without requiring the original authentication process, allowing fast validation of user legitimacy through token verification rather than repeated authentication analysis.
2Ease of operation
If authentication and authorization data are stored and transmitted for user verification, then authorization functionality is improved, but vulnerability to replay attacks and data theft increases
Solution Approach 1:
The system implements epoch-based time windows where authorization tokens are only valid for specific time periods. Each epoch represents a discrete time window, and tokens generated in one epoch cannot be replayed in another epoch, preventing replay attacks while maintaining authorization functionality.
Solution Approach 2:
The system changes the temporal parameter of authorization data by embedding epoch information and validity periods in tokens. This transforms static authorization data into time-dependent data that automatically expires, reducing the window of opportunity for replay attacks and data theft.
3Reliability
If centralized security processing is implemented within the enterprise network, then security control is improved, but resource consumption and system complexity increase
Solution Approach 1:
The system extracts the authentication and authorization processing functions from the enterprise's internal network infrastructure and implements them as external security services. This separates security control from the core business systems, reducing internal system complexity while maintaining centralized security management.
Solution Approach 2:
The system introduces external security service providers as intermediaries between users and enterprise resources. These intermediaries handle authentication and authorization processing, acting as a buffer that simplifies the enterprise's internal systems while maintaining security control through standardized token verification.
Data Source
AI summary
Systems, methods and apparatus for a distributed security that provides authentication and authorization management. The system can include an epoch processor that is used to validate authentication and authorization data that is valid only for an epoch. The epoch processor can maintain a public key that can be used to decrypt the authentication and authorization data during the epoch that the key is valid. The epoch processor can receive a new public key during each epoch. The epoch processor can also determine if the authentication or authorization data was fraudulently generated based on the contents of the data, and verifying whether the data is valid for the epoch in which it was decrypted.
