Epoch-Based Authentication for Replay Attack Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face inefficiencies in authentication and authorization processes, which are resource-intensive and prone to replay attacks, with unauthorized users potentially generating or stealing authentication and authorization data.
Innovation Solution
A distributed security provisioning system that processes requests externally to the network edge, using processing nodes to determine domain authorization, encrypting user data, and employing epoch-based key pairs to validate authentication data, thereby minimizing unnecessary transactions and preventing fraud.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple analysis of the request are performed to determine user authentication and authorization, then security reliability is improved, but processing time and resource consumption increase
Solution Approach 1:
The system performs preliminary authentication and authorization analysis by extracting domain authorization data from incoming requests before full processing. This preliminary check identifies requests that already contain valid authorization data, avoiding redundant analysis steps and reducing processing time while maintaining security.
Solution Approach 2:
The patent extracts domain authorization data from the request payload and separates it for dedicated processing. By taking out the authorization verification step and handling it independently with specialized data structures, the system reduces the complexity and time of overall request processing while ensuring thorough security checks.
2Reliability
If authentication and authorization data are maintained within the enterprise network, then security control is improved, but vulnerability to replay attacks increases
Solution Approach 1:
The patent introduces domain authorization data as an intermediary element that mediates between the client request and the enterprise security system. This intermediary data structure includes cryptographic elements and domain-specific information that prevent replay attacks while maintaining secure control, as it cannot be easily replicated or stolen without detection.
Solution Approach 2:
The system changes the parameters of authorization data by incorporating domain-specific identifiers, cryptographic signatures, and validity periods. These parameter changes transform static authentication data into dynamic, context-specific authorization tokens that are resistant to replay attacks while maintaining enterprise security control.
3Loss of energy
If external processing nodes are used for security provisioning, then resource usage within the enterprise is reduced, but system complexity increases
Solution Approach 1:
The patent segments the security provisioning system into external processing nodes that handle specific authorization tasks. By dividing the security function into independent, specialized nodes outside the enterprise network, the system reduces internal resource consumption while managing complexity through clear functional separation and standardized interfaces.
Data Source
AI summary
Systems, methods and apparatus for a distributed security that provides authentication and authorization management. The system can include an epoch manager that is used to generate authentication and authorization data that remain valid only for an epoch. The epoch manager can generate an epoch key pair that can be used to encrypt and decrypt the authentication and authorization data during the epoch that the key is valid. The epoch manager can also associate the contents of the data with the epoch in which it was created, so that at decrypting the epoch that the data was generated in can be identified.
