Authentication Packaging System for Multi-Node Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing systems face issues with authentication credential processing in routing planes, where original authentication statements are lost during request transformation, leading to increased resource costs and security risks, and simple forwarding of credentials can result in unauthorized access.
Innovation Solution
A routing plane incorporates an authentication packaging system that combines client authentication information with an assertion of its identity, using entropy like a signing key, to create a tamper-proof package which is then attached to the request and validated by the target service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the routing plane terminates and transforms the request, then routing functionality is improved, but authentication information is lost
Solution Approach 1:
The patent introduces an authentication packaging system as an intermediary component between the routing plane and target services. This system packages authentication information from multiple sources (original request, routing plane identity, routing decisions) into a unified authentication package that preserves all authentication data while enabling the routing plane to perform its transformation function. The packaging system acts as a mediator that prevents information loss during the routing process.
Solution Approach 2:
The patent implements a nested structure where authentication information is packaged within layers: the original authentication statement is nested within a routing plane authentication layer, which is itself nested within the final authentication package. This nested doll approach allows multiple levels of authentication information to be contained within each other, preserving all authentication data through the routing transformation process.
2Productivity
If simple forwarding of credentials is used, then processing overhead is reduced, but security risks increase due to unauthorized access
Solution Approach 1:
The patent merges multiple authentication information sources into a single comprehensive authentication package. Instead of simple forwarding, the system combines the original client authentication, routing plane identity assertion, and routing decision information into one unified package. This merging approach maintains security by ensuring all necessary authentication data is present while still achieving efficient processing through single-package validation at the target service.
3Reliability
If authentication credential processing is performed in the routing plane, then authentication reliability is improved, but resource costs increase
Solution Approach 1:
The patent performs preliminary authentication packaging in the routing plane, where all authentication information is collected, validated, and packaged into a single authenticated package before forwarding to the target service. This preliminary action ensures authentication reliability is established early in the process, preventing the need for repeated authentication processing at downstream services and thereby reducing overall resource costs.
Solution Approach 2:
The patent creates a copied and condensed representation of authentication information in the form of the authentication package. Instead of processing raw authentication credentials at multiple levels, the system creates a compact authenticated copy that contains all necessary verification data, enabling efficient validation at the target service without repeating expensive authentication processing.
Data Source
AI summary
A routing plane includes an authentication packaging system that receives client authentication information, as part of a request from a requesting client that is to be routed to a target service. The authentication packaging system combines the authentication information with assertion information indicative of an assertion as to the identity of the routing plane, using an entropy, such as a signing key. The authentication package is attached to the request and is sent to the target service. The target service validates the authentication package based on the entropy and authenticates the routing plane based on the assertion information and performs authentication processing based on the authentication information.
