Platform Linking With Ephemeral Keys for Secure Value Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based value exchange systems rely on persistent credentials, exposing users to fraud, regulatory risks, and cyber-attacks, and introduce additional technical problems with conventional security measures.
Innovation Solution
A centralized key exchange platform uses universally unique ephemeral keys (UUEK) to facilitate credential-less exchanges between member platforms, establishing secure links without persistent credentials, enabling secure, flexible, and efficient cross-platform communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If persistent credentials are used for network-based value exchanges, then authentication and authorization can be established, but security risks including fraud, regulatory compliance costs, and reputational damage increase
Solution Approach 1:
The patent extracts the authentication function from persistent credentials and implements it through ephemeral credentials that are generated temporarily for each transaction. The core authentication mechanism is separated from long-term credential storage, eliminating the security risks associated with persistent credential exposure while maintaining reliable authentication through short-lived, transaction-specific credentials
Solution Approach 2:
The system transitions from static persistent credentials to dynamic ephemeral credentials that are generated and invalidated automatically. Credentials have temporary lifecycles with automatic expiration, creating a dynamic authentication system that adapts to each transaction context and automatically reduces exposure window for potential security breaches
2Object-affected harmful factors
If strict communication protocols and authentication schemes are implemented to address credential insecurity, then data security is improved, but network transaction overhead increases and complexity is introduced
Solution Approach 1:
The patent employs disposable ephemeral credentials that are inexpensive to generate and validate, replacing complex persistent authentication infrastructure. Each credential is designed for single-use or limited-use scenarios, eliminating the need for long-term credential management, revocation lists, and complex validation hierarchies while maintaining strong security through cryptographic proofs
3Adaptability or versatility
If persistent credentials are used for cross-platform communication, then user relationships can be linked across platforms, but user credentials are exposed at multiple points increasing vulnerability to network attacks
Solution Approach 1:
The patent introduces an intermediary credential verification system that enables cross-platform relationship linking without direct credential exposure between platforms. The intermediary validates ephemeral credentials and establishes relationships through trusted intermediation, allowing platforms to recognize user relationships across boundaries while keeping credential data isolated and never exposed to external platforms

AI summary
Various embodiments of the present disclosure provide a network linking technique that improves the functionality of a computer in various aspects. The techniques comprise responsive to an exchange request, receiving, originating from a member platform within the member computing ecosystem, a linking code request comprising a member-specific identifier corresponding to the member platform; providing, to an internal service, the linking code request to generate an ephemeral transport object storing a linking code and a link reference corresponding to the member-specific identifier and the linking code; providing the linking code to the member platform; receiving, originating from the another member platform within the member computing ecosystem, a linking request comprising the linking code; and authorizing, using the second member platform, the exchange request based on the linking code.
