Loop-Based Authentication Flow for Secure Credential Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure communication systems are vulnerable to information theft and fraud due to reliance on federated credentials, where parties are often unknown to each other, leading to risks of hacking, eavesdropping, and replay attacks, and existing authentication measures are insufficient in preventing unauthorized use of credentials.
Innovation Solution
A loop-based authentication flow using a trusted, secure network where each node is connected via symmetric key encryption, allowing for the generation and exchange of a private session key (PSK) and secure transmission of federated credentials and private information, ensuring only the intended recipient can decrypt this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If federated credentials are used for authentication, then ease of operation is improved, but reliability deteriorates due to fraud and unauthorized use
Solution Approach 1:
The patent introduces a trusted third party (TTP) as an intermediary that issues digital certificates binding credentials to their legitimate owners. This TTP mediates between the credential user and the system, providing verification that the credential is authentic and authorized. The TTP signs credentials with its private key, creating a chain of trust that prevents unauthorized use while maintaining ease of operation.
Solution Approach 2:
The system performs preliminary authentication by verifying digital certificates before allowing credential use. The TTP pre-issues signed credentials to legitimate owners, and the system verifies these signatures before accepting credential presentation. This preliminary verification prevents fraud before it occurs, maintaining both security and operational ease.
2Productivity
If electronic verification of credentials is implemented, then productivity is improved, but object-affected harmful factors worsen due to hacking and eavesdropping risks
Solution Approach 1:
The patent replaces manual verification processes with cryptographic verification of digital signatures. Instead of mechanical checking of credential authenticity, the system uses mathematical verification of TTP-signed certificates. This substitution maintains high productivity while providing strong security against hacking and eavesdropping, as cryptographic verification is both efficient and highly secure.
Solution Approach 2:
The system applies preliminary anti-action by using cryptographic signatures to prevent hacking and eavesdropping before they can occur. The TTP's digital signature on credentials creates a tamper-evident binding that prevents unauthorized modification or interception. This preemptive cryptographic protection allows fast electronic processing while neutralizing security threats.
3Reliability
If secondary authentication checks are required, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple authentication factors into a single digital certificate issued by the TTP. Instead of requiring separate verification of credential authenticity, owner identity, and authorization, the TTP combines all these elements into one signed certificate. This consolidation maintains high reliability through comprehensive verification while reducing device complexity by eliminating the need for separate verification mechanisms.
Data Source
AI summary
A first party uses a secret key to encrypt information, which is then sent through an untrusted connection to a second party. The second party, however, cannot decrypt the information on its own, and it relays the encrypted information through a secure network. The secure network includes one or more nodes linking the first and second parties through one or more trusted connections (“hops”); each hop features uses of a shared secret key unique to that hop. The first party's connection to the network (domain) receives the information relayed through the secure network by the second party, it decrypts that information according to the secret key of the first party, and it then retransmits the decrypted information to the second party using the secure hops. Techniques are provided for sharing a private session key, federated credentials, and private information.
