Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for terminal authentication in electronic payment networks face challenges in securely verifying credentials and managing payloads, leading to potential security breaches and inefficiencies in transaction processing.
Innovation Solution
A network gateway system that verifies credentials from hardware tokens, associates them with database records, and downloads payloads securely to network devices, ensuring authentication and authorization through cryptographic keys and digital certificates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If credentials are verified and payloads are downloaded to network devices, then security and authentication reliability are improved, but system complexity increases
Solution Approach 1:
A network gateway is introduced as an intermediary component between network devices and the payload server. The gateway handles credential verification and payload distribution centrally, simplifying the overall system architecture while maintaining high authentication reliability. Multiple network devices can authenticate through a single gateway instance.
Solution Approach 2:
The network gateway performs multiple functions including credential verification, payload distribution, and authentication management. This multi-functional design reduces the need for separate dedicated components, thereby reducing system complexity while maintaining reliable authentication across multiple network devices.
2Object-affected harmful factors
If credential verification is performed before payload download, then security against fraud is improved, but processing time increases
Solution Approach 1:
Credentials are verified in advance before payload distribution occurs. The network gateway checks authentication credentials and validates device authorization status prior to downloading any payloads, ensuring that only authorized devices receive data. This preliminary verification prevents fraud while maintaining efficient processing by avoiding post-download security checks.
3Object-affected harmful factors
If payload distribution is restricted to verified devices, then data security is improved, but device accessibility decreases
Solution Approach 1:
The system implements a feedback mechanism where network devices provide authentication credentials and authorization information to the network gateway. The gateway uses this feedback to verify device legitimacy and control payload distribution. This ensures data security while maintaining ease of operation for authorized devices through automated verification processes.

AI summary
A network gateway includes a network interface and a computer processing unit. The network interface is configured to interface the network gateway with a first computer network. The computer processing unit is in communication with the network interface and is configured to receive from a network device, via the first computer network, a payload request that includes a first credential. The network device is configured to receive the first credential from a hardware token that is interfaced with the network device. The computer processing unit is configured to verify that, before the network device received the first credential from the hardware token, the first credential was associated with the network device in a database. The computer processing unit is configured to download a payload to the network device via the first computer network, after the verification.
