Solution Overview

Problem

Conventional authentication protocols for remote terminals are resource-intensive, require user intervention for key management, and lack automated validation, leading to variability in security and operational efficiency across multiple remote terminals.

Innovation Solution

The method involves generating key pairs on remote terminals, using these keys to create secure communication requests that include public keys, and transmitting these requests to terminal management servers for registration and validation, enabling automated authentication and key management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional authentication protocols are used for remote terminals, then security validation can be achieved, but resource consumption increases and user intervention is required for key management

Engineering Contradiction:

Improveauthentication securityVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system enables automated key management where the terminal management server automatically generates, distributes, rotates, and resets cryptographic keys without requiring user intervention. The server autonomously manages the complete key lifecycle including generating key pairs, distributing public keys to terminals, rotating expired keys, and resetting compromised keys, thereby eliminating manual operations while maintaining security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal management server performs preliminary key generation and distribution before authentication is needed. Keys are pre-configured and stored securely in the server, allowing rapid authentication responses without requiring real-time key generation or user intervention during critical authentication moments.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If conventional authentication protocols with multiple keys are used, then security can be maintained, but operational efficiency decreases due to resource-intensive tasks

Engineering Contradiction:

ImprovesecurityVSAvoidoperational efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system transitions from managing multiple separate cryptographic keys to a streamlined single-key architecture where each terminal has one primary authentication key. This parameter change simplifies the authentication process, reduces computational overhead for key management operations, and improves operational efficiency while maintaining security through the server's ability to rapidly generate and rotate keys as needed.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The complex key management operations are extracted from the terminal devices and centralized in the terminal management server. The server handles all resource-intensive tasks including key generation, storage, rotation, and reset operations, allowing terminals to perform only lightweight authentication verification, thereby improving overall system productivity.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If conventional authentication protocols are used, then some level of security is achieved, but security consistency varies across multiple remote terminals

Engineering Contradiction:

Improveauthentication securityVSAvoidsecurity consistency

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The terminal management server provides a universal key management solution that serves all remote terminals in the system. The server implements consistent key generation algorithms, uniform key distribution protocols, and standardized rotation policies across all terminals, ensuring that every terminal receives the same level of security protection regardless of its location or function within the network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements continuous monitoring and automated key rotation based on expiration detection. The server tracks key validity periods for all terminals and automatically initiates key rotation before expiration, ensuring consistent security posture across the fleet. The server also monitors for compromised keys and can rapidly reset them system-wide, maintaining uniform security standards.

AI summary

A method for facilitating automated authentication of a plurality of remote terminals is disclosed. The method includes generating, via a remote terminal, a key pair, the key pair including a public key and a private key that is persisted within the remote terminal; generating, via the remote terminal, a communication request by using the key pair, the communication request including the public key; transmitting, via the remote terminal using an application programming interface, the communication request to a terminal management server; registering, via the terminal management server, the remote terminal to a terminal database by using information in the communication request; persisting, via the terminal management server, the public key from the communication request to a persistent object storage repository; and generating, via the terminal management server, a response to the communication request, the response including status information and configuration information.
