Solution Overview

Problem

The existing polling challenge-response mechanism for data collection in remote attestation is inflexible and inefficient, leading to security risks and increased message exchange.

Innovation Solution

Implementing a subscription-based data collection method where a remote attestation server delivers a subscription configuration to a network device, allowing the device to automatically feed back subscription information, reducing the need for repeated requests and enhancing flexibility and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If polling challenge-response mechanism is used for data collection, then the server can collect data from network devices, but the data collection mode is not flexible and requires repeated message exchanges

Engineering Contradiction:

Improvedata collection flexibilityVSAvoidmessage exchange complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a subscription-based feedback mechanism where network devices automatically send data to the server when events occur or data changes, eliminating the need for continuous polling requests and improving data collection flexibility

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The server delivers subscription configurations to network devices in advance, allowing devices to prepare and automatically respond when needed, reducing the complexity of repeated message exchanges

Inventive Principle:

Principle #10Preliminary action

2Productivity

If polling challenge-response mechanism is used, then data can be collected from network devices, but data collection efficiency is reduced due to repeated requests

Engineering Contradiction:

Improvedata collection efficiencyVSAvoidtime for repeated message exchanges

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The subscription mechanism enables continuous data flow from network devices to the server without interruption, eliminating the start-stop nature of polling requests and improving data collection efficiency

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Network devices automatically manage their own data transmission by subscribing to server requests and pushing data when events occur, eliminating the need for continuous server-initiated polling operations

Inventive Principle:

Principle #25Self-service

3Reliability

If polling challenge-response mechanism is used, then data collection can be performed, but security risks increase due to inflexible data collection mode

Engineering Contradiction:

Improvesecurity reliabilityVSAvoiddata collection flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The subscription-based feedback mechanism allows the server to receive data automatically when events occur, providing more flexible and secure data collection compared to polling, thereby improving security reliability

Inventive Principle:

Principle #23Feedback
