Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating whitelists for IoT devices do not allow third parties to verify their accuracy, and there is a lack of mechanisms to check for unnecessary communications unintended by users.
Innovation Solution
A communication control system with a gateway that requests and creates a whitelist based on normal communication data from IoT devices, allowing verification of intended communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If whitelists are generated from normal state of already completed devices or apps, then whitelist generation is simple and quick, but third parties cannot verify the accuracy of the whitelists
Solution Approach 1:
The patent applies preliminary action by collecting communication information from IoT devices during their normal operation before the whitelist is finalized. The gateway accumulates communication logs and patterns during a monitoring period, then uses this pre-collected data to generate the whitelist. This allows third parties to verify the accuracy of whitelists by examining the collected communication data, while maintaining efficient generation through automated analysis of the accumulated information.
2Ease of operation
If manufacturer-defined whitelists are used blindly, then device setup is fast and easy, but unnecessary communications unintended by users cannot be detected
Solution Approach 1:
The patent implements feedback by continuously monitoring actual communication behavior of IoT devices and comparing it against the generated whitelist. The gateway collects communication information during device operation, analyzes patterns, and uses this feedback to verify whether communications match user-intended behavior. This feedback mechanism enables detection of unintended communications while maintaining easy device setup through automated whitelist generation based on observed normal behavior.
3Reliability
If third parties can verify whitelist accuracy, then communication security is improved, but system complexity increases due to additional verification mechanisms
Solution Approach 1:
The patent uses the gateway as an intermediary that bridges IoT devices and third-party verification systems. The gateway collects communication information from devices, generates whitelists based on this data, and provides the collected information to third parties for verification. This intermediary role enables third-party verification of whitelist accuracy without requiring direct access to device internals or complex verification infrastructure, thus improving communication security while managing system complexity through the gateway's coordination function.

AI summary
A communication control system includes a gateway and an IoT device connected to the gateway, wherein the gateway includes a request module configured to request, from the IoT device, information regarding normal communication performed by the IoT device, and a creation module configured to create a whitelist in which details of communication permitted for each IoT device are designated on a basis of the information regarding normal communication performed by the IoT device, which is transmitted from the IoT device, and the IoT device includes a transmission module configured to transmit the information regarding normal communication performed by the IoT device to the gateway in response to a request from the request module.
