MoCA Push Button Configuration Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of installing multimedia networking systems in multiple rooms due to the need for rewiring and multiple devices, as well as the lack of user-friendly features in existing Multimedia over Coax Alliance (MoCA) standards, hinder efficient configuration and authentication of devices.
Innovation Solution
A push-button configuration method for MoCA devices that allows authentication and password determination through coordinated button presses within a specific time interval, using layer 2 management entity (L2ME) messages and protocol information elements (Protocol IE) over coaxial cabling, enabling secure and simplified network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional networking devices are installed in multiple rooms, then network coverage is achieved, but installation cost and complexity increase due to rewiring and multiple devices
Solution Approach 1:
The patent applies universality by enabling MoCA devices to perform multiple functions: existing coaxial cable infrastructure is reused for both traditional cable TV and MoCA networking, eliminating the need for separate wiring infrastructure. The network controller and authentication mechanism provide universal access across multiple rooms through the existing coaxial network, reducing the need for multiple dedicated devices per room.
2Adaptability or versatility
If MoCA standard is implemented, then device connectivity over existing coaxial cable is enabled, but usability is reduced due to lack of user-friendly configuration features
Solution Approach 1:
The patent implements self-service through automatic authentication and configuration. When a new MoCA device is connected, the network controller automatically detects the device, validates its authentication credentials, and configures network parameters without manual user intervention. The push-button configuration mechanism allows users to initiate connectivity by simply pressing a button on each device, with the system handling all complex authentication and configuration processes automatically.
3Reliability
If authentication mechanism is added to MoCA network, then security is improved, but configuration complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring authentication credentials on MoCA devices before they are deployed to the network. Each device contains pre-loaded authentication information that enables automatic validation during the connection process. The network controller maintains a pre-established authentication database, allowing rapid verification of device credentials without complex real-time authentication procedures.

AI summary
A first device coupled to a multimedia over coax alliance (MoCA) network may receive, from a second device, an indication that a configuration button on the second device has been pushed. The first device may receive, from a third device, an indication that a configuration button on the third device has been pushed. The first device may allow the second device to be authenticated on the MoCA network if the configuration buttons of the second and third devices were both pushed within a determined amount of time. The first device may prevent the second device from being authenticated on the MoCA network if the configuration button of the second device and the configuration button of the third device were not pushed within a determined amount of time. The indication from the third device may comprise a layer 2 management entity (L2ME) message or a Protocol Information element.
