MoCA Network Protected Setup for Secure Node Admission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks, such as MoCA networks, lack a secure, reliable, and efficient method for adding new nodes, leading to inadequate security and inefficiencies in network access.
Innovation Solution
The system allows new nodes to securely join an existing network by detecting a Beacon signal, exchanging protected setup parameters, and determining compatibility, with the network coordinator managing password exchange and node admission based on privacy settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new nodes are added to the network without protected set-up procedures, then network expansion and adaptability are improved, but network security and reliability deteriorate
Solution Approach 1:
The patent implements protected set-up procedures that are executed before new nodes are fully integrated into the network. This preliminary action includes establishing secure connections, exchanging cryptographic credentials, and verifying node authenticity prior to network admission, thereby ensuring security is established in advance rather than retroactively
Solution Approach 2:
The patent introduces a network coordinator as an intermediary entity that mediates the admission process between new nodes and existing network members. The coordinator manages protected set-up procedures, verifies node credentials, and controls the timing of network integration, thereby decoupling the security verification process from the network expansion process
2Reliability
If protected set-up procedures are implemented for new node addition, then network security is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent enables new nodes to perform self-registration and self-configuration during the protected set-up process. Nodes automatically generate cryptographic credentials, establish secure connections with the network coordinator, and configure their network parameters without requiring manual intervention, thereby reducing operational complexity despite the enhanced security procedures
Solution Approach 2:
The patent designs the protected set-up procedures to handle multiple node types and network scenarios through a unified framework. The same cryptographic protocols and coordination mechanisms are applied regardless of the specific node configuration or network topology, thereby reducing the need for multiple specialized procedures and lowering overall system complexity
3Reliability
If protected set-up procedures are implemented for new node addition, then network security is improved, but the time required for node admission increases
Solution Approach 1:
The patent performs cryptographic credential exchange and security verification as preliminary actions during the protected set-up phase, before the node becomes fully operational in the network. By completing these time-consuming security procedures in advance, the actual network integration and data transmission can begin immediately without repeated security checks, thereby reducing overall admission time
Solution Approach 2:
The patent maintains continuous communication channels between the new node and the network coordinator throughout the protected set-up process. Rather than interrupting the admission workflow for separate security verification steps, the security procedures are embedded within the continuous node registration flow, eliminating idle time and maintaining productive action throughout the admission process

AI summary
Systems and methods are disclosed for securing a network, for admitting new nodes into an existing network, and/or for securely forming a new network. As a non-limiting example, an existing node may be triggered by a user, in response to which the existing node communicates with a network coordinator node. Thereafter, if a new node attempts to enter the network, and also for example has been triggered by a user, the network coordinator may determine, based at least in part on parameters within the new node and the network coordinator, whether the new node can enter the network.
