Method and apparatus for MoCA network with protected set-up
View Patent ↗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.
