System for communication on a network
Systems for communicating over a network and between two or more network connected devices. In particular, the disclosure reveals systems which may utilize multicast communication protocols to facilitate secure communication among one or more network connected devices. A system for secured messaging may include a network system including a first server, a second server and a first node. Further, the first server is configured to authenticate the first node for secure multicast messaging, and the second server is configured to authenticate the first node for secure multicast messaging.
1. A system for secured messaging, comprising:
a network system including a first server, a second server, a first node, and a second node; and
wherein:
the first server is configured to authenticate the first node for secure multicast messaging;
the second server is configured to authenticate the first node for secure multicast messaging;
the first server is configured to authenticate the second node for secure multicast messaging;
the second server is configured to authenticate the second node for secure multicast messaging; and
the first node and the second node are configured to communicate on an out-of-band channel.
2. The system of claim 1 , wherein the first server is configured to authenticate the first node when the second server is not connected to the network.
3. The system of claim 1 , wherein the second server is configured to authenticate the first node when the first server is not connected to the network.
4. The system of claim 1 , wherein the first server, the second server and the node communicate using a secured multicast communication protocol.
5. The system of claim 1 , wherein the first server is configured to authenticate the first node by distributing a first session key, and wherein the second server is configured to authenticate the first node by distributing a second session key, wherein the second session key is different from the first session key.
6. The system of claim 5 , wherein the first node includes a public key credential configured to authenticate the first session key and the second session key.
7. A system for reconnecting nodes in a secure multicast network, comprising:
a first node configured to communicate using a secure multicast communication protocol on the secure multicast network; and
one or more nodes configured to communicate with the first node using the secure multicast communication protocol on the secure multicast network;
wherein when the first node disconnects from the secure multicast network and attempts to reconnect to the network, then the first node performs a network re-authentication;
wherein performing a network re-authentication further includes a request for a session key;
wherein the request for the session key includes outputting a request to a second node of the one or more nodes;
wherein the first node is configured to receive the session key from the second node; and
wherein the first node receives the session key from the second node on an out-of-band channel.
8. The system of claim 7 , wherein the request for a session key further includes outputting a request to a server and receiving a session key from the server.
9. The system of claim 8 , wherein if the received session key is not the latest session key, the first node sends a request for the latest rekey message.
10. The system of claim 7 , further comprising a first server connected to the secure multicast network configured to communicate with the first node and the one or more additional nodes, wherein the first node and the one or more additional nodes are configured to detect when the server disconnects from the network, and upon detection of the server disconnecting, the one or more nodes sends the latest session key.
11. The system of claim 10 , wherein the network re-authentication includes receiving the message outputted from the one or more nodes.
12. A method of communicating over a network, the method comprising:
connecting a plurality of nodes to a network; and
wherein:
the nodes are configured to communicate over the secure multicast network;
a disconnected node of the plurality of nodes performs a network re-authentication;
the network re-authentication includes receiving the latest session key;
the disconnected node receives the latest session key from another node of the plurality of nodes; and
the disconnected node is configured to receive the latest session key from another node of the plurality of nodes on an out-of-band network.
13. The method of claim 12 , wherein the disconnected node is configured to receive the latest session key from a first server connected to the secure multicast network.
14. The method of claim 12 , wherein the secure multicast network includes a first server and a second server, and wherein the disconnected node is configured to receive the latest session key from the second server if the first server is disconnected from the secure multicast network.
