Abstract
Systems for communicating over a network and between two or more network connected devices. In particular, the disclosure reveals systems which include a first node having a first node message sequence counter, a second node having a second node message sequence counter, and wherein the second node is configured to synchronize the first node message sequence counter based on the second node message sequence counter.
Claims19
A network system for secured messaging, comprising:
- a first node having a first node message sequence counter;
- and
- a second node having a second node message sequence counter;
- and
- wherein the first node is configured to synchronize the first node message sequence counter in response to a response message received from the second node;
- wherein the response message received from the second node includes the second node message sequence counter;
- wherein the first node ignores any further response messages after receiving the response message from the second node;
- wherein the first node resumes normal communication with other nodes using the synchronized first node message sequence counter.
A network system for secured messaging, comprising:
- a first node having a first node message sequence counter;
- a second node having a second node message sequence counter;
- and
- a server in communication with the first node and the second node;
- and
- wherein the first node is configured to synchronize the first node message sequence counter with the second node message sequence counter without the first node, the second node or both the first node and second node receiving an updated session key from the server;
- wherein the first node is configured to synchronize the first node message sequence counter in response to a first response message received from the second node;
- wherein the first response message received from the second node includes the second node message sequence counter;
- wherein the first node ignores any further response messages after receiving the response message from the second node;
- wherein the first node resumes normal communication with other nodes using the synchronized first node message sequence counter.
A method of synchronizing a node message sequence counter of a rebooting node of a plurality of nodes, the method comprising:
- a first node outputting a multicast message to a plurality of nodes;
- and
- a second node of the plurality of nodes sending its node message sequence counter to the first node;
- and
- wherein there is in response to receiving the multicast message, a response message sent by the second node which synchronizes the node message sequence counter of the first node with the node message sequence counter of the second node;
- wherein the first node ignores any further response messages after receiving the response message from the second node;
- wherein the first node resumes normal communication with other nodes using the synchronized node message sequence counter.
