Abstract
Systems and methods for secure team-based communication on existing wireless mesh networks are disclosed. In an example network with multiple network nods, a headend system designates a first network node and a second network node as a sub-group of nodes, generates a sub-group encryption key that is unique to the sub-group of nodes, and transmits the sub-group encryption key and the sub-group node list and to the first node and the second node. The first node encrypts an application layer message with the sub-group encryption key and sends the message to the second node. The second node decrypts the application layer message with the sub-group encryption key and performs an action based on the message.
