Abstract
Techniques for secure team-based communication on existing wireless mesh networks are disclosed. In an example, a first network node receives a network encryption key from a headend system. The first network node receives a sub-group encryption key that is unique to a sub-group of nodes, a sub-group identifier, and a sub-group node list that lists the sub-group of nodes associated with the sub-group identifier. The first network node generates an application layer message for a second node of the sub-group of nodes at an application layer. The first network node encrypts the application layer message using the sub-group encryption key. The first network node generates a team packet that is addressed to a selected node and includes the encrypted application layer message and the sub-group identifier. The first network node encrypts the team packet using the network encryption key and transmits the encrypted team packet to the selected node.
