The described techniques address issues to achieve key agreement without the need to exchange separate key agreement messages and, consequently, meets the stringent starting time requirements for real-time control systems. This is achieved using a group-wide key counter, with each node storing the latest value of this counter that was observed via the last received secured message. This counter value increases monotonically, and nodes maintain synchronization by transmitting this counter value (or a representation of the counter value) in each secured message.

Each node within a membership group may request, or “challenge” other nodes with the same membership group at any time to verify their online status, and this online status may be maintained over time.
