- State transitions (i. e. the lines between states) are labeled with < what causes the transition >/<
messages and events triggered by the transition>.
If there are multiple events or messages before the slash "/" separated by a comma, any of them can
cause a transition. If there are multiple events or messages listed after the slash, all of the specified
actions must accompany the transition.

6.12 TEK State Machine
The TEK state machine consists of six states and nine events (including receipt of messages) that can
trigger state transitions. Like the Authorization state machine, the TEK state machine is presented in
both a state flow diagram and a state transition matrix.. Shaded states in Figure 5-5 (Operational,
Rekey Wait, and Rekey Reauthorize Wait) have valid keying material and encrypted traffic can be
passed. The Authorization state machine starts an independent TEK state machine for each of its
authorized SIDs (SAIDs).
