What is the duration of the CIK timer?

Explanation:
Four hours. The Change In Key (CIK) timer controls how long the active crypto key remains in use before the radio automatically initiates a key change. Four hours provides a practical balance: it limits the window of exposure if a key were compromised, while not interrupting normal operations with overly frequent re-keying. Shorter intervals would add unnecessary re-key overhead, and longer intervals would extend the risk period during extended missions.
