摘要：
Certain embodiments allow security keys to be maintained across mobile device states, or communication events, such as hand-over, and system idle and sleep power savings modes. By monitoring the lifetime of security keys, keys may be refreshed in an effort to ensure key lifetimes will not expire during a hand-over process or other device unavailable state.
