Abstract
Methods, devices and systems are disclosed that provide for dynamically adjusting the valid lifespan of a session key for wireless communication sessions established between at least two medical devices. Adjusting the session key lifetime balances protecting the communications link so that it is not unnecessarily susceptible to eavesdropping by third parties or other interference while obviating the need for a user to repeatedly perform access control steps.
