Abstract
In one example, a method includes transitioning, responsive to determining that a charging coil of wireless charger is in proximity of an implantable medical device (IMD) and by the IMD, from operating in a non-pairing mode into a pairing mode of a far-field wireless communication protocol. In this example, operating in the paring mode comprises: receiving, by the IMD and via a transceiver of the far-field wireless communication protocol, a public encryption key from another device that is different than the wireless charger; and determining, based on the public encryption key of the other device and a public encryption key of the IMD, a link encryption key for future communication between the IMD and the other device. In this example, the method further includes communicating, by the IMD and based on the link encryption key, with the other device via the far-field wireless communication protocol.
