Proximity signature for secure communication with implantable medical device

摘要

Systems, devices and methods employing coded magnetic fields or transfer of encryption key information via proximity telemetry are described. The systems, methods and devices help prevent or reduce unintended or unintentional distance telemetry communication between an external medical device and an implantable medical device.

主权项

1. A method of establishing secure communication between an implantable medical device and an external device, the method being performed by the implantable medical device and comprising:
determining, via a processor, whether a coded proximity telemetry signal is being received by a proximity telemetry module; transmitting, via distance telemetry by a distance telemetry module, information regarding an encryption key; determining, via the processor, whether a distance telemetry communication containing information encrypted according to the encryption key is being received; and establishing secure distance communication with the external device via the processor if the distance telemetry communication contains information encrypted according to the encryption key.
