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 whether a coded proximity telemetry signal is being received;
- transmitting, via distance telemetry, information regarding an encryption key;
- determining 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 if the distance telemetry communication contains information encrypted according to the encryption key.
An implantable medical device, comprising:
- a receiver module;
- a transceiver module configured to transmit, via distance telemetry, information regarding an encryption key;
- and
- a processor configured to:
- determine whether a coded proximity telemetry signal is being received from another device by the receiver module,
- determine whether a distance telemetry communication containing information encrypted according to the encryption key is being received from the other device, and
- establish secure distance communication with the other device if the second distance telemetry communication contains information encrypted according to the encryption key.
A system, comprising:
