Abstract

Methods and systems for securely exchanging cipher keys between an implantable device and an external device are described. An example method includes: receiving an authorization request from the external device, wherein the authorization request is a request to receive a first cipher key of a cipher key exchange; receiving an indication that a magnet is detected relative to the implantable device, wherein the indication signifies a secure environment for communication between the implantable device and the external device; and after receiving the authorization request and the indication of a detected magnet, generating a first cipher key transmittal instruction, wherein the first cipher key transmittal instruction instructs the first cipher key to be transmitted to the external device by the implantable device.
