The present invention provides systems and methods for supporting encrypted communications with a medical device, such as an implantable device, through a relay device to a remote server, and may employ cloud computing technologies. An implantable medical device is generally constrained to employ a low power transceiver, which supports short distance digital communications. A relay device, such as a smartphone or WiFi access point, acts as a conduit for the communications to the internet or other network, which need not be private or secure. The medical device supports encrypted secure communications, such as a virtual private network technology. The medical device negotiates a secure channel through a smartphone or router, for example, which provides application support for the communication, but may be isolated from the content.
