A system and method for securely authenticating a data exchange session with an implantable medical device is presented. A crypto key uniquely associated with an implantable medical device is defined to authenticate data during a data exchange session. A secure connection is established from an external source with a secure key repository securely maintaining the crypto key. Authorization to access data on the implantable medical device is authenticated by securely retrieving the crypto key from the secure key repository.

What is claimed is: 1. An apparatus for securely authenticating a data exchange session with an implantable medical device, comprising: an external device comprising a key generator configured to dynamically generate a crypto key for each data exchange session with an implantable medical device; the external device configured to establish an inductive telemetric link to the implantable medical device and to download the crypto key to the implantable medical device through the inductive telemetric link for each data exchange session; the external device configured to then transact the data exchange session with the implantable medical device through a long range telemetric link authenticated with the crypto key. 2. An apparatus according to claim 1, further comprising: an authentication component configured to employ the crypto key during the data exchange session, comprising at least one of: a command authenticator configured to authenticate commands exchanged through the external device with the implantable medical device and; a data integrity checker configured to check the integrity of the data received by and transmitted from the external device; and a data encrypter configured to encrypt the data received by and transmitted from the external device. 3. An apparatus according to claim 1, wherein the external device comprises a programmer. 4. An apparatus according to claim 3, wherein the crypto key is provided from the programmer to a repeater. 5. An apparatus according to claim 1, wherein the external device comprises a patient designator. 6. An apparatus according to claim 1, wherein the crypto key comprises at least one of a 128-bit crypto key and a symmetric crypto key. 7. An apparatus according to claim 1, wherein the implantable medical device comprises at least one of an implantable cardiac device, neural stimulation device, and drug therapy dispensing device. 8. An apparatus according to claim 1, wherein the implantable medical device maintains patient health information in an encrypted form. 9. An apparatus according to claim 1, wherein the implantable medical device maintains patient health information in an unencrypted form and is accessible in the unencrypted form exclusively through a short range telemetric connection. 10. An apparatus according to claim 1, wherein the long range interface is augmented using one or more repeaters.
