First Claim
1. A system for confirming identity and authority by a patient medical device, comprising:
- master credentials issued to a requesting device and an implantable medical device from an authorizing agent comprising a public key of the authorizing agent and a digital signature of a root certification authority;
a public key of the root certification authority provided to the implantable medical device;
requesting device credentials issued to the requesting device from the authorizing agent comprising a public key of the requesting device and a digital signature of the authorizing agent;
identification credentials provided to the implantable medical device comprising the requesting device credentials and a digital signature of the requesting device; and
the implantable medical device configured to;
check the digital signature of the root certification authority using the public key of the root certification authority;
check the digital signature of the authorizing agent in the requesting device credentials using the public key of the authorizing agent in the master credentials of the implantable medical device; and
check the digital signature of the requesting device in the identification credentials using the public key of the requesting device in the requesting device credentials;
wherein programming of the implantable medical device is only permitted upon verification of the digital signature of the authorizing agent and verification of the digital signature of the requesting device.

Abstract
A system and method for confirming identity and authority by a patient medical device is provided. Master credentials are issued to a requesting device and a receiving device from an authorizing agent. The master credentials include a public key of the authorizing agent and a digital signature of a root certification authority. Device credentials are issued to the requesting device from the authorizing agent. The device credentials include a public key of the requesting device and a digital signature of the authorizing agent. Identification credentials are provided to the receiving device and include the device credentials and a digital signature of the requesting device. The requesting device is authenticated. The digital signature of the authorizing agent in the device credentials is checked using the public key of the authorizing agent in the master credentials of the receiving device. The digital signature of the requesting device in the identification credentials is checked using the public key of the requesting device in the device credentials.
