Abstract
Embodiments provide methods of conducting operations with an implantable medical device (IMD) and an external controller device for performing authentication operations. In some embodiments, the method comprises: generating or storing an authentication data structure in the external controller device for over-the-air communication between the external device and the IMD, wherein the authentication data structure is generated by: (1) removing attribute fields from a first digital certificate and adding a public key of the external controller device to form an intermediate data structure; (2) creating a digital signature of the first intermediate data structure using a second digital certificate of an issuing certificate authority (CA); and (3) forming the authentication data structure by combining the intermediate data structure, the created digital signature, a public key of the issuing CA, and a digital signature of the public key of the issuing CA created using a third digital certificate of a root CA.
