Evaluation of Secrecy Capacity for Next-Generation Leadless Cardiac Pacemakers
Cardiac pacemakers are implanted medical devices designed to regulate abnormal cardiac rhythms. In the case of traditional pacemakers, the leads are considered to be the weakest link. This study proposes the keyless physical layer security (PLS) method to provide information confidentiality for next-generation leadless cardiac pacemakers. Electromagnetic simulations and experimental measurements were performed to prove the hypothesis of the availability of positive secrecy capacity in the near proximity of the human body. The research also evaluates the insecure volume in three-dimensional space around the body representing all the eavesdropper positions from which the pacemaker can be eavesdropped... Read more
