Lab Wireless Power Charging Security – Objective This lab is designed to offer an introduction into the concept of Cyber-Physical System Security. The purpose of the experiment is for students to understand how randomness is utilized to achieve wireless power charge security in a CPS system. Introduction and Background Cyber-physical systems (CPS) are systems that contain computational elements and physical components; both the and the of the system interact with each “cyber” “physical” parts other. One, specific example of are implanted medical devices (IMD). A pacemaker is an CPS’s IMD that has many benefits; however, an issue of security arises.1 General protection schemes cannot be applied to the security measures taken need to be specifically integrated for all CPS’s; that particular the system. For instance, during the wireless power charging of a pacemaker, it is vulnerable to potential cyber attacks. A general protection scheme like cryptography would only be effective in the transfer of data; the wireless charging process is a transfer of electromagnetic energy.2 A solution for security in this case could be achieved through secret resonance frequency tuning.3 Wireless power charging depends on a sender and receiver matching resonant frequency. Hackers could attack a wireless charge if resonant frequency is static. If the frequency was only known to the sender and receiver, and it was unknown to an attacker then security would be achieved. The experiment in this lab will focus on generating a random, resonant frequency using logistic maps.
