Cyber-physical systems (CPS)and theirInternet ofthings (IoT)components are repeatedly subject to various attackstargeting weaknesses in their firmware. For that reason emergesan imminent demand for secure update mechanisms that notonly include specific systems but cover all parts of the criticalinfrastructure. In this paper we introduce a theoretical conceptfor a secure CPS device update and verification mechanismand provide information on handling hardware-based securityincorporating trusted platform modules (TPM) on those CPSdevices. We will describe secure communication channels by stateof the art technology and also integrity measurement mechanismsto ensure the system is in a known state. In addition, a multi-levelfail-over concept is presented, ensuring continuous patching tominimize the necessity of restarting those systems

In modern internet landscapes, innovations in the internet ofthings (IoT) and cyber-physical systems (CPS) sector keep onsprouting. According to [1], nearly 20 percent of organizationsencountered at least one IoT-based attack in the recent threeyears and the forecast predicts a growth in expenses toimplement endpoint security from $240 million in 2016 to$631 million in 2021. Observing this development in the IoTand CPS market, the near future will sculpt those IoT andCPS landscapes with device automation gaining more groundin technology driven living environments.
