Security- and safety-critical cyber-physical systems

摘要

Cyber-physical systems (CPSs) are physical embedded systems with enhanced operations for monitoring, coordination, control, and integration by a computing and communication core.Examples of CPSs include transportations systems,medical systems,and manufacturing systems.A CPS can be security-critical, safety-critical, or both. A CPS communicating with the outside world and thus opening an attack vector through the communication channel is considered to be a security-critical CPS. On the other hand, a CPS is considered to be safety-critical if it can harm its environment, eg, a malfunctioning autonomous vehicle might harm its passengers.A CPS dealing with both security and safety concerns is considered to be a security- and safety-critical CPS.
