Cyber-physical systems (CPSs) are physical embedded systems with enhanced operations for monitoring, coordination, control, and integration by a computing and communication core.[1] Examples of CPSs include transportations systems,[2] medical systems,[3] and manufacturing systems.[4] A CPS can be security-critical, safety-critical, or both. 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.[5] A CPS dealing with both security and safety concerns is considered to be a security-and safety-critical CPS. Finally, the paper proposes security solutions for data management systems by identifying various security vulnerabilities in internal security algorithms of such systems.[Extracted from the article]
