ABSTRACT: Cyber-Physical Systems, or Smart-Embedded Systems, are co-engineered for
the integration of physical, computational and networking resources. These
resources are used to develop an efficient base for enhancing the quality of
services in all areas of life and achieving a classier lifestyle in terms of a required
service’s functionality and timing. Cyber-Physical Systems (CPSs)
complement the need to have smart products (e.g., homes, hospitals, airports,
cities). In other words, regulate the three kinds of resources available: physical,
computational, and networking. This regulation supports communication
and interaction between the human word and digital word to find the required
intelligence in all scopes of life, including Telecommunication, Power
Generation and Distribution, and Manufacturing. Data Security is among the
most important issues to be considered in recent technologies. Because Cyber-Physical Systems consist of interacting complex components and middle-ware, they face real challenges in being secure against cyber-attacks while
functioning efficiently and without affecting or degrading their performance.
This study gives a detailed description of CPSs, their challenges (including
cyber-security attacks), characteristics, and related technologies. We also focus
on the tradeoff between security and performance in CPS, and we present
the most common Side Channel Attacks on the implementations of cryptographic
algorithms (symmetric: AES and asymmetric: RSA) with the countermeasures
against these attacks.
