Cyber Physical Systems: Analyses, challenges and possible solutions

It is becoming more difficult to protect the authentication of our data in today's world of smart living. On the one hand, we are able to live in smart homes and smart cities with ease. Even if we use the most complicated passwords, we can't be sure that the Internet of Things and the Internet of Everything are safe. One way to make sure people and things are safe is to use Multi-Factor Authentication. Also, a big and complicated system needs more efficient and robust solutions for real, and strong, security, so this is important. There are a lot of smart ways to solve problems today. For this reason, the internet of things is being used in every possible field or application. This new ecosystem, which is called Cyber Physical Systems, was built by IoTs. Cyber-Physical Systems use computing, communication, and control to make new technology or the next generation of engineered systems. In the last decade, there has been a lot of work done on cyber physical systems that we didn't expect. There have been a lot of threats, challenges, and important issues in the last decade. We have a big problem with the security of CPS because the basic blocks used to make them are very different. Even if we're talking about natural gas systems or transportation systems or other automated systems, they all have something to do with CPS, no matter what. These days, CPSs systems are used for energy, transportation, the environment, and health care, among other things. This article talks about a number of problems that need to be solved by researchers and scientists (working related to respective area, i.e., CPS). As a result, this article also talks about a partial survey of important research issues, and an overview of several research projects that have been done in the last decade by a number of different people to improve CPS. © 2021 The Authors
