Securing Wireless Communication in Cyber-Physical Systems and the Internet of Things: Addressing Security Challenges

Abstract

Safeguarding wireless communication in cyber-physical systems (CPS) and the Internet of Things (IoT) is important to stop hackers, data breaches, and system interruptions. Multiple security risks can affect these systems because they are linked together and depend on wireless communication methods. This essay looks at the security issues that mobile and internet-connected things (IoT) have and suggests ways to fix them. Two of the biggest problems are keeping data sent over wifi networks private and secure. You can keep data safe from people listening in or changing it by using encryption methods like Advanced Encryption Standard (AES) and Rivest Cipher (RC4). Furthermore, security tools like Public Key Infrastructure (PKI) and Digital Signatures can confirm the authenticity of devices and make sure that contact is safe. An additional problem is that radio communication methods can be attacked with tactics like man-in-the-middle and repeat attacks. You can make CPS and IoT systems safer by using secure methods like Transport Layer Security (TLS) and Secure Shell (SSH). Protecting radio contact is also important to avoid problems caused by denial-of-service (DoS) attacks. Employing intrusion detection systems (IDS) and firewalls can assist in finding and blocking harmful traffic, ensuring that communication stays unbroken. Lastly, protecting radio transmission in CPS and IoT is important to avoid many security risks. The security of CPS and IoT systems can be improved by using encryption methods, identification mechanisms, and safe protocols to keep data private, secure, and accessible.
