The cyber-physical systems are the combination of computational elements and physical entities that can interact with humans through many modalities. The security includes the malicious attempts by adversary that disrupts or destructs the functions of physical systems that affects infrastructure, businesses, and routine human life. The research in cyber-physical systems is in its infantry. The work requires the development of security models at cloud interacting with physical systems. The current research discusses four parts. The security requirements in the future engineering systems includes the state of security in cloud cyber-physical systems, security requirements in Hadoop distributed file systems and trust-based security model in sensor networks. Further, the proposed research develops the agent-based approach as an example of trust-based packet transfer. The approach keeps the each node’s current status. The results show that maintaining the ratings of each node, the trust can be calculated and eliminate the malicious node.
