Key Establishment Algorithm for Secure Cyber Physical System to Prevent Cyber Attacks

Extensive research effort is going on to contribute to the Cyber Physical system (CPS). It will create a physical system capable of computation, communication and sharing information between physical devices. Physical devices become smart devices because of CPS. CPS are engineered systems that are built with sensors, microcontrollers which performs computation, communication, control, process and analysis of physical objects. CPS playing important role in smart cities, home automations and other applications. Due to resource constraints like low processing power and low storage space there is a lack of standard security mechanism which can provide adequate security in CPS. In the research paper, we proposed Key establishment mechanism which prevents CPS from cyber-attacks. The goal of this research paper are six -folds: i) to give a detailed overview of cyber physical system. ii) To study architecture of CPS. iii) To study different attacks on CPS with attack points. iv)Application areas of CPS v) security threats in CPS vi) Key establishment algorithm to prevent cyber-attacks in CPS.
