Modern control systems are increasingly becoming decentralized in nature, where supervision and monitoring happens remotely. An attack on the control system can cause large scale economic impact and claim human lives. Security becomes an essential part for these systems. In the thesis, we solve a decentralized control problem by modeling it as a team. An agent directly observes certain state variables. Other members may communicate to the agent some information that are not observed by the agent. The objective of the team members is to optimize a common cost function under asymmetric information. In particular, we are interested in computing the optimal strategies that the agents must adopt for minimizing a common cost function. We show that the optimization problem for static team can be reduced to a convex quadratic program under certain information structure. We identify the optimal strategies if the agents have incomplete information of states or if certain links are broken. We show that the results derived for static team can be extended to solving dynamic team with partially nested information structure. By numerical simulation studies, we identify links that can be eliminated with minimum deterioration in overall performance. Elimination of redundant links can conserve internet bandwidth for faster communication, thus reducing the effect of delay. We also identify links that are critical for better performance and which must be protected from an attack by having longer keys in encryption and decryption.
