Applying security architecture to industrial network protocol

Control Protocols based on IP have attracted attention in recent years. While many protocols apply IP to Information networks and apply independent protocols to the field networks, there are protocols applying IP to field networks like FF-HSE. Such protocols enable seamless end-to-end communication between devices. Meanwhile, it becomes necessary to introduce network security architecture. It has been proposed security architecture which is suitable for field network. However, it hasn´t been considered to apply it to the actual protocol. So if it would be applied to the actual protocol directly, it might cause function duplication. This paper proposes the optimal design of the security architecture when it would be applied it to FF-HSE.
