Abstract: Critical infrastructure systems like power grid require an improved criticalin-formation infrastructure (CII) that can not only help in monitoring of thecrit-ical entities but also take part in failure analysis and self-healing.Efficient designing of a CII is challenging as each kind of communicationtechnology has its own advantages and disadvantages. Wired networks are highlyscala-ble and secure, but they are neither cost effective nor dynamic innature. Wireless communication technologies on the other hand are easy todeploy, low cost etc. but they are vulnerable to cyber-attacks. In order tooptimize cost, power consumption, dynamic nature, accuracy and scalability ahybrid communication network is designed in this paper where a portion of thecommunication network is built using wireless sensor networks (WSN) and therest is a wired network of fiber optic channels. To offer seamless opera-tionof the hybrid communication network and provide security a Secure Smart GridMonitoring Technique (SSGMT) is also proposed. The perfor-mance of the proposedhybrid CII for the generation and transmission sys-tem of power grid coupledwith the SSGMT during different cyber-attacks is tested using NS2 simulator.The simulation results show that the SSGMT for a joint power communicationnetwork of IEEE 118-Bus system performs better than the prevailing wirelessCIIs like Lo-ADI and Modified AODV.
