Motivation. The one-way authentication schemes, and the high computational and communicational costs can raise concern in two-way smart energy communications. Moreover, in the SEN communication, the integrity of messages is equally important as other security properties, since message integrity provides assurance that the messages are not been altered/forged in transit (or from the origin), as suggested by the National Institute Standards Technology (NIST) [27]. A loss of integrity may cause destruction of information and may lead to incorrect decision in smart energy network. However, the most of recently proposed schemes (e.g., [17], [19], [20], [21]), are vulnerable where an attacker can violate message Utility Server #1 Optical Network Utility Server #N with wireless (ZigBee, WiMAX, WiFi, etc.) or wired technologies, and distributed over many cities, or villages. Moreover, the physical security of the NAN gateway can xG xG NAN gateway NAN gateway be protected as it is located inside substation and locked from outsider access as recommended by [14] [30]. Note #1 ZigBee ZigBee HHAANN##11 Neighbourhood Area ZigBee Network (NAN) #1 HHAANN##NN Neighbourhood Area Network (NAN) #N #N ZigBee HHAANN##NN that the main focus of our scheme is to establish a secure and efficient communication between the two ends (i.e., smart meter and NAN). We assumed that the NAN gateway is securely connected with the utility server (US). Smart Meter HHAANN##11
