Abstract
Power Internet of Things (IoT) is the application of IoT technology in the field of power grid, which can better control all kinds of power equipment, power personnel and operating environment. However, access to mass terminals brings higher requirements for terminal authentication and key management for the power IoT. And the traditional public key infrastructure (PKI) and identity-based public key cryptography (IB-PKC) exist the problems of certificate management and key escrow. Therefore, the paper proposes a novel authenticated key agreement scheme based on the certificateless public key cryptography (CL-PKC) mechanism. In addition, the proposed scheme is proven with the improved extended Canetti-Krawczyk (eCK) security model. Finally, the implementation of the authenticated key agreement protocol is given based on the actual application requirement of the power IoT, and the analysis and comparison of the simulation demonstrates that the proposed scheme has higher efficiency and would be suitable for the power IoT.

Summary
Power IoT is the specific application, implementation and evolution direction of the. The process of designing an efficient authenticated key agreement protocol, achieve identity authentication and develop a key agreement that includes the privacy, integrality and undeniability of communication data with massive power IoT terminals has become a focus in current research. The authenticated key agreement scheme could be implemented by three cipher systems: PKI, IB-PKC and CL-PKC. This paper proposes a novel authenticated key agreement scheme that could be suitable for the power IoT, which can effectively improve the security of the power IoT and the grids. An efficient authenticated key agreement scheme based on CL-PKC has been proposed, which uses simple point multiplication of elliptic curves to replace complex bilinear pairing to make it simpler and more practical for the terminals with limited computing resources in power IoT.
