In the smart grid scenario,the problems of lacking authentication and the ability to verify the secure status of the both ends in the initial computing environment still exist.To fix these problems,this paper proposes a trusted network connection(TNC)scheme based on SM algorithms.Firstly,the scheme realizes the SM algorithms based on FPGA(field programmable gate array)to meet the independent and controllable security requirements.The security of mobile terminals under smart grid is enhanced from the physical level.Secondly,the scheme innovatively applies TNC technology to smart grid mobile terminals,and designs a data security transmission scheme suitable for terminals in smart grid system,which ensures the security of communication links and the legitimacy of terminals.Finally,we implement the prototype system and conduct simulation experiments.The experimental results illustrate the effectiveness of the proposed TNC scheme,and it has a good application prospect in smart power grid.
