Abstract: With the wide application of mobile terminals into smart grid, it is urgent on the agenda to ensure the more secure access of mobile terminal to power information network. In view of the situation that the mostly used public key algorithms of encrypted SD card is RSA, a new secure access solution of electric power mobile terminal is proposed by using SM2-crypto-system-based SD card. An analysis is made on the SM2-crypto-system-based SD card, the network and application framework of the proposed solution. Meanwhile, the proxy function and the SD card secure application function are tested by using the Android mobile phone as the electrical power mobile terminal, which validates the feasibility and safety of the proposed solution. The SD card has been piloted in a provincial power grid, and the result proves that the proposed solution can be used as a reference for improving the active defense ability of mobile terminals and promoting the localization of electrical power information security products.
