This caused great threat to the security of smart grid data. Integrity, confidentiality and availability of power terminal data are directly related to the normal use of various business systems, which has drawn more attention towards the terminal data security. To face the increasingly prominent terminal data leakage problem, improving the security of terminal data becomes more important.
