[0108] The present invention directly performs intranet electronic signature and electronic seal on power grid engineering documents in the local area network, while only the encrypted power grid engineering documents can be obtained through the Internet in the external network; the encrypted engineering documents obtained through the Internet need to be decrypted before signing and sealing; thus, the risk of data leakage is reduced when the power grid engineering documents are managed on the Internet. In combination with blockchain technology, the decryption key, electronic signature and electronic seal are issued to users on the Internet through the nodes on the blockchain, and the decentralization of the blockchain is utilized to improve the security of the key; at the same time, the data transmission operation of the encrypted power grid engineering documents is not performed between the first node and the second node on the first blockchain and the second blockchain, which ensures that other nodes on the first blockchain cannot obtain the encrypted power grid engineering documents, further improving the data security performance.
