The invention discloses a secure data storage method and device based on an alliance block chain. The method comprises the following steps that a data collection node sends an uploading request to a data storage node after the data collection node obtains power grid data; after the data storage node authenticates the uploading request, the data storage node receives encrypted power grid data and decrypts the encrypted power grid data through an own private key in order to obtain power grid data; after the data storage node verifies that the power grid data conforms to requirements, the data storage node stores the power grid data into a local database; and the data storage node broadcasts the stored power grid data to other target data storage nodes. According to the method, the data sharing transparency of the power grid data is improved, and meanwhile, the stored power grid data is guaranteed to be difficult to lose, and the security of the power grid data is improved. In addition, the secure data storage device based on the alliance block chain also has the effects.
