Step S202: and the power grid terminal generates power grid data, constructs encrypted power grid data and sends the encrypted power grid data to the slave block link points.
The power grid terminal generates power grid data in a normal transaction process, and in order to guarantee the safety of the power grid data, the slave blockchain client of the power grid terminal executes encryption operation on the power grid data to generate the encrypted power grid data.
Referring to fig. 3, the encryption operation may be implemented in the following manner:
step S301: and the power grid terminal calculates the power grid data by adopting a secure hash algorithm to obtain the power grid data fingerprint.
In order to ensure the authenticity of the DATA, the SHA algorithm in the secure hash algorithm may be used to calculate the DATA content fingerprint of the power grid DATA, and the calculation formula of the power grid DATA fingerprint m corresponding to the power grid DATA is detailed in formula (1).
m＝Hash SHA (DATA)……(1)
Step S302: and the power grid terminal signs the power grid data fingerprint by adopting an elliptic encryption algorithm and the private key to obtain a signature.
In order to ensure the security of the data content fingerprint m, an elliptic cryptosystem (ECC) algorithm in a signature algorithm is adopted to perform signature operation on the power grid data fingerprint m.
The parameters involved in the signature operation of the ECC algorithm include: the system comprises a large prime number P, coordinates of a base point G, a temporary private key k, a temporary public key P and a private key DA of a power grid terminal.

The relationship between the public key and the private key is as follows: x = rP, x i ＝r i P, function e is a bilinear pair function.
If the left side and the right side of equation (7) are equal, it indicates that the aggregated signature is correct, i.e. the distributed aggregated signature is successful.
Step S504: and after the aggregated signature is verified to be correct, determining that the distributed aggregated signature is successful.
Step S203 then proceeds to step S204: and the main block chain node stores the power grid data.
