Abstract
The application discloses a kind of power distribution network multi-element data complementary encryption communication method.The application includes the following steps:S1: the distributed acquisition system respectively acquires multiple data in power grid into local host;S2: after local host comprehensive analysis and judgment to multiple data, according to the time stamp of acquisition, multiple data and analysis and judgment result are respectively encrypted and stored in local database after partition;S3: after receiving the legal communication request from the distance, the encrypted multiple data stored in local database is mutually secondary encrypted according to the time stamp of request, and the secondary encrypted multiple data is transmitted to the remote database through external network, and the secret key is transmitted to the remote database through private network;S4: remote database is sequentially decrypted according to the secret key to multiple data, and is stored according to the type of multiple data partition.Multiple data complementary encryption, encrypted data is transmitted through external network, and the secret key is transmitted through private network, which ensures the transmission efficiency of large amount of multiple data in power grid system, and also ensures the safety of data.
