Aiming at the security problem of message information exchange in intelligent distribution network, a security algorithm based on digital signature is proposed in this paper. An intelligent distribution network security algorithm based on public key mechanism is proposed. The unified format of message suitable for intelligent distribution network is discussed. The specific implementation method of message security for intelligent distribution network based on digital signature is studied. The performance characteristics of the algorithm are measured and analyzed on the current intelligent distribution network platform. The validation results show that the algorithm meets the requirements of communication security in intelligent distribution network and has very high practical value.
