With the gradual development of the power grid computer system, more and more intelligent power equipment is connected to the service system, and the security of service interoperability in the computer system is gradually concerned. This paper evaluates the security problems of power grid computer system, combines PKI system with OPC UA protocol, and uses data transmission technologies such as digital digest and symmetric encryption to ensure the security of data transmission.
