Abstract：This article state a method to improve the security of control signal transmission in Substation. Which is through the introduction of third party authentication and application encryption technology. We can protect the security of the data transmission process. By using asymmetic encryption technology. And verify the authority and identity each other through drawing into the introduction of third party authentication devices to protect command information from being intercepted and tampered. And then re sealing command information with third party devices to ensure the security of transmission informations. And using dymamtic key and anthorization overdue system to further protect control security. Finally, checking the command with condition code to filter the error data effectively. This method can effectively prevent signals from being truncated or tampered. Ensure the security of data. Limiting the operation crowd, isolating illegal users, protecting information security, greatly improve the information security of substation control process.
