【 摘 要 】

This paper describes a method to improve the security of control signal transmission in substation by introducing third party authentication and applying encryption technology. We can use asymmetric encryption technology to ensure the safety of data transmission process. A third party authentication device is introduced to verify the rights and identities of both sides of the command and prevent the interception and tampering of command information. Use dynamic key and authorization expiration system to further protect control security. Finally, the character code is checked by the command and the error data is filtered effectively. This method can effectively prevent signals from being truncated or tampered and ensure the security of data. Restricting the operation crowd, isolating illegal users, protecting information security, greatly improve the information security of substation control process.
