Abstract Traditional maintenance of new equipment and technologies has high labor cost and low efficiency. So remote maintenance has been widely used, but it also brings security problems. This paper designs remote security communication and key operation non-repudiation, based on IEC 61850 file service and national security algorithm. It solves the problem of sensitive information in plain text, and that the user's identity cannot be verified. Then, it ensures the security of the entire maintenance.
