The invention provides a power business anti-
quantum cryptography migration progressive control method based on risk awareness, and belongs to the technical field of migration control, and the method comprises the steps: collecting key parameters of all to-be-migrated businesses in a power
system, carrying out the
standardization preprocessing of the collected key parameters, and constructing a business
feature matrix; acquiring relevant parameters of
quantum attacks in real time, and calculating a real-
time quantum attack risk value of each service to be migrated; based on the service
feature matrix and the real-
time quantum attack risk value, constructing a dynamic migration
rhythm adaptation model, and calculating a migration priority, a migration rate and a migration interval of each service to be migrated; and constructing a migration fault-tolerant and
recovery model, monitoring the migration process in real time, calculating a fault influence range and
recovery cost based on fault information, and executing corresponding adjustment operation. Accurate, dynamic and high-reliability control of anti-
quantum password migration of the power business is realized, safe and stable operation of the power business in the migration process is guaranteed, and the migration efficiency and the anti-quantum
attack capability are improved.
