The invention relates to an elevator security encryption system. The elevator security encryption system comprises an elevator main controller, a car roof control module, an external call module and aprogrammable device. The programmable device writes encrypted data into the elevator main controller, the car roof control module and the external call module separately. The elevator main controllerwrites encrypted data into the car roof control module and carries out security authentication and locking on the car roof control module regularly. The elevator main controller writes encrypted datainto the external call module and carries out security authentication and locking on the external call module regularly. The encryption system can effectively guarantee the data security, prevents anelevator control system from being attacked by external equipment, and improves the security, integrity, confidentiality and reliability of the elevator control system.
