The invention relates to the field of elevator data transmission, provides an elevator main controller and an elevator board card communication encryption method, and aims to solve the problems of poor privacy of data exchange and low security of data exchange between equipment caused by plaintext transmission of data communication between a main controller and a peripheral control board. The method comprises the following steps: acquiring a plurality of first pre-stored data from a plurality of preset first storage units, and determining a first secret key according to a preset logic; obtaining second pre-stored data from a plurality of preset second storage units, and determining a second secret key according to preset logic; obtaining a dynamic secret key generated by triggering a dynamic password rule, and generating a secret key string based on the first secret key, the second secret key and the dynamic secret key; and based on the secret key string, performing encryption operation on the to-be-processed data by utilizing an encryption algorithm. Communication data between the main controller and the peripheral control panel is effectively protected from being cracked and broken through the multi-layer secret key, and the safety of the communication data and the safety of the elevator are guaranteed.
