Abstract
The invention discloses a secondary encryption/decryption method, which is respectively processed twice encryption encoding to correspondingly form a first encryption signal and a second encryption signal. The first encryption signal is received and processed by first decryption decoding to form a first decryption signal. When the first decryption signal is different from the first encryption signal, the first encryption signal is received and processed by the first decryption decoding again. If the first decryption signal is identical with the first encryption signal, steps of receiving the second encryption signal and processing second decryption decoding is processed to form a second decryption signal. When the second decryption signal is different from the second encryption signal, the first decryption decoding is processed again. If the second decryption signal is identical with the second encryption signal, decryption action is finished. By means of the check action of the twice encryption decryption, when load is driven in remote control mode, maloperation caused by single decoding is avoided, and safety is improved.
