Abstract :
It is researched in the paper that non-linear system and its inversion are used to achieve signal encryption and decryption. Non-linear system and its inversion, which are of mapping relationship, are designed with BP neural network. The impulse signals are decoded with four dimensions to four dimensions, one of the systems encrypts and another decrypts. The result of simulation proves that it is reasonable in theory and workable in practice; the encryption and decryption system can come true easily. Being great secret effect and hardly decryption, the encryption and decryption system will be useful in future.
