An encryption system of digital signals using synchronization of are disclosed. The encryption system comprises a transmitter of an encryption apparatus and a receiver of a decryption apparatus.The encryption apparatus includes a master chaotic device, a first integer modulation part for modulating the chaotic signals to be bit signals of integer type, a first inversion and transpositon part, a first code modulation part for modulating the chotic signals outputted form the first inversion and transposition part to ASCII code, a first logical operation part for generating encryption signals with the noise signals. The decryption apparatus includes a separation part for separating the encryption signals and noise signals, a slave chaotic device, a second integer modulation part for modulating the chaotic signals to bit signals of integer type, a second inversion and transposition part, a second code modulation part for modulationg the chaotic signals to the ASCII CODE, a second logical operation part for logically operating the chaotic signals of the ASCII code and the encryption signals and decoding the information signals. |
