Abstract
A method of protecting data transmission, which is used to protect data transmitted by broadcasting way from being received illegally, comprises the steps of: (1) on transmission end encrypting to be transmitted data by one time-related procedure; (2) through one transmission medium transmitting encrypted data to receiving end; (3) on receiving end decrypting received data by one time-related procedure, if time signal of decrypting and encrypting on receiving end host is synchronous, then output data of decrypting procedure is correct, otherwise output data of decrypting procedure is wrong.
