Abstract: A data communication apparatus and a method using a non-periodic resynchronization process of a random sequence are provided to transmit effectively synchronization separation detection data by inserting the synchronization separation detection data as a watermark into original data. A data input unit(101) receives plaintext data of a digital type. A watermark generation unit(102) generates a watermark from synchronization separation detection data. A watermark insertion unit(103) receives the plaintext data from the data input unit, receives the watermark from the watermark generation unit, and inserts the watermark into the plaintext data. An encryption unit(104) encrypts the plaintext data including the watermark in order to form a random sequence. A transmission unit(107) receives and transmits the random sequence. A reception unit(109) receives the random sequence. A decoding unit(111) receives and decodes the random sequence. A detection unit(112) detects the watermark from the plaintext. A synchronization separation detection unit(113) compares the watermark with the stored watermark in order to determine a synchronization separation state. An output unit(114) outputs data or perform a resynchronization process according to the consistency of the detected watermark.

Abstract: PURPOSE: A key transceiving method using frequency band division is provided to assign transmission key bits to each divided band, and to forcibly insert intrinsic frequency components to transmit and receive data. CONSTITUTION: A transmitter generates a key to be transmitted(S201), and forcibly inserts preset spectrum coefficients into a corresponding band according to a bit value(S203). The transmitter scrambles the entire transmission bandwidth to safely transmit a key bit(S205), and converts into a time area signal by performing an IFFT process(S206). The transmitter changes the signal into an analog signal to transmit the analog signal(S207,S209). A receiver receives the analog signal(S211), performs an A/D conversion(S213), and carries out an FFT process(S215). The receiver descrambles displaced frequency coefficients into an original position(S216). The receiver extracts energy information of a spectrum, decides whether the assigned key bit is '0' or '1'(S217), and restores entire key bits(S219).

Abstract: PURPOSE: An FFT(Fast Fourier Transform) scrambling and descrambling method is provided to firstly scale an amplitude of an FFT signal in a transmitter, and to scramble a position of a frequency component, in order to modulate an amplitude of the frequency component, thereby reducing residual intelligibility for an original signal. CONSTITUTION: A scrambling process(20) is performed as follows. An analog signal(201) is sampled to a sampling frequency, and is converted into a digital signal(202). An FFT processor binds digitally converted data in certain blocks, performs an N-point FFT process, and converts the data into a frequency region signal(203). A scaling table(220) is multiplied by a frequency component, and an amplitude scaling operation(204) is carried out to generate an amplitude-modulated signal. A position component of the frequency region signal is replaced(205), and an N-point inverse FFT process is performed(206). The signal becomes a real number sequence signal, and is converted into the analog signal(207), then is transmitted(208).
