To reach the demands of the real-time covert communication, the hardware implementation of a new kind of the high efficient information hiding algorithm is proposed. The proposed scheme can embed [log_2(n+1)] bits of the changed covert data under the condition of one bit in the coverwords of n bit. The embedding algorithm successfully applies to information hiding in speech. It is pointed out that the hardware solution based on two levels encryption, guarantees a very high level of security. The speed of the hardware can reach 85.7 MHz and the hardware 530 Mb/s of data by using 8 channel parallel processing. The design can generally reach the demands of the high speed and real-time covert communication.
