An Implementation of Hyperchaotic Encryption Though Direct Sequence Spread-Spectrum Image Steganography (DSSSIS)

Due to its high robustness attribute, spread-spectrum steganography for multimedia signals is appealing and is used widely for a variety of applications. In recent years, one similar application of spread-spectrum image steganography (SSIS) has shown promise in that it can assess the QoS (quality of services) of multimedia services without any prior knowledge. This study offers an outstanding and secure algorithm for stegno pictures and a Direct Sequence Spread-Spectrum (DSSS) methodology. This mechanism is based on Code Division Multiple Access (CDMA) for the encryption and decryption-based approach. Through a 127 bit Barker code sequence, data pulses are produced by utilizing the high-speed BPSK modulation method. The Xilinx ISE simulator is used to complete the design and simulate it using VHDL. The hardware model is put into practice in CoolRunner II complex programmable logic device (CPLD). The system for four users to transmit eight bits of parallel data is designed in the simulation portion. Dynamic CDMA and code hopping increase the system’s capacity and security.
