Popis: With the increasing demand for image transmission in various fields including medical, military and multimedia, the security of information contained on these images has become a standing problem.. This work provides information security for images transfer for 160 Gbps over 140 km optical fiber link. Image encryption and decryption is maintained by applying blowfish algorithm via MATLAB software with the adaption of OptiSystem software to examine data transmission over 16 channels WDM system.. The proposed algorithm has provide a large key space, resistivity to differential attacks, anti-differential attack, brute-force attack and less correlation between adjacent pixels However, channel dispersion and signal attenuation has been controlled with the adaption of symmetric dispersion compensation map and an erbium doped fiber amplifier (EDFA) at the end of the fiber link. Our WDM system design has reached a high figure of merit of about 22,400 as compared with different previous schemes. Moreover, to provoke the power of the proposed cipher algorithm, key space, correlations, histogram analysis and different security analysis has been studied and compared with other algorithms.
