摘要

Intensive studies have been done to get robust encryption algorithms. Due to the importance of image information, optical encryption has become played a vital rule in information security. Many optical encryption schemes have been proposed but most of them suffer from poor robustness. In this paper two proposed techniques will be presented for optical encryption to be robust to severe attacks; composite attack. One of these approaches is represented by hybrid use of both steganography and Discrete Wavelet Transform (DWT) based optical encryption and the other one in which Fractional Fast Fourier Transform (FRFFT) has been used with DWT. Not only new techniques will be presented but also a new proposed chaotic map has been developed as random keys for both algorithms. After extensive comparative study with some traditional techniques it has been found that the novel algorithms have achieved better performance.
